Youtou Shinnoken: Demon Sword Chapter 58: Living Sin (Part 10)

The B-Class Toguro fights the S-Class Yusuke Urameshi before unleashing a power beyond the one he had before he died.

Tenro, the reincarnation of Makoto Shishio, finally makes an appearance and wreaks havoc against all the Reikai Senshi before facing off against the man who killed him originally: Kenshin Himura.

The original source of this idea comes from Chad Yang. I continued his story idea found here.

The rest of the chapters of my Yuyu Hakusho and Rurouni Kenshin crossover fan fiction are available here and here. Enjoy.

First | Previous | Next (Youtou Shinnoken) | Next (Demon Sword)

About a hundred years or so ago...

In 1878, after fighting Kenshin "Battousai" Himura to a draw, Makoto Shishio died in a literal blaze of glory (through his own spontaneous combustion when his overheating body broke its limits) and went to Hell.

When he got there, he ended up right before the imposing, gigantic figure of Enma Daio, who asked him, "What are you doing here, mortal? Go back to the Gates of Judgment in order to be judged."

Shishio then replied, "Get out of my throne. I'm the new King of Hell."

Chapter 58: Living Sin (Part 10)

***

Back at the Okushiri Military Base...

A shouting, crying Yahiko kneeled in front of Botan's unmoving body, seeing the huge hole in Botan's person.

A hole in the shinigami who somehow was also his kendo master from a former life, Kaoru Kamiya  (he didn't quite understand it).

Had he failed again? Like before, when Enishi Yukishiro...?

No. He would not let Kaoru down again. Not after what the Kenshingumi had been through right after Kenshin Himura died and...!

"Bloody Rain," said Yumi Komagata, who again made it rain blood mixed with what seemed like scalpels.

Right above the dark clouds filled with the scarlet squall were Houji Sadojima's shikigami (familiars) that looked like grim reapers in and of themselves due to their ragged clothes, faceless voids covered by hoods for heads, and long scythes.

And beyond them was Gatekeeper Itsuki, who had a mini-gun at the ready in order to test the limits of a solidified ghost body before it became incorporeal once more. Knowing that gunpowder had no spirit energy for Yahiko to neutralize.

"DOU GAMI! (GOD ON EARTH!)" Yahiko's earth-shattering technique blasted away the razor-sharp precipitation and Itsuki's suppressive fire into oblivion, allowing him to dissipate the slicing rain bullets around him and the soul-crushing pressure of the borrowed aura of the Onmyouji (Occult Priest).

"Insolent welp...!" Houji said the thing.

"TEN GAMI! (GOD IN HEAVEN!)" Myojin shouted as he did a much more powerful version of the God on Earth that shot him up high into the heavens. Even the nimbus clouds parted from the strength of his slash.

This rocked and shook the military base like an earthquake while the Tokyo Samurai Descendant himself approached the Onmyouji like the resulting tsunami of such an earthquake.

"INGA GAMI! (KARMIC GOD!)"

It was this technique that suddenly turned the poisonous miasma of the Overfiend into something else. Something filled with positive energy and life-giving, nourishing soul power.

Sanosuke Sagara then noticed how the crimson, purple, and black miasma of jaki surrounding them changed in color, texture, and volume. Flickering back and forth from a cool blue wave to a scarlet mess.

He then checked on Botan, only to gasp in surprise despite being a ghost that didn't need to breathe or have sudden oxygen intakes.

The hole in her chest caused by one of Itsuki's black holes had begun healing. The jaki surrounding them, as Sano suspected, was slowly being purified into reiki, which in turn the ferry-girl used to heal herself.

Not only herself, actually. She shared the wealth by beaming the spirit energy she absorbed unto Kazuma Kuwabara and Sanosuke too. Replenishing their depleted spiritual power and increasing their health at the same time.

A full restore for all her allies, if you would.

'What's going on here? Is this Yahiko's doing? Or hers?'

It was actually both.

Yahiko neutralized the overpowering potency of the Chojin's jaki just short of making it altogether disappear. Botan then purified the weakened negative energy into reiki she used to heal herself and the others while also powering them up, as though she filled the role of the Onmyouji for the Reikai Senshi (Spirit World Warriors).

Meanwhile, Kuwabara and Botan exchanged knowing glances.

They'd gone through this incident before. To be more specific, they witnessed Yusuke do the same thing Yahiko (and Kaoru) attempted to do firsthand.

It was when Urameshi got a hold of the Meikai Crystal and attempted to use it against the last Meikai God standing, Yakumo. The negative energy almost consumed him before his sheer willpower (and at the time hidden demonic lineage) turned the jaki into reiki instead.

Yahiko had decided it was easier to weaken the Chojin's overwhelming negative energy so that Kaoru could turn it into positive (spirit) energy instead of attempting to neutralize or seal it all at once.

The tag team of Yahiko and Kaoru allowed them to replicate what Yusuke himself did alone.

Break it down to its core components first, bit by bit.

The samurai boy then said, "BANZEN GAMI. (PERFECT GOD.)"

***

"Great fighters refuse to lose, but you refuse to win just to get back that feeling and exhilaration of conquering something greater than you. So what do you do now that you're in a world where nothing is greater than you?"

Those were Younger Toguro's words even as Yusuke Urameshi effortlessly tanked through and walked down his offense while blasting him to nigh-oblivion with the Renshya Rei-Gan (Rapid-Fire Spirit Gun).

'What the hell was that supposed to mean?!' Yusuke thought.

Was Toguro Ototo right? Had Urameshi become too powerful? Was he holding back his power level in order to drag out fights he would've easily won otherwise, thus endangering the lives of those he protected?

Ha. As if.

Those words truly did sound deep. They'd sound even deeper and more meaningful if said by a guy who wasn't getting his ass kicked care of him.

If that were true, he would've already hunted down and killed the Chojin himself. He wasn't even the most powerful being in Makai (Demon World), let alone all three worlds. He was a level below the likes of Mukuro and Yomi as well as his deceased ancestor/father figure Raizen.

Not to mention Raizen's old comrades having power levels so high they could band together and conquer both the Human and Spirit Worlds if they so chose.

No, instead of it being a case of Yusuke growing too ridiculously powerful, it was instead a matter of Toguro remaining stagnant and weak by comparison.

The martial artist who belonged to the "baby boomer" generation might've been powerful for a demon not trapped in Makai and blocked off by the Spirit World Barrier. However, he was a pissant compared to the likes of the monsters Urameshi eventually faced in the Demon World Unification Tournament.

On top of all that, Yusuke didn't want to hear that nonsense from the King of Holding Back. The Emperor of Power Percentages.

"Rando's Kugai (World of Suffering) is a low-level technique used by monks to empathically feel the pain and suffering of those around them. The fact that you're still suffering from its effects isn't because of its curse but because of how you reacted to it."

Yusuke frowned. Indeed, for quite sometime since his fight with Rando, every punch he threw at his opponents he also felt. For once, he found out what it was like to get punched by himself.

However, it also served as his training. The more he felt his own punches, the more resistant he became of his own power, thus raising his threshold of pain and his ability to take a punch. He could dish it out and take it.

He wasn't sure he could say the same about Toguro.

His ripcord muscles strained to their utmost, the Younger Toguro ended up having his muscle fibers ripped apart, cracked, and shattered like pottery. The anabolic state he used to grow his muscles to absurd sizes ended up completely wasted because he couldn't handle A-Level to S-Level bursts of power.

Yusuke nevertheless conceded one point to Toguro: The teenager did miss staking his life and limb to defeat an enemy, using all his strength to defend his friends and family.

He hadn't really done so lately. Not really. The last time he had a satisfying match was against Yomi.

Ever since then, his enemies mainly resorted to trickery reminiscent of Kido Asato freezing him with his shadow powers or Hiei kidnapping Keiko Yukimura to defeat him.

All of the Chojin's Shin Ju ended up as weaklings compared to Urameshi. Each and every one of them. To go against them with his full powers would be a waste of effort.

Like lighting a candle with a flamethrower or cutting grass with a chainsaw. Complete overkill.

Then again, wasn't this also the reason why Toguro, even though he was only B-Level, tended to hide his power level or only use a percentage of his power?

Huh. They were more alike than he thought.

***

Botan smiled in spite of herself. Or rather, her lips curved upward on their own and then said things not of her own volition due to her astral body's second inhabitant: Kaoru Kamiya.

"There it is. The Perfect God. That's Yahiko's answer to mastering the Mujinken."

A hundred years or so ago, Kaoru originally taught Yahiko the Tenchijinken (forethought-based techniques involving the prediction of an opponent's moves) and taught Yutaro Tsukayama the Mujinken (reflex-based techniques that reacted to whatever the opponent did in the heat of the moment) to fill in their respective weaknesses.

The two were actually more suited for each other's techniques, since Yahiko fought more off-the-cuff while Yutaro fought more methodically.

She intentionally sealed away the techniques that played to the two's strengths so that they could overcome their weaknesses with the opposite techniques, believing that someday they'd figure out how to do each other's ultimate attacks down the line anyway.

While the Inga Gami showed Yahiko's version of methodical fighting (with him focusing on every counterstrike to unleash the best counters without any wasted movement or energy), it was the instinctual Banzen Gami that showed his fullest potential.

Yahiko was more of a natural with the Perfect God than the Karmic God. It was the opposite for the more thoughtful Yutaro (who now went by the name and identity of Natsuki Shinkai/Xinhai).

"INSECT!" sneered Houji, his wide eyes glowing red, his voice booming like thunder as he produced what seemed like an endless stream of shikigami. Only for Myojin to seemingly cut and disintegrate them with a couple of reflexive waves of his sakabatou.

He wasn't even looking at the reapers as every reflexive slice of his blunt sword blew them apart and sent them to oblivion, his gaze aimed solely at Sadojima

The miasma of black jaki turned into white and blue shining reiki as Myojin neutralized it and Kaoru converted it into pure reiki. Once he reached Houji, their respective weapons clashed, the entire area split between the morning light colors from behind Yahiko and the pitch-black darkness from behind Sadojima.

It was like the clash of day and night, with the point of impact serving as their dusk or dawn. Twilight or daybreak.

To Houji's alarm, his scythe then started to crack and break. 'What the HELL is with this stupid brat!? I thought our only real threats are the Youkiri Battousai and Urameshi Yusuke! Chojin-sama, HELP!'

***

Instead of going down from the barrage of Rei-Gan shots, Toguro merely said, "Stop wasting energy," as though Yusuke left the light or electric fan turned on or something.

To Yusuke's surprise (or perhaps disappointment), the B-Class Toguro reacted to the Spirit Gun bombardment the exact same way as he did during the Ankoku Bujutsukai (Dark Martial Arts Tournament): By attempting to charge at the growing spirit energy bullets to stop them with his bare hands and feet as well as his purely anabolic, hugely muscular body.

And just like that, it was over. With Toguro face down on the ground, his body shattered and torn from its exploded musculature. A tall, lean husk of its former self.

Another one bit the dust. Like the rest of Yusuke's revived enemies that came back stronger because of the Chojin but not quite strong enough to take him on.

To Yusuke's mild surprise, Toguro was still "alive".  Or this revived zombie version of himself made by the Chojin's own personal Dr. Frankenstein was still moving.

The muscleman mercenary then said, "I'm merely at B-Level and I was able to push you this far? Your fighting senses have dulled, Urameshi Yusuke."

"Oh really? Well, I've discovered that at this point, no one could beat me but myself. You're welcome to prove me wrong, though," said Yusuke.

Again, Urameshi pulled something right out of Toguro's playbook. They both looked down on people who weren't on their level.

Toguro looked up at the night sky, which rekindled his memories. The Shichousei (Death Omen Star, also known as the Lifespan Star, Jumyoboshi, Alcor, or 80 Ursae Majoris) wasn't present near the Big Dipper.

"I can't see the Shichousei in the heavens."

"W-What are you talking about, Toguro? Have you gone cuckoo?"

Legend had it that when two warriors fought to the death under the Star of Death and it shone upon one of them, that person would die.

Was the star missing because he was already dead? Or because this wasn't much of a death match?

Fine. He'd turn this match into a death match then.

On the other hand, other Japanese myths and legends alleged that when a person couldn't see the Lifespan Star, he'd pass away within a year. That was appropriate since Toguro himself was not alive anymore.

Thusly, every broken bone from his body reset and healed, but instead of going back to normal, they formed sharp calcified bone spurs that protruded right out of his craggy, callused body like horns or thorns.

"...I knew it! You still had another form after 100%, you son of a bitch! CHOU REI-GAN! (MEGA SPIRIT GUN!)"

As Toguro got a power boost from the way his body decided to recover from his injuries, he punched back the Chou Rei-Gan Yusuke fired at his changing form before punching the teenager as well with his bone spur claws on his fist right at the moment of impact, quadrupling its effect.

He just jumped from Class-B to Class-A in a mere second.

"Ooof!" The world-stopping punch emptied the air from Yusuke's lungs.

"My former 100% has actually become less than a percentage point of my power, but for the sake of giving you a point of reference, I'll base my power increases on what was 100% of my power."

He grew about as big as his 100% of 100% form, perhaps even a little bigger, but this time around the demonized behemoth's black hair turned as grey as steel along with the rest of his vascular body that was covered with huge bony protrusions.

"So you can call this form of mine as me at 500% of my power."

"Whatever! HYAKU RETSU-KEN! (HUNDRED RENDING FISTS!)"

Appropriately enough, the attack Yusuke then used in response to Toguro's transformation was one he saw on television from his favorite anime show as a child of the 1980s, "Hokuto no Ken (Fist of the North Star)".

The Shichousei or Death Omen Star was, after all, also referenced by the same program.

Honestly, it was just Urameshi going ham on an opponent by randomly striking his heavy-handed punches at every opening available to him, with him naming the "technique" after the fact.

***

The devastation of the Okushiri Military base extended outward, with the pairs of Kazuma and Yumi as well as Sanosuke and Itsuki traveling eastward in a trail of devastation that followed Yahiko's own blaze of glory.

The green comet that was the Tokyo Samurai Descendant clashed and burned through the spherical cloud of miasma protecting Sadojima, like a shooting star entering the atmosphere.

The two pairs of enemies fought tooth and nail for proper positioning. The Reikai Senshi pushed the Chojin's forces back to protect Myojin from their interference.

Sanosuke punched through everything Itsuki threw at him from his hyperdimensional portals and busted portal gun. Sano also dodged the dense scattershot black holes and threw pavement debris at the Gatekeeper for good measure.  

Meanwhile, Kazuma fought from afar using his blade that can literally cut through anything and anywhere in order to slash apart every attempt of the wind vampire Yumi to blast tornadoes and energy-absorbing jaki at him.

Finally, Myojin himself struck the Chojin's (and at this point, it was the Chojin controlling the Onmyouji) scythe hard, the blade covered in miasma and dark energy.

The tides of battle then turned.

Using the jaki Kaoru purified into reiki, Yahiko's green aura became denser and denser, creating a white shining void at the center of his body that sucked the darkness of the Chojin away. Acting like a reverse black hole or even white hole that absorbed all of the Overfiend's darkness into his pure light.

'This is it, Botan,' thought Kaoru "telepathically". 'This is the power of Mu (Void). The power of emptiness.'

'Emptiness...?' repeated the ferry-girl.

'Yes. A true martial artist is able to fight with instinct, freeing his mind of all thought and distractions, leading to a Zen State. Yahiko manifested this Zen State into his unique skill: Neutralizing spiritual energy.'

A second later, all energy from everyone dissipated, and from there Houji's scythe shattered like glass as both he and Yahiko plummeted into the docks of the Okushiri Pier.  

The samurai spirit fell into Ryu Tsui Sen (Dragon Hammer Flash) stance and slammed Sadojima into one of the metal crates of the pier below them with an emphatic crash.  

"You stupid kid! I'll show you! ETERNAL...! Wait, what?! My powers are gone!"

Yumi Komagata attempted to do the Hi-Ougi (Hidden Art) of Vampire Martial Arts—a move stronger than the energy-sapping Blood Wind—but nothing of the sort manifested before her. Her aura, the energy she gathered from sucking many a soldier's blood, had disappeared.

The same happened to Itsuki, who couldn't summon his Reverse-Man or escape into his pocket dimension any longer.

Yahiko's reiki had also went out, which normally was dangerous for a ghost but he somehow reached homeostasis with the way he cancelled out the Chojin's jaki.

His dense green aura had now completely neutralized the powers of everyone near him instead of merely mitigating their flow, including the now unconscious Onmyouji.

Like how no light could escape the event horizon of a black hole, not one shadow of the Chojin's dark energy could exist amidst the blinding green light of Yahiko's converging spiritual aura.

However, as a consequence, even Yahiko's allies lost their powers as well, as though he was acting as the reverse version of the Onmyouji. Instead of boosting the powers of those in his vicinity, he nullified them.

Regardless, Sanosuke and Kuwabara immediately took advantage of the loss of powers from Itsuki and Yumi with their physical strength, with the former beating Itsuki to a pulp and Kuwabara breaking the umbrella and fan of Komagata bareheaded before tackling and pinning her down.

"Give it up, lady. You lost," said Kuwabara. "You can't cheat your way out of this one by resurrecting your goons every time we defeat them. Your precious Onmyouji's down for the count."

Yahiko "heaved" a sigh of relief despite being a solidified ghost who didn't need to breathe. "It's finally over."

Botan giggled in glee. "We did it! You did it! The number one pupil of Kamiya Kasshin! I'm so proud of you, Yahiko!" The last few parts of that statement was Kaoru talking.  

Sano looked at his own bloody fists and winced. 'We've won, but why do I feel like it's not yet over? Like there's still something afoot.'

Even though the blood from his right fist wasn't his own but Itsuki's, it burned and ached something fierce. Like he broke his hand or something. 'What's going on? I have a bad feeling about this.'

Sanosuke's bad feeling then turned into reality.

***

At Class-A, Yusuke Urameshi's Hyaku Retsu-Ken would've turned the B-Plus Toguro into mince meat. Or roadkill.

At Class-S, his Hyaku Retsu-Ken would've turned mountains like Mt. Kannon, Mt. Kamui, and even Mt. Fuji into molehills, plains, or even outright trenches and canyons as deep as the United States of America's Grand Canyon.

Like he was a pint-sized Paul Bunyan.

The teenager harrumphed. "Really? 500%? Like I'm fighting 5 Toguros at the same time? So what? That's still nothing compared to the demons I've faced since defeating you, Toguro...!"

The bone-breaking punches cracked the shell of Toguro's chitinous muscle armor bit by bit. However, in turn, Toguro let his fists fly as well but in a more methodical manner.

Targeting his punches at Yusuke's openings rather than punching randomly. Using his martial arts experience to take down the stronger foe.  

His bony yet muscular fists pounded on Yusuke's smaller body, cracking bones here and there.

Yusuke's fists ached from every punch he did on the rock-solid body of Toguro, the multitude of Spirit Cuffs holding his power back also getting pushed to their limit. The restraining cuffs and seals he placed upon himself were at their near breaking point from him merely flexing his immense power.

Thank goodness the likes of Yomi, Mukuro, Enki, and the rest of Raizen's friends (as well as Raizen himself when he was alive) put him in his place early on regarding what real power looked like, or else he'd be full of himself right about now.

The Toguro with chitinous bone spurs and keratinous horns all over his muscle-bound body ended up breaking each and every one of his thick, calcified bones from the impact of Yusuke's attacks.

Toguro's bones rattled as micro-tears appeared all over his muscles and tendons. Despite this, he pushed forward. Like his older brother, he healed quickly, which alerted Urameshi that he still had something in his sleeve.

"All right. Then how about this? TAKO NAGURI!"

The Octopus Assault—Yusuke's version of the Kuzu Ryu Sen (Nine-Dragon Flash) that hit 8 times instead of 9 times in an instant—hammered the horned gray body of the zombified and demonized Toguro before he could get the chance to stab, gore, or spear Yusuke with his many protruding bone spurs.

Urameshi once heard that it took either 23,034 slaps to cook a chicken. Either that, or a slap traveling at 1,665.65 meters per second.

He wasn't sure about the math, but he cooked Toguro's goose at a rate of 8-16 punches a second with every punch traveling at 1,000-2,000 meters per second, so it would've took about 20 minutes of non-stop Tako Naguri to get to around 20,000 punches or 2,500 super-powered Tako Naguri.

Or he would've cooked/burned 20,000 whole chickens with his speedy punches at around the same time it took to cook a chicken in the oven.

However, it was at the second minute that Urameshi broke his hand. He hit a hard shell reminiscent of Usui's shield.

From the pile of minced meat, torn muscle cords, and viscera emerged yet another Toguro form.

What stood before him wasn't the spurred behemoth Toguro but instead a fully armored Toguro, with every inch of his body covered in craggy white bone.

As though his shattered bones healed wrong and ended up calcifying right on top of his pulsating muscles. He broke the calcified armor in sections by flexing his limbs in order to give his new outer shell moving joints.

It also made him look like a white lobster man, thought Yusuke in chagrin.

"This is 1,000% of my power. 100 times the power of my 100% self."

***

At the Okushiri Pier, around 9:47 PM...

The mangled remains of a man landed right in front of Reikai's finest from out of the shadows of the dark harbor.

The Reikai Senshi (and their accompanying shinigami) then felt goose bumps form at the napes of their necks—even the ghostly ones that didn't even have tangible skin, blood, or hair to make such a sensation possible.

Even Itsuki, whom Sano beat from pillar to post with bare-knuckle fisticuffs, looked none the worse for wear compared to the person before them.

He was bathed in blood and his torn clothes were dyed crimson because of it. He looked like he'd been ravaged by a pack of wolves.

The only thing recognizable about him was that he was male.  Probably.

Sanosuke was the first one to try and poke at the figure to see who it was. If he had a ten-foot pole, he'd prod the man with it. As it was, thanks to Yahiko manifesting his full neutralization powers, Sano couldn't even summon one zanbatou right now.

The street fighter then stumbled back, which made Kazuma ask, "What's wrong? Who is it? Is that one of the Chojin's Shin Ju or whatever?"

Botan gulped, hoping against hope that the man before them was the injured body of one of the New Ten Swords instead of one of the Spirit World Warriors.

Before Sano could answer, someone else answered for him.

"That's what remains of Hajime Saito. The former captain of the Shinsengumi's Third Unit."

"...What? Who said that?" demanded Yahiko.

The Reikai Tantei, the shinigami, and the Kenshingumi then turned in time to see the silhouette of a pony-tailed person from the distance.

There stood a human(?) of about S-Level power with sleeked-back hair, a lengthy ponytail, and a half-undone kimono that showed off his rippling swimmer's muscles on his long build.

As realization dawned on them one by one, their mouths went agape, practically unhinged from their upper jaw.

The blood drained from Kuwabara's face while the three spiritual beings' faces (Botan/Kaoru, Sano, and Yahiko) looked more transparent than usual.

The ghosts all looked like they'd seen a ghost (ironically enough), forgetting they were ghosts themselves. Gasping for air they couldn't breathe anymore.

Even Kuwabara, who was alive, looked like he'd seen a ghost himself or even turned into one.

The man, who himself was a bloody mess with stabs wounds and cuts at every inch of his body, held something in his arms.

It was his trophy. His prize after a hard day's battle.

It was the head of his enemy. It was the head of Hajime Saito.

Botan screamed. Or rather, Kaoru did.

The Kamiya Kasshin Master couldn't believe that Kenshin's greatest rival who was so famous he became a Japanese historical figure later on had been defeated.

On the other hand, Botan—through centuries of being a death goddess—had seen worse things before, so she was desensitized enough to not scream. Her own feeling of dread was around the same level as Kaoru's, though.

The pony-tailed assassin then took one look at the Kenshingumi sans Kenshin, the Reikai Tantei sidekick, and their shinigami babysitter then sighed.

"Oh, no one but weaklings left? Pathetic. Imagine, after such a delicious meal, I'm left with leftovers and expired food."

The new arrival then placed Saito's head beside the rest of his body. Almost reverently. "Rest in peace, Saito Hajime. You were truly a worthy rival. I acknowledge you."

"You killed Officer Fujita! You BASTARD!" screamed Kuwabara, a knife-sized Rei-Ken ablaze with reiki and righteous indignation in his grip.

Kazuma would've produced a full-length Jigen Tou with the rage he felt, but Yahiko's neutralizing presence kept his powers in check.

"Wait. Boke (Fool), he's...!" Sano trailed off, moving in front of Kuwabara to block him from doing anything hasty. 'If anyone's going to do something hasty, it was going to be me!' thought Sagara.

"Who are you?" said Yahiko as he pointed his sakabatou at the stranger.

"I'm Youkiri Tenro (Tenro the Demon-Slayer). Remember that name before I send you back to Heaven."

***

Yusuke quickly checked his Spirit Detector. Toguro was now at A-Level with his Bone Armor form. Around the same power level as the most powerful members of the Reikai Tokubetsu Bouetai (Spirit World Special Forces).

This turn of events definitely piqued his interest. Somewhat. Maybe this time, he'd get the battle he so craved from this new version of Toguro since being defeated by Yomi in the Makai Tournament.

However, the extra layer of bone armor made it harder for Yusuke to break apart Toguro's muscle armor with mere punches, no matter what velocity he reached.

As though Toguro now had double the armor.

Also, in turn, the Class-A Toguro Ototo pummeled and stabbed Yusuke with earth-shattering strikes from his bony fists, horns, and claws as well as shattered pieces of his bone armor that kept calcifying and regrowing over and over. Layer by layer. Like samurai armor or shingles on the roof.

Stubbornly, the bloody and bruised Yusuke kept on punching the armored demon to push him away and give himself breathing room.

The bony yet muscle-bound contradiction of a monster that looked ridiculously gigantic yet unencumbered by his musculature having an extra layer of armor on top of it, turning him into a veritable tank with the speed of a Mack truck. He even hit like a truck.

However, as his wounds healed in Toguro Ani fashion, Urameshi realized that he had long ago surpassed the version of him that could get killed by being hit by a car. Or a truck. Or a tank. Or perhaps even a nuclear warhead. Maybe.

"Rei-Kou-Dan (Spirit Light Wave Bullet)."

One of his Spirit Cuffs broke as he put his hip into his punches and imbued his fists with actual spiritual power. They were already harder than steel because of the spirit energy contained within his body. When he emanated reiki from inside and outside himself, his punches also become explosive.

One reiki-imbued punch was all it took for him to crack the bone armor of Toguro at 1,000%. However, he wasn't done.

Perhaps he might have gone overboard, but he decided to punch Toguro 20,000 times in 3 minutes rather than 20 minutes. But it sure felt like 20 minutes.

Furthermore, these weren't just physical punches. His fists were set on fire with spiritual energy this time around. He shot out 20,000 Rei-Kou-Dan blasts, to be more precise.

Every supersonic punch had the impact of a blockbuster bomb, with it breaking the sound barrier and sending extra shockwaves to Toguro and all. Perhaps he'd become even more explosive than multiple blockbusters.

Perhaps Yusuke had turned into a teenaged nuke or warhead himself.

However, out of the mangled mess of bone armor emerged yet another Toguro. The armor that should've served as his coffin ended up becoming his cocoon for his newest metamorphosis. Which, to Yusuke's surprise, made him breathe a sigh in relief.

Yes! He could still push himself even further!

Was this excited feeling the same one that Toguro felt when, just a few years prior, Yusuke was able to withstand the might of 80% of his power when he killed Genkai in cold blood?

Regardless, a bronze-skinned, taller, and four-armed Toguro emerged from all that mush and burnt flesh he'd become earlier, impossibly towering even higher over Yusuke than before. His current ginormous form made his former seven-foot form look normal-sized in comparison.

His muscles were like taut steel cords now, like those used in heavy-duty tires and conveyer belts. Perhaps even harder. They were definitely harder than the pieces of thick calcified bone armor that they crushed like egg shells with a simple collective body flex.

"This is 100,000% of my power. This is what fighting 1,000 clones of my 100% self looks like."

Yusuke thought for a second what Toguro meant by that, only for him to test the theory out with an additional 20,000 Rei-Kou-Dan blasts in a minute. 20,000 palm blocks later and Urameshi now had a better idea of what his nemesis meant, followed by 20,000 counterpunches in between those blocks.

All in a minute's time.

'100,000% Toguro? He didn't even bother going to 10,000%? Jeez!' Urameshi thought as he got hit with a two-armed lariat that dragged his body across the landscape and river like a trailer home in a tornado.

This was it. This was the A-Plus version of Toguro.

Yusuke couldn't even hide the grin from his face even as this newest form of Toguro beat him to the punch every time.

Toguro at 100,000% had even tighter and tauter musculature with enough strength and torque behind them to break bones to dust. His ripcord muscles could handle punching velocities similar to that of or even faster than Yusuke's.

It also didn't help that Toguro now had a body that could accommodate four arms, thus giving him twice the hand speed and arm speed due to his literal extra limbs.

***

"...SHISHIO!" screamed Sanosuke at Tenro, his blood (ectoplasm) boiling. His right fist, which Makoto Shishio broke, pulsating like a second heart.

Even though Tenro wasn't wearing bandages and his skin wasn't burned to a crisp, Sano could recognize that voice and that demeanor anywhere.

'Shishio?' thought Kuwabara. So Tenro was the man who founded the original Juppon Gatana? Kenshin's greatest rival? The man who ultimately caused Kenshin's demise? The man who might actually be the alter ego of the Chojin himself?

The guy who not only pushed Hiei to his limits, but also possibly two of the Demon World's three kings, Yomi and Mukuro? Was Tenro Shishio's reincarnation or something...?

Before they knew it, they were suddenly faced with the final boss of the game.

The fighting spirit of Sanosuke rose high enough for him to defy the nullifying presence of Yahiko and form half of a zanbatou in his hands, which he swung at the (presumably) non-burned version or reincarnation of the ex-hitokiri and Meiji rebel known as Makoto Shishio.

With one swing of Tenro's Mugen Jin (Unlimited Blade) sword, Sagara's suspicions were confirmed.

"Secret Sword One: HOMURA DAMA!"

Shishio's signature Homura Dama (Burning Soul) technique where his sword burst into flame clashed hard against the 6-foot (normally 12-foot) horse-chopping sword, smelting it in the process like a blacksmith's forge in a shower of sparks.

"A weakling like usual, Sagara Sanosuke," sneered Tenro. "It's been a while, though."

"I don't understand. Wasn't Shishio supposed to look like a mummy or something? He's some guy who was burnt to a crisp and covered in bandages, right?" said Kazuma.

Sano answered, "Yeah, but obviously it's been 100 years. He must've found a way to get a new body, or ended up with a solidified soul, or got reincarnated as this Tenro clown."

Myojin gulped. He considered deactivating his powers to allow either Kuwabara or Sanosuke to attack the youkiri. However, if Tenro was this powerful with his spiritual power nullified, how much more powerful could he get when Yahiko's powers ceased working?

The disheveled Yumi then cackled in the background, the hole in her chest throbbing with a ghostly heart that the man before her had "stolen" from her.

"It's about time you got here, Tenro. What took you so long? Don't tell me the Miburo (Mibu's Wolf) gave you all that you can handle and then some."

Tenro harrumphed. "Perish the thought, Yumi. I merely gave my respects first to the Shinsengumi in the Battle of Hakodate Monument, and guess who I also found there? That's right, our favorite Shinsengumi Captain, Saito Hajime."

'Hakodate?!' thought Yahiko. 'That's four hours away from Okushiri! All the way on the other side of Hokkaido, at that!'

Sanosuke himself snarled at Tenro, his fist burning with pain and fire, as though it remembered how Makoto had shattered it when they'd faced each other back at Mt. Hiei.

'Hakodate is the place that served as the Shinsengumi's last stand. Did Saito go there to pay his respects to his squad? In the middle of our war against the Shin Ju? It's not like him to be so sentimental.'

The street fighter spared a glance at the remains of Hajime Saito. Unbelievable. Just earlier, he pushed several of the Shin Juppon Gatana to their limits, but now he ended up as dead as the rest of the original Shinsengumi.

Well, Saito himself was supposed to already be dead and buried in the first place, but this time around he got killed off for real by Shishio. Or Tenro, which was probably the reincarnation of Shishio.

Kuwabara turned towards Yahiko and said, "Kid, turn off your powers! I'm going to face off with the final boss one-on-one at my full strength!"

"But...!" the ghost kid trailed off before Botan filled in the rest.

"Kuwabara-kun, he can't. He's the only one sealing Tenro's immense power. If he was able to do that to Saito, imagine what he could do to us! Let Yahiko seal his power for now until either Kenshin or Yusuke arrives!" warned the ferry-girl.

"I DON'T CARE!" shouted Kazuma. "Let us face him at his full strength while we're also at full strength! As a real man, I won't back down!"

Tenro smirked. "Fine then. If you're not bluffing then come at me. In this world and beyond it, the same rules of nature apply. Only the strongest survive and the weak are food for the strong."

Sano's eyes narrowed. That convinced him that the man before him really was Shishio. That was totally a Shishio-type line. 'It's now or never. We just have to keep him here until either Kenshin or that delinquent best friend of Boke arrives!'

***

"REI-KOU-DAN!" shouted Urameshi, his Spirit Wave Light Bullets bursting through his fist like bolts of lightning from a Railgun.

The 100,000% Toguro blocked the punch with his elbow, shattering Yusuke's hand bones in the process. "Is this the power of an S-Level? Don't make me laugh. Me at 100,000% of my power is enough for you."

Toguro then grabbed hold of Urameshi's limbs with all four of his arms in a bid to tear the teenager apart literally from limb to limb.

Yusuke considered Toguro's statement for a second and then said, "Fuck that," before flipping the four-armed monster off with his right hand.

The mere idea that someone like Feng Xinhai or The "Beautiful" Suzuki was more powerful than Toguro just didn't sit well with Urameshi. At all.

At any rate, the middle finger he raised at the 100,000% Toguro then flowed with energy he'd been saving for a special occasion.

Yusuke discovered that he could actually save and store his dormant spirit energy as a reserve or extra Spirit Gun blast for use in case of emergencies since it usually took forever and a day to charge his Rei-Gan.

The energy for this one he'd been gathering for weeks' on end.

Also, in order for him to not mistakenly fire off his reserve Rei-Gan, he had this special energy bullet stored in his middle finger. This was how the new technique that he improvised when facing off against the S-Level Xinhai ultimately evolved.

This was his "Fuck You!" Spirit Gun. Also known as the "FAKKU GAN! (FUCK GUN!)"

The 100,000% Toguro chucked Yusuke away like a hot potato in order to better dodge the point-blank spiritual projectile then punted the Fuck Gun back to the teenager who fired it.

However, by instinct borne from his hundreds of fights against spiritually powerful humans and demons, Yusuke jumped away from the Fakku Gan, grabbed Toguro by the ankle, dragged him towards the ball of plasma fire he actually outran, and then threw the monster back into its path.

From there, as the 100,000% Toguro braced himself for impact, Urameshi emerged from behind him. Attacking him from the rear for good measure.

Toguro was now stuck between a rock and a hard place. Or between a demon and his energy blast.

"REI-KOU-DAN! SHOT GUN!" screamed the half-demon prince.

While the Fakku Gan blasted and disintegrated the giant from the front, Yusuke attacked with his Spirit Light Wave Bullets and reiki scattershot from behind, which kept even the four-armed monstrosity from defending himself from the upcoming onslaught surrounding him.

The charged-up blasts of energy in particle and wave forms bore on Toguro like plasma tides or a solar wind. An endless series of reiki tidal waves from the vast ocean of Urameshi's power.

Thanks to the extra pressure brought about by his stored energy blast from many weeks ago, Yusuke's Rei-Kou-Dan was able to penetrate deep into Toguro's core. The technique ripped apart the steel cord muscles of Toguro as they got softened by the comet of energy that cooked him alive.  

Then, as Yusuke had hoped deep in his unbeating heart, the mangled Toguro changed form yet again.

The same heart that stopped beating after Shinobu Sensui first pierced it felt like it had started beating again in anticipation. In excitement. In nostalgia, even.

Toguro still had more forms and powers up his sleeve. Just like old times.

And from there, out of the ashes and melted muscle of the 100,000% Toguro came forth the One Million Percent Toguro.

"One Million Percent. This is me at One Million Percent of my power, Urameshi Yusuke."

***

Kuwabara and Sanosuke attacked Tenro at the same time while Yahiko struggled on the spot to focus all his neutralizing powers on the Shishio reincarnation(?) alone.

Botan checked her Spirit Detector again. Hope sprouted anew within her heart. 'Yes! Tenro's power level went down to A-Level. He's still on the cusp of S-Level, but at least he's not as powerful as someone like Sensui or Xinhai! We have a chance!'

Tenro frowned. His aura of jaki had become fainter and weaker due to Myojin's powers.

'Hmmm. The Shin Ju had warned me about this impudent brat. Even Toguro Ani couldn't heal properly thanks to this kid's neutralizing reiki.'

As Yahiko slowly mastered his neutralization powers so that only Tenro was affected by them, the energy levels of Kuwabara and Sanosuke went up higher and higher than before, their auras flaring with spiritual might that was boosted by Botan's healing powers for good measure.

"JIGEN TOU!" screamed Kazuma, summoning his Dimension Sword.

"ZANBATOU!" shouted Sanosuke, producing his 12-foot long Horse-Chopping Sword.

"How appropriate. Isn't this just a reflection of today's society? The weak are using their great numbers to suppress their betters, not realizing that without the strong to lead them or the will to become strong themselves, they will end up extinct. The world stands on the shoulders of giants."

"SHADDAP! I don't know who you are, but all's fair in love and war," declared Kuwabara.

"Not all men are created equal. Like in the Animal Kingdom, some men are simply better than others. Equal opportunity doesn't guarantee equal results. Forcing equal results in an aberration of nature, like forcing animals to act like men, the pinnacle of evolution."

Tenro used a bare hand to grab hold of Kuwabara's Dimension Sword and used his other hand holding the saw-like Mugen Jin to block the full-length zanbatou.

"Ganging up on the strong can lead to the survival of the weak temporarily. However, their own respective weaknesses will sort them out. Their celebration of mediocrity will make them food for other apex predators in the future or have them subjugated by any of their own who decide to become rams instead of sheep."

The Youkiri then broke the Jigen Tou apart like it was made of cardboard instead of pure energy and stabbed Sanosuke's chest with it while also melting the zanbatou with his Mugen Jin's Homura Dama.

"Regardless, it is better to live one day as a lion than one hundred years as a sheep. These are... THE RULES OF NATURE!"

"AUGH!" grunted Sanosuke, his recently recovered soul flickering in and out of existence, his chest spewing ectoplasm, and his aura dissipating into pinpoints of light like a disturbed nest of bioluminescent fireflies.

He felt the light inside him slowly fade all the while.

"Bastard...!" said Kazuma, who repurposed the broken shards of his Jigen Tou and shot it pointblank at Youkiri Tenro's face, turning them into "REI-SHURIKEN!"

He should've hit him with the projectiles from a distance, though. The first few blades bounced off of the intense aura of jaki that covered Tenro's body like armor, which reminded Kuwabara of the aura that Detective Matsudaira developed.

Reiatsu (Spirit pressure).

Tenro's aura was dense enough to become spirit pressure reminiscent of Bui from the Toguro Team. Or Yusuke whenever he unleashed his full power.

So this was the Chojin's secret weapon? If not the Chojin himself altogether?

The demon-slayer then grabbed the teenager's wrist and redirected the shuriken at Sano again, injuring him further. From there, he broke Kuwabara's hand altogether then grabbed him by the collar, declaring, "Secret Sword Two: GUREN KAINA! (CRIMSON LOTUS ARM!)"

Using his Mugen Jin to ignite the gunpowder-laced glove, the youkiri blasted Kuwabara with the force of a bomb.

The gunpowder-inside-the-glove trick that Shishio used on Kenshin was also used against Kazuma, with the explosion violently blowing him away. A hundred years ago, Makoto's hand was kept safe from the blast using a special metal gauntlet underneath the glove full of gunpowder that resisted the impact.

Tenro somehow ended up doing an even stronger version of the Guren Kaina that was imbued with the chaotic negative energy of the Chojin, which made the explosion strong enough to injure a human with the A-Class power level of Kuwabara.

Yahiko's power-suppressing aura didn't help in this case.

Tenro then shot the samurai ghost teen a look that chilled him to his "bones" or "spine". The youkiri then declared, "You will not drag me down to your level. Know your place, child."

However, while Tenro was distracted, the flickering spirit of Sanosuke stabbed the youkiri with hot molten metal of what was left of his sword in a spectacular display of sparks.

This was Sano's one chance of making a dent, so he had to make it count. However, as he attempted to punch Tenro's heart out, his hand ended up crushed with the youkiri's elbow block.

With a harrumph, Tenro proceeded to punch Sanosuke on the forehead, just like when Sano fought Shishio. "You never learn."

"I don't understand," murmured the Kaoru inside Botan's body. "Isn't Yahiko's aura supposed to suppress Tenro's powers too? Why is he still so strong!?"

She then noticed the unconscious Itsuki open his eyes and wake up, which led her to keep her guard up.

The black-and-blue Itsuki chuckled, tracing his finger over the scar Kuwabara had made on his face back when the Reikai Tantei faced off against Shinobu Sensui. "Y-You don't understand. This is him with his power held back."

"W-What do you mean? That's impossible!" Botan checked her Spirit Detector. "Oh no. His power is fluctuating between A-Level and S-Level when earlier it was just A-Level. That can't be! How powerful is he?"

Sneering, Itsuki said, "Who knows? Rumor has it he's about as powerful as one of the Former Three Kings—Mukuro, Yomi, and even the Late Raizen. He might even reach the mythical X-Level like Kurama did when he took hold of the Demon Sword."

Botan's face went pale blue as though unseen hands suddenly grabbed hold of her thin neck. "X-Level?!"

She remembered the event like it was yesterday.

The Spirit World went on high alert when Kurama went Class-X after wielding the Youtou Shinnoken (Demon Sword). They even called the entire Reikai Bouetai in. Not that it would've done them any good, since the Special Forces were composed of Class-A agents and Class-X was a level beyond Class-S.

She couldn't even fathom how strong an X-Level was since Kurama immediately rejected the Demon Sword, which transformed him back into his "human" self.

However, stronger than Yomi, Mukuro, or Raizen gave her a ballpark estimate of what they were dealing with. Someone as strong as or stronger than a Raizen-possessed Yusuke who ragdolled the mountain-destroying Sensui with ease.

All the same, Tenro stood victorious over the beaten figures of Sanosuke and Kuwabara.

"Will you become rams or sheep? Lions or feral street cats? Wolves or mongrel dogs? Can you evolve and turn into apex predators yourselves? It's natural selection. Kill or be killed. Make your choice."

***

The peaceful Tsurikake River had now become a war zone. A swamp in one part and a desert in another.

It was Baghdad. It was bedlam.

The 1,000,000% Toguro was there at the epicenter of the devastation. A nuke all his own. An unnatural force of nature.

An over-muscled demonized human even taller than his 100,000% version. A walking contradiction of chaos and order.

He had no skin now. He was all pure, red muscle and tendons pulsating and wriggling in every which way.

He also had six arms instead of two or four, with him towering even higher than before because he had to elongate his torso to cartoonish levels just to accommodate his extra pair of limbs.

Curious at how strong this Toguro was, Yusuke flipped the bird on Toguro with his other hand.

Yes, he had also stored another Fuck Gun on his other hand, with about the same amount of potential spiritual energy gathered for multiple weeks since he fired his first Fakku Gan at Feng Xinhai.

"FAKKU GAN!"

Again, Urameshi blasted all of his pent-up "Fuck You!" energy at Toguro by flipping him off, shooting the bolt of concentrated lightning that came out with the force of a shooting star.

Again, he outran the modified reserve Rei-Gan and came up from behind the six-armed insectoid Toguro with the intent of making sure he got hit by it.

He then attacked Toguro with both hands using the Rei-Gan and Shot Gun.

"DOUBLE-BARRELED SHOT GUN! DOUBLE BERRETTA REI-GAN!"

Those extra pair of hands on an even bigger and sturdier body made all the difference.

Two of six arms grabbed and held back the charged-for-weeks Rei-Gan. Another two of the arms parried and blocked all of Yusuke's energy-laden punches as well as the projectiles blasting through them.

This freed up the Million-Percent Toguro's two remaining hands that grabbed hold of Yusuke and pummeled him into submission.

The Younger Toguro utilized punches that carved the landscape. Made and destroyed mountains.

The kind of unnatural force of nature (as contradictory as it sounded) that could affect plate tectonics, weather patterns, or change the area forever, like in the case of Mt. St. Helens when it exploded or the nine ghost villages of France that remained wastelands to this day thanks to the Battle of Verdun in the First World War.  

If Yusuke's reiki-dense body weren't there to absorb the blows they would've shattered and sunk Okushiri right off of the map.

Even though Urameshi was breathing through his mouth, had lost several teeth, and ended up with a shattered jaw he couldn't close, he couldn't help but grin. Or at least do an open-mouthed smile.

"I'm beating you to the punch at every turn. So why is it...?" Toguro tilted his head to the side in askance. "Why do you have such a happy look on your face?"

Disturbingly, Yusuke's teeth grew back. They weren't supposed to do that but they did. Even accelerated human healing wouldn't allow the return of lost permanent teeth. All his bruises healed. All his broken bones mended themselves. His shut black eye's swelling subsided and went back to normal.

There he hung from Toguro's grip. Smiling. None the worse for wear save for torn clothes that couldn't restore themselves to their previous state.

"Come on, Toguro. You can do better than this, you son of a bitch! Gimme your best shot!"

Toguro then proceeded to smash Yusuke and his own heavenly body of a Fakku Gan together, which resulted in a mushroom cloud of pure destructive power.

Another atomic blast had hit Japan.

Toguro the Younger turned Urameshi into the atomic bomb he was afraid he had become.

***

Back at the Okushiri Pier, two things happened.

Botan, using the wealth of leftover negative energy that Kaoru purified earlier, again started healing the damage inflicted upon the available Reikai Senshi.

Kuwabara and Sanosuke stirred, as if shot by multiple doses of adrenalin.

Also, when the youkiri decided to deal with the shinigami herself to keep her from aiding her comrades, Yahiko himself confronted and attacked Tenro head on.

For all the good it did. Bless his ghostly heart.

"DOU GAMI...! (GOD ON EARTH!)" shouted Yahiko, hoping against hope it'd land on Tenro's head or sword or at least near him so that he'd get pelted by rocks and debris.

'So this is Shishio. The leader of the Juppon Gatana. Kenshin's most powerful rival,' the samurai spirit thought.

Tenro caught the reverse-edged blade between his fingers before it could make contact with him or the Mugen Jin. The God Hammer relied on recoil to give Yahiko enough space to consecutively strike something or someone three times fast in order to break their resistance and apply a zero-resistance strike.

No recoil meant the technique was neutralized.

Myojin's jaw dropped. "How...!?"

"So you're the brat who can neutralize spirit energy," said Tenro with narrowed eyes that traveled from Houji's unconscious form then all the way back to Yahiko.

Readjusting his grip of the sword tight with a gloved hand that smelled of gunpowder and negative spirit energy, Tenro again did the "GUREN KAINA!" on the blade.

The explosion blasted Myojin clear away from (presumably) Shishio, the shrapnel from his own spiritual construct of a sakabatou hitting him at the speed of bullets. His spirit fading and dissipating with pinpoints of energy.

''YAHIKO!" both Botan and Kaoru chorused in one unified body, fearing the worst.

However, the shards of Yahiko's shattered blade also penetrated Tenro's body, sealing his power further away from S-Level.

'What a problematic child this is.'

Myojin got up to his feet and charged with his broken reverse-edged blade, hoping to buy Sano and Kuwabara time. Buy Kenshin and Yusuke time as well.

He intended to do the Inga Gami on Tenro's head, only to revert to the Kamiya Kasshin Ryu ougi for Hadome and Hawatari when his opponent beat him to the punch and struck first with the Homura Dama.

However, as he defended against the downwards flaming strike with a crossed-wrist block, Tenro grappled with him and kept him from parrying the strike. "Do you want to know how your idol, Himura Battousai, died a century ago? Like this. Guren Kaina. Homura Dama."

After the explosion from the gunpowder happened, Tenro allowed the resulting fire to flare and roast the hapless ghost of Yahiko Myojin.

"AAAHH...!" screamed the burning Yahiko.

"YAHIKO!" shouted Sanosuke.

"BRAT!" yelled Kuwabara.

Tenro himself stood in the middle of the conflagration, but like in his confrontation with Hiei, he ended up none the worse for wear from the roaring bonfire.

"Too strong... He's too strong...!" gasped Yahiko. "Even after all this time, I'm still as weak as I've always been."

The bright yellow flames turned green then blue as Yahiko's form reverted to that of a hitodama (will-o'-the-wisp).

Meanwhile, Botan shrieked, fell on her knees, and covered her eyes with her hands.

"Who is stronger? A wolf in sheep's clothing or a sheep in wolf's clothing? Don't deny your true nature. Embrace what you really are. It's either you know your place or claw your way up the food chain. Evolve. Transform. Step up or step aside."

The entirety of Okushiri then started to rumble as Yahiko's neutralizing reiki ebbed away.

Like a dam that was about to break.

***

A nuke did damage in three stages.

It irradiated heat and light, it blasted everything to Kingdom Come, and it scattered radioactive materials around.

The bigger you went, the less relevant the radioactive materials became relative to the other effects as the heat irradiation had a much greater and more noticeable immediate effect. Effectively, when a nuke went off, the temperature of the resulting fireball could go up to millions of degrees, but it dissipated relatively quickly.

However, instead of having a repeat of Hiroshima and Nagasaki in 1993, Yusuke's dense aura (arguably going at reiatsu level at this point) allowed him to absorb most of the impact of his own Fakku Gan.

The explosion became a blockbuster level blast instead of an atomic bomb mushroom cloud.

Yusuke collapsed on the ground, taking the brunt of his own spirit energy.

Before him towered a behemoth of a demonized man. His exposed muscles bursting out of his skin. His six huge arms giving him an insect-like vibe.

This was Toguro using a million percent of his power. He had become the Demigod Asura, a six-armed demon of war and destruction.

However, even in the face of this absolute unit of a monster, something else from many miles away grabbed Urameshi's attention.

Over the horizon, he felt a suppressed Low S-Level power grow and pulse. Like a leaking and cracked dam ready to burst.

Once that dam finally burst forth, Yusuke broke all of his limits at once. Every last Spirit Cuff. Every last bit of hesitation he had from the Kugai curse placed upon him by Rando.

He caught even the Million-Percent Toguro by surprise at how fast his power level rose.

He summoned his version of the Sei Kou Ki, the golden aura serving as his barrier against Toguro's atomic punches.

His hair grew long and turned white for good measure before he proceeded to punch the Million-Percent Toguro a million times. A glowing golden punch for every percentage.

"SEI-KOU-DAN!" Yusuke cried, blasting Toguro with the Sei-Kou-Ki version of the Rei-Kou-Dan.

He had to. That dark presence in the distance sounded all of his internal alarms and red flags. His primitive flight-or-fight instinct activated.

As though feeling the rise in power from a distance spurred him into action more effectively than the golem before him that, quite frankly, took too long to get to S-Level and beyond.

Whichever Reikai Senshi was out there, they were fighting the final boss. The Chojin himself, even.

***

Botan rushed towards Yahiko's side, doing her best to heal his injured hitodama form. But the damage was extensive on his human soul, the light within his spirit fading away fast. "Hold on, Yahiko-kun! I got you! Everything's going to be fine!"

However, no matter how much spirit energy she used to heal Yahiko's damaged soul, it never healed. His hitodama continued to remain in its fireball state, flickering like a candle in the wind.

Kuwabara was the first to get up shakily on his feet, the Rei-Ken in his hand (also) flickering back and forth between its normal form and its Jigen Tou form.

"You talk too much, you bastard!" said the redhead, who attempted to create a portal to send the youkiri to space, only for Tenro to grab the teenager by his curly regent-style hair and put his face into the portal in an effort to suffocate him.

"What happened to Japan? Is this the best warriors that this new age can pony up? Pathetic," said Youkiri Tenro. "It's so sad. The United States of America turned the proud Empire of Japan into a whipped dog. An island full of losers and weirdoes."

Kuwabara ignited Tenro's glove with a small Rei-Ken on his free hand, which made it explode in the youkiri's face. Gasping for air, the redhead attempted another blind swing at the would-be dictator, only for him to end up stabbed in the lung.

He coughed blood as his eyes watered. His insides drowned in his own blood through internal bleeding.

"Sheep will always be sheep. Wolves will always be wolves. Lions will always be lions. A hitokiri will always be a hitokiri. A youkiri will always be youkiri. It's an aberration of nature to be one thing and claim to be another. If you want to become strong then change yourself for real. Defy or accept your fate. Become the predator or become the prey. It's up to you."

Ignoring the throbbing pain from his right fist that somehow trumped the ectoplasmic bleeding he got from the Rei-Shuriken, Sagara attempted a Futae no Kiwami and aimed it right into the chest of Shishio.

Or Tenro. Or the Chojin. Whoever he was or claimed to be.

Tenro tossed aside Kuwabara's quivering body like trash then blocked Sanosuke's punch with his own punch.

Last time, Sano broke his fist on Shishio's concrete face, his own Futae no Kiwami deflecting back to the bones of his hand. This time, his Douhle Extreme was enough to match Tenro's strength.

Only enough to match Tenro's strength though.

As Tenro again attempted to punch and crack Sanosuke's skull open, something unexpected happened.

"...SANJO NO KIWAMI!"

Sano blew Tenro's fist away with the Triple Extreme, which opened up his chest to a direct heart punch.

The coup de grace.

"FUTAE NO KIWAMI! DORYAAH...!"

Sanosuke landed the Futae no Kiwami right into Shishio's heart. Or Tenro's heart.

A second passed. The youkiri cackled.

"Congratulations. You're a little bit stronger now than before."

As the fading, transparent visage of Sanosuke let out a soundless scream, his pupils constricted into tiny dots on a white expanse, Tenro finally attacked the street fighter with his flame-producing weapon, its Homura Dama splitting Sano's head apart in a spectacular spray of ectoplasm.

"S-Sano..." choked out Kuwabara, his own vision fading along with Sanosuke's soul.

All that time, even in his will-o'-the-wisp form, the soul of Yahiko kept sealing the power of Youkiri Tenro. However, he couldn't contain the immense power of the Shishio reincarnation(?) any longer.

His soul finally succumbed, fading to black before shattering into a thousand pinpoints of light.

"Yahiko, no! No! NOOO!" cried Botan. "Dammit, come back! Oh no, what's going on? Why is everything going wrong?!"

Okushiri rumbled as the unleashed power of Tenro began to expand into a tall pillar of darkness and miasma. His jaki shot up into the sky, which gathered nimbus clouds all around them.

The localized quakes grew stronger and stronger. It felt like the world was about to split apart. This was the power of an Upper Class-S being that somehow ended up in the Human World.

He felt like power made flesh. A walking disaster area. A humanoid cyclone.

Tenro smirked as he surveyed the pier. He felt their presence. They were coming. He felt their power, anger, and desperation travel towards him like moths to his flame.

He could feel their strong presences, spirit energy, sword energy, and aura even from miles away.

One was on land, on foot, going faster than a cheetah. The other in the air, presumably ferried by one of Reikai's shinigami.

Who could they be?

First, there was the one half-demon, half-human mazoku descendant of Raizen, Makai's God of War, who was able to harness his demonic power and lineage. Raizen's true son. The Last Son of the Mazoku.

Yusuke Urameshi.

Second, there was the man who "defeated" Makoto Shishio to a suicidal kamikaze draw.  The Hitokiri Battousai who died and then became the Youkiri Battousai, the Guardian of the Demon Sword.

Kenshin Himura.

"Come forth. Show me the best and most powerful champions that this era has to offer. I'll defeat them all!" declared Tenro the Demon-Slayer to his upcoming opponents.

However, before Tenro knew it, his chest tightened. His heart stopped beating.

His negative energy wasn't able to heal the damage in time. He stood there, frozen. His time had stopped care of Sanosuke's efforts.

This happened due to the combination of the Futae no Kiwami and the shards of Yahiko's neutralizing reiki damaging his mortal heart. It kept him from manifesting the full breadth of his power that managed to take down even Hajime Saito.

The Kenshingumi's curse, if you would.

"Before challenging the champions of this era, watch out behind you. The past has a way of catching up with you, Shishio Makoto!"

Speaking of Saito, it was then and there that the headless corpse of Hajime Saito began moving on its own, with his one arm cradling his decapitated head.

As though he were the Headless Horseman. Or a Dullahan of Irish folklore.

That bastard. He was playing possum all this time!?

Tenro willed himself to move, but couldn't. He felt his left arm go numb. The shards of Yahiko's sakabatou might've reached all the way to his coronary arteries.

There was no telling how much cardiovascular damage Sanosuke's punch had done to his heart.

Dammit.

He began to sweat hard while clutching his chest. "Damn you, Saito Hajime."

"I've never seen you so sweaty and pathetic before," the head of Saito mocked before charging with his Gatotsu Ishiki from behind Tenro. "Then again, your sweat glands did get all burned up in your past life."

Instead of aiming at Tenro's head like with his encounter with Shishio, Saito instead aimed his sword right at Tenro's stopped heart while he was in the middle of a heart attack.

Appropriately enough, instead of being defeated by someone stronger than him, it was the desperate alliance of those weaker than Tenro that ultimately dragged him towards his ultimate defeat.

The ultimate irony.

"Go back to Hell, Shishio...!"

"No, I will make this world Hell and feel right at home!"

No. This was the same method Hajime used to "kill" Usui (temporarily). He took advantage of other people's hard work then opportunistically struck at the right time.

There was no way Youkiri Tenro would go down like a punk. Like Usui, of all people. An outsmarted weakling.

Tenro willed himself to move to block the strike.

His Homura Dama melted right through Saito's sword. Apparently, the Shinsengumi Captain was already using the last of his soul's strength to even make the strike, resulting in a vulnerable blade with barely any spirit energy to protect it.

Nevertheless, the rest of the hot blade plunged right into one of Tenro's lungs, spraying his blood all over the empty pier.

Saito smirked and closed his eyes. Instead of a solidified soul, Shishio really was reincarnated into an extra powerful human being. But a human being nonetheless. A mortal one that could be killed.

Tenro awaited the Gatotsu Zeroshiki that never came.

Alas, Saito already spent most of his energy fighting a full-powered X-Level Tenro earlier, with him sacrificing his very life force to just injure him now.

"I win again, Saito Hajime," hissed Tenro, coughing blood. "I survived your attack while you're already as good as dead. I can easily heal this damage and finish off the rest of the Reikai Senshi."

"That's my parting gift," said Saito, his own spirit fading. "You won't be able to reach X-Level in time now."

Before Tenro could wonder any further what Saito meant by his words, a gigaton punch shattered his face from out of the blue.

"Wha...?! GUAAAAH!!!"

Again, the wolf outfoxed him at every turn.

The youkiri realized that he'd just been punched by Raizen's "Son". The Mazoku Descendant. The hanyou (half-demon) that scared the great Enma Daio himself.

His brain sloshed inside his broken skull, leading to a concussion.

Any other impact from a weaker opponent wouldn't have even registered to Tenro. But a punch from an S-Level mazoku? That was a punch that could tear apart entire continents.

He also spotted from behind the long-haired, tattooed, and angry Mazoku Yusuke a warp portal that Kazuma Kuwabara probably made to shorten his best friend's travel time.

This was bad news.

His compromised heart and lungs hadn't recovered yet. Even though his energy levels were rising, his mortal damage kept him from manifesting his full power. He wasn't healing fast enough.

But this also excited him.

Tenro missed out on slaying Raizen—one of the greatest, oldest, and most powerful demons of the Demon World. Fighting his distant half-breed offspring was the next best thing to it.

With Yusuke's white hair and boundless energy, he himself looked to be at the cusp of achieving X-Level.

"Far more important than your power level, you've upended the natural order of things in both the Spirit World and the Demon World," said the gasping yet calm Tenro.

Yusuke picked up the pace, his nuclear-powered punches reaching speeds so impossibly, superhumanly fast that they came with their own eardrum-obliterating sonic booms.

However, the tough-as-nails Tenro absorbed every punch with his hard body and boundless jaki, so his mountain-obliterating punches "merely" made the pier shake and quake like a frightened child suffering domestic abuse.

"When Raizen died, you took over and found a way to keep the warring factions of Mukuro and Yomi from leading Makai into another millennia-long war for power."

Tenro gurgled but laughed with what sounded like a death rattle. Knocking at Hell's Gates with the sea of punches he had to wade through while punching and slashing at the elusive demon spawn in turn.

"You even helped expose the corruption within Reikai and had Koenma Daio depose his father, Enma Daio. Then you saved the Human World again from a Spirit World terrorist group. Imagine that."

The constant battery of kicks, punches, knees, elbows, and headbutts that barely gave Tenro any breathing room took their toll, making him cough and spew blood from many of his body's orifices, like his ears, eyes, nose, and mouth.

"The Chojin views you as a threat not because of your power level but instead of how you affect everyone and everything around you. You're a spanner in the works. Someone who can defy fate itself."

The threat of death made Tenro feel alive. His flight-or-fight instincts were on high alert.

After the thousands of demon hunts he'd participated in for the sake of turning his reincarnated yakuza boss self into someone worthy of housing Makoto Shishio's soul, this was the first time he actually, remotely felt threatened.

It was as he had imagined facing Yomi, Mukuro, or Raizen would've been like when they were still the Three Kings of Makai or at the peak of their power.

"We're cut from the same cloth, Urameshi Yusuke." Tenro sneered, wiping the blood from his nose. "I too exist to spite God. I defied my ultimate fate of death. From one lion to another, I will fight fate itself to write my own destiny. Just like you have."

"What the hell are you blathering on about?" said Yusuke, who kept up his endless barrage of Sei Kou Ki punches and kicks in order to pummel Tenro to submission.

Although he was winning the exchange, Toushin Yusuke's fists ended up aching and bleeding.

They might've even been broken by the dense thickness of Tenro's own reiatsu of negative energy serving as a barrier from inside and outside him, keeping his human body intact in spite of this mauling.

Regardless, the human-demon spawn had to finish Tenro off immediately.

Even though Urameshi was able to best Toguro by going all out, he could still feel his old enemy's presence. The Younger Toguro could still reemerge and possibly go beyond a million percent of his power. Perhaps a billion or a trillion even.

"Let's end this, Tenro. Or Shishio. Or Chojin. Whoever you are.  I'll finish you and your Shin Juppon Gatana off for good! SEI-GAN!"

A black-and-blue Tenro grinned as he felt a meteor-sized blast of purest Sei Kou Ki grow bigger and bigger from Yusuke's pointer finger. A miniature sun that glowed gold instead of bright blue.

This was the correct move. In order to finally penetrate through Tenro's reiatsu, Yusuke had to use his ultimate, ultimate move. A Rei-Gan powered by Sei-Kou-Ki shot by his white-haired demonic form.

However, the Chojin foresaw all this. This was why he gave (back) Tenro his original Mugen Jin.

When Yahiko still had his neutralizing reiki activated, the Mugen Jin could only be used the way it originally was made for, which was to create flames through the body fat and human oils it collected.

However, a hundred years later, the sword itself became a cursed sword with supernatural powers like the Youtou Shinnoken. It gained an extra property.

Without Yahiko's powers sealing its supernatural abilities away, it could absorb, steal, store, and release the spirit energy of others.

Thus, Tenro's Mugen Jin absorbed every last bit of the Sei-Gan from Mazoku Yusuke, only for him to do the third secret sword on him powered by Urameshi's own Sacred Light Spirit Energy.

"Secret Sword Three: KAGUZUCHI! (FIRE-BEARING SPIRIT GOD!)"

A fire tornado that mixed Tenro's demonic negative energy reiatsu with Yusuke's angelic sacred energy tossed the teenaged warhead around in a maelstrom of malcontent (since jaki was basically just energy derived from humanity's hatred and grudges).

If the mixture of volatile energy didn't kill the demonized Urameshi, then the centrifugal force of an F5 hurricane that would normally turn any normal human being into liquefied butter would.

"Hiten Mitsurugi Ryu Ougi: AMAKAKERU RYU NO HIRAMEKI! (HEAVENS GLIDING DRAGON FLASH!)"

The void created by the ultimate attack of the Hiten Mitsurugi Ryu destroyed the red, black, and gold wind funnel that had threatened to rage against Okushiri like a seasonal typhoon.

As a battered Yusuke fell from the sky, an erstwhile Kenshin jumped and caught him in midair before he could've crashed into one of the many cargo containers, if not outright fall into the hard concrete below.

They landed safely on ground zero of Yusuke's fight with Tenro, which was filled with craters and debris. From a distance, they could hear the blaring siren of many an ambulance.

"I came here as fast as I could with Ayame-dono's help," said Kenshin.

"K-Kenshin. S-Sorry. I-I almost had him, but he still had a trick up his sleeve," rasped Yusuke, who had transformed back to his human form, with most of his long hair burned away by Tenro's Kaguzuchi.

"Don't worry, Yusuke. I will finish off what you have started. What everyone had started, that I will," said Himura.

Tenro harrumphed, clutching his side. His chest still ached, his heart beating so fast it felt like it could explode. His brain throbbed and pounded inside his skull as well.

However, his adrenalin and his thrill for the fight coursed through his body, making him ignore every bit of pain he felt. He was about to pass the point of no return, after all.

In the corner of Kenshin's eye, he saw Botan stare at him with her own glistening eyes. He had heard the bad news directly from her care of the Spirit Communicator. She reported that the souls of Sanosuke, Yahiko, and Saito were no more. Also, Kuwabara was in critical condition.

They all fell against the hands of the man... the monster... before him. The wannabe dictator that he should've defeated a hundred years ago.

"I also look forward to fighting you again after all this time, Battousai. Come and die in my hands once more. The only law I follow is Survival of the Fittest. Only the strongest survive!"

"Survival of the Fittest, eh?" asked Kenshin. "Tell me, do you know what the first sign of human civilization is? How humanity became the most dominant species on earth?"

"...What?" asked Tenro in turn. "What are you talking about, Battousai?"

"I believe that the first sign of civilization is a femur that's been broken and then healed," said Himura. "In nature, a broken leg meant death. Kill or killed, right? Humans became the dominant species against stronger animals because of our cooperation and compassion. Helping someone else through difficulty is where civilization starts. We are at our best when we serve others. Be civilized."

"No. Nonsense," said Tenro. "Humanity stands on the shoulders of giants. Normal people are trash. Don't let the weak punish the strong for being strong while they themselves drown in their own mediocrity. Civilization or progress came about because of the strong. The exceptional. The best. The intellectuals. The Superman. The Overman. The Ubermensch. The Chojin."

"So you're the Chojin, huh?" said Himura. While it could be translated as "Overfiend", the name "Chojin" could also be translated as "Superman" or "Overman".

"The fates conspired against me and denied me my destiny to rule. I will write my own destiny now," said the youkiri to his fellow demon-slayer. Fellow manslayer, even.

"Regardless of what you say, both fate and time have already decided that you will not emerge victorious," Kenshin insisted. "You're destined to lose."

Tenro cackled. "Fate and time have chosen poorly, hence the pathetic state of Japan. The state of the world that's being led by sheep in wolves' clothing. Let me correct that century-old mistake. Even now, the weak are depending on your strength to protect them. Let the Ubermensch show the world what it's truly like to be strong! I will show them how to win!"

"It is neither the strongest of the species nor the most intelligent that survives. It is the one that is most adaptable to change," said Kenshin, quoting Charles Darwin himself as he fell into his battoujutsu stance.

Himura had to attack now, while Tenro was injured and recuperating. He would've attacked sooner, but he himself had barely recovered from battling Enishi.

As soon as the Shishio reincarnation healed and achieved X-Level, it was all over for the Reikai Senshi.

"AMAKAKERU RYU NO HIRAMEKI!"

"KAGUZUCHI!"

Kenshin and Tenro—or rather, Battousai and Shishio—finally clashed swords, the Youtou Shinnoken glowing bright-blue against the bright-red Mugen Jin. They picked up where they left off.

On one hand, Yusuke's leftover sacred energy powered up the Kaguzuchi and overwhelmed the initial strike of the Hirameki. On the other hand, the resulting void still formed, which multiplied the power of Kenshin's second strike many times over.

Tenro learned from his mistakes, understanding a century ago that there was a void formed after blocking the first strike of the Amakakeru Ryu no Hirameki. He sunk his stance low and pierced his Mugen Jin in the eye of the maelstrom so that his technique could be magnified in power instead of Kenshin's.

Kenshin hesitated, his soul remembering how Shishio snatched a draw from the jaws of defeat. He willed himself to slash upward regardless as an image of Kaoru filled his mind. Followed by all his friends and comrades.

He wished the same image had filled his mind a hundred years ago too. Then he wouldn't have died against Shishio.

Reality seemed to split from the lightspeed slash Kenshin did that clashed hard against Tenro's... no, Shishio's... red-hot cursed sword Mugen Jin.

On Kenshin's left was one timeline and on his right was another.

In one timeline, Kenshin found the strength and will to live to block Shishio's strike before he spontaneously combusted and died from overheating. Soon after, Shishio became the new King of Hell.

In another timeline, Shishio finished Battousai off then murdered Saito, Shinomori, Sagara, and the rest of the Oniwabanshu and Shinsengumi before forming a New Juppon Gatana and leading a coup d'etat against the Meiji Government. A second Bakumatsu. Afterwards, he died a despot. Japan's Genghis Khan.

In the timeline they were in, Kenshin and Shishio fought to a draw, with Kenshin dying along with Shishio in a blaze of glory. A hundred years after their fateful battle, Shishio ended up forming a New Juppon Gatana in order to lead a coup d'etat against the Spirit World.

In nearly all timelines, Shishio woke up from beyond the grave and ended up with an army of the undead, leading the charge towards world domination. Like a phoenix reborn from its own ashes. Again and again.

Even after his death, he was inevitable.

Would Kenshin falter like a hundred years ago or would he rise up and correct his century-old mistake? Which timeline would prevail?

A shining star of a whirling convergence of afterimages happened afterwards, followed by a huge explosion far into the distance. Right into the Sea of Japan.

A 7.8 earthquake then rocked the west coast of Hokkaido.  

On Monday, July 12, 1993, at 10:17 PM, a tsunami had formed off of the coast of Okushiri, leading to the loss of many lives.

To Be Continued...

Oh god, finally it's done. This took years to finish due to real-life things cropping up. Regardless, the arc that's been decades in the making is at last over.

Next up, the Spirit World deals with the aftermath of the failed Okushiri mission. Also, the first sign of civilization speech was taken from a quote from Anthropologist Margaret Mead.

【Draft】Youtou Shinnoken Chapter 58: Living Sin (Part 10)

The final chapter of the Okushiri Arc. Tenro finally makes an appearance.

The original source of this idea comes from Chad Yang. I continued his story idea found here.

The rest of the chapters of my Yuyu Hakusho and Rurouni Kenshin crossover fan fiction are available here and here. Enjoy.

About a hundred years or so ago...

In 1878, after fighting Kenshin "Battousai" Himura to a draw, Makoto Shishio died in a literal blaze of glory (through his own spontaneous combustion when his overheating body broke its limits) and went to Hell.

When he got there, he ended up right before the imposing gigantic figure of Enma Daio, who asked him, "What are you doing here, mortal? Go back to the Gates of Judgment in order to be judged."

Shishio then replied, "Get out of my throne. I'm the new King of Hell."

Chapter 58: Living Sin (Part 10)

***

Back at the Okushiri Military Base...

A shouting, crying Yahiko kneeled in front of Botan's unmoving body, seeing the huge hole in Botan's person. In the shinigami who somehow (he didn't quite understand it) was also his kendo master from a former life, Kaoru Kamiya.

Had he failed again? Like before, when Enishi Yukishiro...?

No. He would not let Kaoru down again. Not after what the Kenshingumi had been through right after Kenshin Himura's death...!

"Bloody Rain," said Yumi Komagata, who again made it rain blood mixed with what seemed like scalpels.

Right above the dark clouds filled with the scarlet liquid were Houji Sadojima's shikigami (familiars) that looked like grim reapers in and of themselves due to their ragged clothes, faceless voids for heads, and long scythes.

And beyond them was Gatekeeper Itsuki, who had a mini-gun at the ready in order to test the limits of a solidified ghost body before it became incorporeal once more. Knowing that gunpowder had no spirit energy to neutralize.

"DOU GAMI! (GOD ON EARTH!)" Yahiko's earth-shattering technique blasted away the razor-sharp squall and Itsuki's suppressive fire into oblivion, allowing him to dissipate the slicing rain bullets around him and the soul-crushing pressure of the borrowed aura of the Onmyouji (Occult Priest).

"Insolent welp...!" Houji said the thing.

"TEN GAMI! (GOD IN HEAVEN!)" Myojin shouted as he did a much more powerful version of the God on Earth that shot up high up into the heavens. Even the nimbus clouds parted from the strength of his slash.

This rocked and shook the military base like an earthquake while the Tokyo Samurai Descendant himself approached the Onmyouji like the resulting tsunami of such an earthquake.

"INGA GAMI! (KARMIC GOD!)"

It was this technique that suddenly turned the poisonous miasma of the Overfiend into something else. Something filled with positive energy and life-giving, nourishing soul power.

Sanosuke Sagara then noticed how the crimson, purple, and black miasma of jaki surrounding them started changing in color, texture, and volume. Flickering back and forth from a cool blue wave to a scarlet mess.

He then checked on Botan, only to gasp in surprise despite being a ghost that didn't need to breathe or have sudden oxygen intakes.

The hole in her chest caused by one of Itsuki's black holes had started healing. The jaki surrounding them, as Sano suspected, was slowly being purified into reiki, which in turn the ferry-girl used to heal herself.

Not only herself, actually. She shared the wealth by beaming the spirit energy she absorbed unto Kazuma Kuwabara and Sanosuke too. Replenishing their depleted spiritual power and increasing their health at the same time.

A full restore for all her allies, if you would.

'What's going on here? Is this Yahiko's doing? Or hers?'

It was actually both. Yahiko provided the reiki by purifying the jaki. Botan used that reiki to heal herself and the others while also powering them up, as though she was the Onmyouji of the Reikai Senshi (Spirit World Warriors).

Meanwhile, Kuwabara and Botan exchanged knowing glances.

They'd gone through this incident before. To be more specific, they witnessed firsthand Yusuke do the same thing Yahiko was attempting to do now.

It was when Urameshi got a hold of the Meikai Crystal and attempted to use it against the last Meikai God standing, Yakumo. The negative energy almost consumed him before his sheer willpower (and at the time hidden demonic lineage) turned the jaki into reiki instead.

Yahiko had decided it was easier to transform the Chojin's overwhelming negative energy to positive (spirit) energy instead of attempting to neutralize or seal it all at once. Break it down to its core components first, bit by bit.

The samurai boy then said, "BANZEN GAMI. (PERFECT GOD.)"

***

'Great fighters refuse to lose, but you refuse to win just to get back that feeling and exhilaration of conquering something greater than you. So what do you do now that you're in a world where nothing is greater than you?'

Those were the Younger Toguro's words even as Yusuke Urameshi effortlessly tanked through and walked down his offense while blasting him to nigh-oblivion with the Renshya Rei-Gan (Rapid-Fire Spirit Gun).

'What the hell was that supposed to mean?!' Yusuke thought.

Was Toguro Ototo right? Had Urameshi become too powerful? Was he holding back his power level in order to drag out fights he would've easily won, thus endangering the lives of those he protected with his great strength?

Ha. As if.

If that were true, he would've already hunted and killed the Chojin himself. He wasn't even the most powerful being in Makai (Demon World), let alone all three worlds. He was a level below the likes of Mukuro and Yomi as well as his deceased ancestor/father figure Raizen.

Not to mention Raizen's old comrades having power levels so high they could band together and conquer both the Human and Spirit Worlds if they so chose.

Those words truly did sound deep. They'd sound even deeper and more meaningful if said by a guy who wasn't getting his ass kicked care of him.

No, instead of it being a case of Yusuke growing too ridiculously powerful, it was rather a matter of Toguro remaining stagnant and weak.

The martial artist who belonged to the "baby boomer" generation might've been powerful for a demon not trapped in Makai and blocked off by the Spirit World Barrier, but he was a pissant compared to the likes of monsters Urameshi eventually faced in the Demon World Unification Tournament.

On top of all that, he didn't want to hear that nonsense from the King of Holding Back. The Emperor of Power Percentages.

"Rando's Kugai (World of Suffering) is a low-level technique by monks used to empathically feel the pain and suffering of others around them. The fact that you're still suffering from its effects isn't because of its curse but because of how you reacted to it."

Yusuke frowned. Indeed, for quite sometime since his fight with Rando, every punch he threw at his opponents, he also felt. For once, he found out what it was like to get punched by himself.

However, it also served as his training. The more he felt his own punches, the more resistant he became of his own power, thus raising his threshold of pain and his ability to take a punch. He could dish it out and take it.

He wasn't sure he could say the same about Toguro.

His ripcord muscles strained to their utmost, the Younger Toguro ended up having them ripped apart, crack, and shatter like pottery. The anabolism he used to grow his muscles to absurd sizes was completely wasted because he couldn't handle A-Level to S-Level blasts of power.

He'd give Toguro this. He did miss staking his life and limb to defeat an enemy, using all his strength to defend his friends and family.

He hadn't really done so lately. Not really. The last time he had a satisfying fight was with his match against Yomi.

Ever since then, his enemies mainly resorted to trickery reminiscent of Kido Asato freezing his movements with his shadow powers or Hiei kidnapping Keiko Yukimura.

All of them ended up as weaklings. Each and every one of them. To go against them with his full powers would be a waste of effort.

Like lighting a candle with a flamethrower or cutting grass with a chainsaw. Complete overkill.

Then again, wasn't this also the reason why Toguro, even though he was only B-Level, tended to hide his power level or only use a percentage of his power?

Huh.

***

Botan smiled in spite of herself. Or rather, her lips moved on their own and then said things not of her own volition due to her astral body's second inhabitant: Kaoru Kamiya.

"There it is. The Perfect God. That's Yahiko's answer to mastering the Mujinken."

A hundred years or so ago, Kaoru originally taught Yahiko the Tenchijinken (forethought-based techniques involving the prediction of an opponent's moves) while taught Yutaro Tsukayama the Mujinken (reflex-based techniques that reacted to whatever the opponent did in the heat of the moment) to fill in their respective weaknesses.

The two were actually more suited for each other's techniques, since Yahiko fought more off-the-cuff while Yutaro fought more methodically.

She intentionally sealed away the techniques that played to the two's strengths so that they could overcome their weaknesses more, believing that someday they'd figure out each other's ultimate attacks down the line anyway.

While the Inga Gami (Karmic God) showed Yahiko's version of methodical fighting, with him focusing hard enough on every strike to unleash the perfect counters without any wasted movement or energy, it was the Banzen Gami where he relied more on instinct instead of forethought showed his fullest potential.

He was more of a natural with the Perfect God than the Karmic God, while it was the opposite for the more thoughtful Yutaro (who now went by the name and identity of Natsuki Shinkai/Xinhai).

"INSECT!" said Houji, his wide eyes glowing red, his voice booming like thunder as he produced what seemed like an endless stream of shikigami. Only for Yahiko to seemingly cut and disintegrate them with a couple of reflexive waves of his sakabatou.

He wasn't even looking at the reapers as every reflexive slice of his blunt sword blew them apart and sent them to oblivion, his gaze aimed solely at Sadojima

The miasma of black jaki turned into white and blue shining reiki as Myojin passed by it. Once he reached Houji, their respective weapons clashed, the entire area split between the morning light colors from behind Yahiko and the pitch-black darkness from behind Sadojima.

It was like the clash of day and night, with the point of impact serving as their dusk or dawn. Twilight or daybreak.

To Houji's alarm, his scythe then started to crack and break. 'What the HELL is with this stupid kid!? I thought only the Youkiri Battousai and Urameshi Yusuke are our only real threats!  Chojin-sama, HELP!'

***

Instead of going down from the barrage of Rei-Gan, Toguro merely said, "Stop wasting energy," as though Yusuke left the light or electric fan turned on or something.

To Yusuke's surprise (or perhaps disappointment), the B-Class Toguro reacted to the Mega Spirit Gun bombardment the exact same way as he did during the Ankoku Bujutsukai (Dark Martial Arts Tournament): By attempting to charge at the growing spirit energy bullets and stop them with his bare hands and feet as well as his purely anabolic, hugely muscular body.

And just like that, it was over. With Toguro face down on the ground, his body shattered and torn from his exploded musculature. His body a tall, lean husk of its former self.

Another one bit the dust. Like the rest of Yusuke's revived enemies that came back stronger because of the Chojin but not quite strong enough to take him on.

To Yusuke's mild surprise, Toguro was still "alive".  Or this revived zombie version of himself made by Chojin's necromancer priest and his own personal Dr. Frankenstein was still moving.

The muscleman mercenary also said, "I'm merely at B-Level and I was able to push you this far? Your fighting senses have dulled, Urameshi Yusuke."

"Oh really? Well, I've discovered that at this point, no one could beat me but myself. You're welcome to prove me wrong, though," said Yusuke.

...Shit. Maybe Toguro and he were more alike than Urameshi realized. Right down to looking down on people who weren't on their level.

Toguro looked up at the night sky, which rekindled his memories. The Shichousei (Death Omen Star, also known as the Lifespan Star, Jumyoboshi, Alcor, or 80 Ursae Majoris) wasn't present near the Big Dipper.

Legend had it that when two warriors fought to the death under the Star of Death and it shone upon one of them, that person would die.

Was the star missing because he was already dead? Or because this wasn't much of a death match.

On the other hand, other Japanese myths and legends alleged that when one couldn't see the Lifespan Star, he'd pass away within a year. That was appropriate since Toguro himself was not alive anymore.

Fine. He'd turn it into a death match. Then, for once, he and Genkai would be looking at the same star. A fatal attraction to a fatalist's heavenly body.

Thusly, every broken bone from his body healed, but instead of going back to normal, they formed sharp calcified bone spurs that protruded right out of his rock-hared craggy body like horns or thorns.

He also got a power boost from the way his body decided to recover from his injuries, punching back a Chou Rei-Gan right into Yusuke's face before punching him as well with his bone spur claws on his fist right at the moment of impact, quadrupling its impact.

He just jumped from Class-B to Class-A in a mere second.

"Ooof!" The punch emptied the air from Yusuke's lungs.

"My former 100% has actually become less than 1% of my power, but for the sake of giving you a point of reference, I'll base my power increases on what was 100% of my power."

He grew about as big as his 100% of 100% form, perhaps even a little bigger, but this time the demonized behemoth's black hair turned as grey as steel along with the rest of his vascular body that was covered with huge bony protrusions.

"So you can call this form of mine me at 500% of my power."

Appropriately enough, the attack Yusuke used in response to Toguro's transformation was one he saw on T.V. From his favorite anime show, as a child of the 1980s, "Hokuto no Ken (Fist of the North Star)".

"HYAKU RETSU-KEN! (HUNDRED RENDING FISTS!)"

The Shichousei or Death Omen Star was, after all, also referenced by the same program.

Honestly, it was just Urameshi going ham on an opponent by randomly striking his heavy-handed punches at every opening available to him, with him naming the "technique" after the fact.

***

The devastation of the Okushiri Military base extended outward, with the pairs of Kazuma and Yumi as well as Sanosuke and Itsuki traveling eastward in a trail of devastation that followed Yahiko's own blaze of glory.

The green comet that was the Tokyo Samurai Descendant clashed and burned through the spherical cloud of miasma protecting Sadojima, like a shooting star entering the atmosphere.

The two pairs of enemies fought tooth and nail for proper positioning. The Reikai Senshi pushed the Chojin's forces back to protect Myojin from their interference.

Sanosuke punched through everything Itsuki threw at him through his hyperdimensional portals and busted portal gun, dodging the dense scattershot black holes and throwing pavement debris at the Gatekeeper in turn.  

Kazuma, meanwhile, fought from the distance, using his blade that can literally cut through anything and anywhere in order to turn every attempt of the wind vampire Yumi to blast tornadoes and energy-absorbing jaki apart.

Finally, Myojin himself struck the Chojin's (and at this point, it was the Chojin controlling the Onmyouji) scythe hard, the blade covered in miasma and dark energy.

The tides of battle then turned.

Using the jaki Kaoru purified into reiki, Yahiko's green aura became denser and denser, creating a white shining void at the center of his body that sucked the dark of the Chojin away. Acting like a reverse black hole or even "white" hole that absorbed all of the Overfiend's darkness into his pure light.

'This is it, Botan,' thought Kaoru "telepathically". 'This is the power of Mu (Void). The power of emptiness.'

'Emptiness...?' repeated the ferry-girl.

'Yes. A true martial artist is able to fight with instinct, freeing his mind of all thought and distractions, leading to a Zen State. Yahiko manifested this Zen State into his unique skill: Neutralizing spirit energy.'

A second later, all energy from everyone dissipated, and from there Houji's scythe shattered like glass as both he and Yahiko plummeted into the docks of the Okushiri Pier.  

The samurai spirit fell into Ryu Tsui Sen (Dragon Hammer Flash) stance and slammed Sadojima into one of the metal crates of the pier below them with an emphatic crash.  

"You stupid kid! I'll show you! ETERNAL...! Wait, what?! My powers are gone!"

Yumi Komagata attempted to do the Hi-Ougi (Hidden Art) of Vampire Martial Arts—a move stronger than the energy-sapping Blood Wind—but nothing of the sort manifested before her. Her aura, the energy she gathered from sucking many a soldier's blood, was now gone.

The same happened to Itsuki, who couldn't summon his Reverse-Man or escape into his pocket dimension any longer.

Yahiko's reiki had also went out, which normally was dangerous for a ghost but he somehow reached homeostasis with the way he absorbed and purified the Chojin's jaki.

His dense green aura had now completely neutralized the powers of everyone near him instead of merely mitigating their flow, including the now unconscious Onmyouji.

Like how no light could escape the event horizon of a black hole, not one shadow of the Chojin's dark energy could exist amidst the blinding white light of Yahiko's converging green spiritual aura.

However, as a consequence, even Yahiko's allies lost their powers as well, as though he was acting as the reverse version of the Onmyouji. Instead of boosting the powers of those in his vicinity, he nullified them.

Regardless, Sanosuke and Kuwabara immediately took advantage of the loss of powers from Itsuki and Yumi with their physical strength, with the former beating Itsuki to a pulp and Kuwabara breaking the umbrella and fan of Komagata before tackling and pinning her down.

"Give up, lady. You lost," said Kuwabara. "You can't cheat your way out of this one by resurrecting your goons every time we defeat them. The Onmyouji's down for the count."

Yahiko "heaved" a sigh of relief despite being a solidified ghost who didn't need to breathe. "It's finally over."

Botan giggled in glee. "We did it! You did it! The number one pupil of Kamiya Kasshin! I'm so proud of you, Yahiko!" The last part of that statement was Kaoru talking.  

Sano looked at his own bloody fists and winced. 'We've won, but why do I feel like it's not yet over? Like there's still something afoot.'

Even though the blood from his right fist wasn't his own but Itsuki's, it burned and ached something fierce. Like he broke it or something.

'What's going on? I have a bad feeling about this.'

Sanosuke's bad feeling then turned into reality.

***

At Class-A, Yusuke Urameshi's Hyaku Retsu-Ken would've turned the B-Plus Toguro into mince meat. Or roadkill.

At Class-S, his Hyaku Retsu-Ken would've turned mountains like Mt. Kannon, Mt. Kamui, and even Mt. Fuji into molehills, plains, or even outright trenches and canyons as deep as the United States of America's Grand Canyon.

Like he was a pint-sized Paul Bunyan.

The teenager harrumphed. "Really? 500%? Like I'm fighting 5 Toguros at the same time? So what? That's still nothing compared to the demons I've faced since defeating you, Toguro...!"

The bone-breaking punches cracked the shell of Toguro's chitinous muscle armor bit by bit. However, in turn, Toguro let his fists fly as well but in a more methodical manner.

Targeting his punches to Yusuke's openings rather than punching randomly. Using his martial arts experience to take down the stronger foe.  

His bony yet muscular fists pounded on Yusuke's smaller body, breaking bones here and there. He was approaching the same level as the one who killed him after every punch.

Yusuke's fists ached from every punch he did on the rock-solid body of Toguro, the multitude of Spirit Cuffs holding his power back also being pushed to their breaking point without him opening them up with his Jyu-Rei-Jyou Ante (Luminescent Spirit Ante) password.

The restraining cuffs and seals he placed upon himself were at their near breaking point from him merely flexing his immense power.

Thank goodness the likes of Yomi, Mukuro, Enki, and the rest of Raizen's friends (as well as Raizen himself when he was alive) put him in his place early on regarding what real power looked like, or else he'd be full of himself right about now.

The Toguro with chitinous bone spurs and keratinous tusks and horns all over his muscle-bound body ended up breaking each and every one of his thick, calcified bones from the impact of Yusuke's punches.

Toguro's bones rattled as micro-tears appeared all over his muscles and tendons. Despite this, he pushed forward. Like his older brother, he healed quickly, which notified Urameshi that he still had something in his sleeve.

"All right. Then how about this? TAKO NAGURI!"

The Octopus Assault—Yusuke's version of the Kuzu Ryu Sen (Nine-Dragon Flash) that hit 8 times instead of 9 times in an instant—hammered the horned gray body of the zombified and demonized Toguro before he could get the chance to stab, gore, or spear Yusuke with his many protruding bone spurs.

Urameshi once heard that it took either 23,034 slaps to cook or a slap traveling at 1,665.65 meters per second to cook a chicken.

He wasn't sure about the math, but he cooked Toguro's goose at a rate of 8-16 punches a second with every punch traveling at 1,000-2,000 meters per second, so it would've took about 20 minutes of non-stop Tako Naguri to get to around 20,000 punches or 2,500 super-powered Tako Naguri.

Or he would've cooked/burned 20,000 whole chickens at around the time it took to cook a chicken in the oven.

However, it was at the second minute that Urameshi broke his hand. He hit a hard shell reminiscent of the healing turtle shell that was Usui's shield.

From the pile of minced meat, torn muscle cords, and viscera emerged yet another Toguro.

What stood before him wasn't the spurred behemoth Toguro but instead a fully armored Toguro, with every inch of his body covered in craggy white bone.

As though his shattered bones healed wrong and ended up calcifying right on top of his pulsating muscles. The parts where his joints were, he simply muscled to existence, breaking the calcified armor in sections.

"This is 1,000% of my power. 100 times the power of my 100% self."

It also made him look like a white lobster man, thought Yusuke in chagrin.

***

At the Okushiri Pier, around 9:47 PM...

The mangled remains of a man landed right in front of Reikai's finest from out of the shadows of the dark harbor.

The Reikai Senshi (and their accompanying shinigami) then felt goose bumps form at the napes of their necks, including the ghostly ones that didn't even have tangible skin, blood, or hair to make such a sensation possible.

Even Itsuki, whom Sano beat from pillar to post with bare-knuckle fisticuffs, looked none the worse for wear compared to the person before them.

He was bathed in blood and his torn clothes were dyed crimson because of it. He looked like he'd been ravaged by a pack of wolves.

The only thing recognizable about him was that he was male.  Probably.

Sanosuke was the first one to try and poke at the figure to see who it was. If he had a ten-foot pole, he'd prod the man with it. As it was, thanks to Yahiko manifesting his full neutralization powers, Sano couldn't even summon one zanbatou from the ether.

The street fighter then stumbled back, which made Kazuma ask, "What's wrong? Who is it? Is that one of the Chojin's Shin Ju or whatever?"

Botan gulped, hoping against hope that the man before them was the injured body of one of the New Ten Swords instead of one of the Spirit World Warriors.

Before Sano could answer, someone else answered for him.

"That's what remains of Hajime Saito. The former captain of the Shinsengumi's Third Unit."

"...What? Who said that?" asked Yahiko.

The Reikai Tantei, the shinigami, and the Kenshingumi then turned in time to see the silhouette of a pony-tailed person from the distance.

There stood a human(?) of about S-Level power with sleeked-back hair, a lengthy ponytail, and a half-undone kimono that showed off his rippling swimmer's muscles on his long build.

As realization dawned on them one by one, their mouths went agape, practically unhinged from their upper jaw.

The blood drained from Kuwabara's face while the three spiritual beings' faces (Botan/Kaoru, Sano, and Yahiko) looked more transparent than usual.

The ghosts all looked like they'd seen a ghost, forgetting they were ghosts themselves. Gasping for air they couldn't breathe anymore.

Even Kuwabara, who was alive, looked like he'd seen a ghost himself or even turned into one.

The man, who himself was a bloody mess with stabs and cuts at every inch of his body, held something in his arms.

It was his trophy. His prize after a hard day's battle.

It was the head of his enemy. It was the head of Hajime Saito.

Botan screamed. Or rather, Kaoru did.

The Kamiya Kasshin Master couldn't believe that Kenshin's greatest rival who was so famous he became a Japanese historical figure later on, had been defeated.

On the other hand, Botan, through centuries of being a death goddess, had seen worse things before, so she was desensitized enough to not scream. Her own feeling of dread was around the same level as Kaoru's, though.

The pony-tailed assassin then took one look at the Kenshingumi sans Kenshin and their shinigami babysitter and sighed.

"Oh, no one but weaklings left? Pathetic. Imagine, after such a delicious meal, I'm left with leftovers and expired food."

The new arrival then placed Saito's head beside the rest of his body. Almost reverently. "Rest in peace, Saito Hajime. You were truly a worthy rival. I acknowledge you."

"You killed Officer Fujita! You BASTARD!" screamed Kuwabara, a knife-sized Rei-Ken ablaze with reiki and righteous indignation in his grip.

Kazuma would've produced a full-length Jigen Tou with the rage he felt, but Yahiko's neutralizing presence kept his powers in check.

"Wait. Boke (Fool), he's...!" Sano trailed off, moving in front of Kuwabara to block him from doing anything hasty.

'If anyone's going to do something hasty, it was going to be me!' thought Sagara.

"Who are you?" demanded Yahiko as he pointed his sakabatou at the stranger.

"I'm Youkiri Tenro (Tenro the Demon-Slayer). Remember that name before I send you back to Heaven."

***

Yusuke quickly checked his Spirit Detector. Toguro was now at A-Level with his Bone Armor form. Around the same power level as the most powerful members of the Reikai Tokubetsu Bouetai (Spirit World Special Forces).

This turn of events definitely piqued his interest. Somewhat. Maybe this time, he'd get the battle he so craved from this new version of Toguro since being defeated by Yomi in the Makai Tournament.

However, the extra layer of bone armor made it harder for Yusuke to break apart Toguro's muscle armor with mere punches, no matter what velocity he reached.

Also, in turn, the Class-A Toguro Ototo pummeled and stabbed Yusuke in turn with earth-shattering strikes from his bony fists, horns, and claws as well as shattered pieces of his bone armor that kept calcifying and growing over and over. Layer by layer. Like samurai armor or shingles on the roof.

Stubbornly, the bloody and bruised Yusuke kept on punching the armored demon to push him away and give him breathing room.

The bony yet muscle-bound contradiction of a monster that looked ridiculously gigantic yet unencumbered by his musculature having an extra layer of armor unto him, turning him into a veritable tank with the speed of a Mack truck. He even hit like a truck.

Alas, as his wounds healed in Toguro Ani fashion, Urameshi realized that he had long ago surpassed the version of him that could get killed by being hit by a car. Or a truck. Or a tank. Or perhaps even a nuclear warhead. Maybe.

"Rei-Kou-Dan (Spirit Light Wave Bullet)."

One of his Spirit Cuffs broke as he put his hip into his punches and imbued his fists with actual spiritual power. They were already harder than steel because of the spirit energy contained within his body. Put when he emanates reiki from inside and outside himself, his punches also become explosive.

One reiki-imbued punch was all it took for him to crack the bone armor of Toguro at 1,000%. However, he wasn't done.

Perhaps he might have gone overboard, but he decided to punch Toguro 20,000 times in 3 minutes rather than 20 minutes. But it sure felt like 20 minutes.

Also, these weren't just physical punches. His fists were on fire with spirit energy this time. 20,000 Rei-Kou-Dan blasts, to be exact.

Every supersonic punch had the impact of a blockbuster bomb, with it breaking the sound barrier and sending extra shockwaves to Toguro and all. Perhaps even more explosive than that.

Perhaps he'd become a teenaged warhead himself.

However, out of the mangled mess of bone armor emerged yet another Toguro. The armor that should've served as his coffin ended up becoming his cocoon for his newest metamorphosis. Which, to Yusuke's surprise, made him breathe a sigh in relief.

He could still push himself even further.

Was this excited feeling what Toguro felt when, just a few years prior, Yusuke was able to withstand the might of 80% of his power when he killed Genkai in cold blood?

Regardless, a bronze-skinned, taller, and four-armed Toguro emerged from all that mush and burnt flesh he'd become earlier, impossibly towering even higher over Yusuke. His current form made his former seven-foot form look normal-sized in comparison.

His muscles were like taut steel cords now, like those used in heavy-duty tires and conveyer belts. Perhaps even harder. They were definitely harder than the pieces of thick calcified bone armor that they crushed like egg shells with a simple collective body flex.

"This is 100,000% of my power. This is what fighting 10,000 clones of my 100% self looks like."

Yusuke thought for a second what Toguro meant by that, only for him to test the theory out with an additional 20,000 Rei-Kou-Dan blasts in one minute.

20,000 palm blocks later and Urameshi now had a better idea of what his nemesis meant, followed by 20,000 counterpunches in between those blocks. All in a minute's time.

'100,000% Toguro? He didn't even bother going to 10,000%? Jeez!' Urameshi thought as he got hit with a two-armed lariat that dragged his body across the landscape and river like a cow or trailer home in a tornado.

This was it. This was the A-Plus version of Toguro.

Yusuke couldn't even hide the grin from his face even as this newest form of Toguro beat him to the punch every time.

Toguro at 100,000% had even tighter and tauter musculature with enough strength and torque behind in them to break apart from his bone cocoon or calcified eggshell. His ripcord muscles could handle punching velocities similar or even faster than Yusuke's.

It also didn't help that Toguro now had a body that could accommodate four arms, thus giving him twice the hand speed and arm speed due to his literal extra limbs.

***

"...SHISHIO!" screamed Sanosuke at Tenro, his blood (ectoplasm) boiling. His right fist, whom Makoto Shishio broke, pulsating like a second heart.

Even though he wasn't wearing his bandages and his skin wasn't burned to a crisp, Sano could recognize that voice and that demeanor anywhere.

''Shishio?' thought Kuwabara. So this is the man who founded the original Juppon Gatana? Kenshin's greatest rival? The man who ultimately led to the demise of the samurai spirit? The man who might actually be the alter ego of the Chojin himself?

The guy who not only pushed Hiei to his limits, but also possibly two of the Demon World's three kings, Yomi and Mukuro?

Before they knew it, they were suddenly faced with the final boss of the game.

The fighting spirit of Sano rose high enough for him to defy the nullifying presence of Yahiko and form half of a zanbatou in his hands, which he swung at the (presumably) non-burned version or reincarnation of the ex-hitokiri and Meiji rebel known as Shishio.

With one swing of Tenro's Mugen Jin (Unlimited Blade) sword, Sagara's suspicions were confirmed.

"Secret Sword One: HOMURA DAMA!"

Shishio's signature Homura Dama (Burning Soul) technique where his sword burst into flame clashed hard against the 6-foot (normally 12-foot) horse-chopping sword, smelting it in the process like a blacksmith's forge in a shower of sparks.

"A weakling like usual, Sagara Sanosuke," sneered Tenro. "It's been a while, though."

"I don't understand. Wasn't Shishio supposed to look like a mummy or something? He's some guy who was burnt to a crisp and covered in bandages!" said Kazuma.

Sano answered, "Yeah, but obviously it's been 100 years. He must've found a way to get a new body, ended up with a solidified soul, or he got reincarnated as this Tenro clown."

Myojin gulped. He considered deactivating his powers to allow either Kuwabara or Sanosuke to attack the youkiri.

However, if Tenro was this powerful with his spiritual power nullified, how much more powerful could he get when Yahiko's powers ceased working?

The disheveled Yumi then cackled in the background, the hole in her chest throbbing with a ghostly heart whom the man before her had stolen from her.

"It's about time you got here, Tenro. What took you so long? Don't tell me the Miburo (Mibu's Wolf) gave you all that you can handle and then some."

Tenro harrumphed. "Perish the thought, Yumi. I merely gave my respects first to the Shinsengumi in the Battle of Hakodate Monument, and guess who I also found there? That's right, our favorite Shinsengumi Captain, Saito Hajime."

'Hakodate?!' thought Yahiko. 'That's four hours away from Okushiri! All the way on the other side of Hokkaido, at that!'

Sanosuke himself snarled at Tenro, his fist burning with pain and fire, as though it remembered how Makoto had shattered it when they'd faced each other back at Mt. Hiei.

'Hakodate is the place that served as the Shinsengumi's last stand. What was Saito doing there? Was he paying his respects to his squad? It's not like him to be so sentimental.'

The street fighter spared a glance at the remains of Saito. Unbelievable. Just earlier, he pushed several of the Shin Juppon Gatana to their limits, and now he ended up as dead as the rest of the Shinsengumi?

Well, he was already originally dead and buried in the first place, but this time around he got killed off for real by Shishio. Or Tenro, which was probably the reincarnation of Shishio (the same way Aoshi was reincarnated as a copper).

Kuwabara turned towards Yahiko and said, "Kid, turn off your powers! I'm going to face off with the final boss one-on-one!"

"But...!" the ghost kid trailed off before Botan filled in the rest.

"Kuwabara-kun, he can't. He's the only one sealing Tenro's immense power. If he was able to do that to Saito, imagine what he could do to us! Let Yahiko seal his power for now until either Kenshin or Yusuke arrives!" said the ferry-girl.

"I DON'T CARE!" shouted Kuwabara. "Let us face him at his full strength while we're also at full strength! As a real man, I won't back down!"

Tenro smirked. "Fine. If you're not bluffing then come at me. In this world and beyond it, the same rules of nature apply. Only the strongest survive and the weak serve as food for the strong."

Sano's eyes narrowed. He was definitely sure this was Shishio before him now. That was totally a Shishio line. 'It's now or never. We just have to keep him here until either Kenshin or that gangster best friend of Boke arrives!'

***

"REI-KOU-DAN!" shouted Urameshi, his Spirit Wave Light Bullets bursting through his fist like bolts of lightning from a Railgun.

The 100,000% Toguro blocked the punch with his elbow, shattering Yusuke's hand bones in the process. "Is this the power of an S-Level? Don't make me laugh. Me at 100,000% of my power is enough for you."

Toguro then grabbed hold of Urameshi's limbs with all four of his arms in a bid to tear the teenager apart literally from limb to limb.

Yusuke considered Toguro's statement for a second and then said, "Fuck that," before flipping the four-armed monster off with his right hand.

The mere idea that someone like Feng Xinhai or The "Beautiful" Suzuki was more powerful than Toguro just didn't sit well with Urameshi. At all.

The middle finger he raised at the 100,000% Toguro then flowed with energy he'd been saving for a special occasion.

Yusuke discovered that he could actually save and store his energy as a reserve or extra Spirit Gun blast for use in case of emergencies since it usually took forever and a day to charge his Rei-Gan.

Also, in order for him to not mistakenly fire off his reserve Rei-Gan, he had this bullet stored in his middle finger. This was how his technique that he developed when facing off against the S-Level Xinhai.

This was his "Fuck You!" Gun. Also known as the "FAKKU GAN! (FUCK GUN!)"

The 100,000% Toguro let go of Yusuke to bring distance between him and the spiritual projectile then punted the Fuck Gun towards the teenager.

However, by instinct borne from his hundreds of fights against spiritually powerful humans and demons, Yusuke jumped away from the Fakku Gan, grabbed Toguro by the ankle, dragged him towards the ball of plasma fire, and then threw him back into its path.

From there, as the 100,000% Toguro braced himself for impact, Urameshi emerged from behind him. Attacking him from the rear for good measure.

Toguro was now between a rock and a hard place. Or between a demon and his energy blast.

"REI-KOU-DAN! SHOT GUN!" screamed the half-demon prince.

While the Fakku Gan blasted and disintegrated the giant from the front, Yusuke attacked with his Spirit Light Wave Bullets and reiki scattershot from behind, which kept even the four-armed monstrosity from defending himself from upcoming impacts surrounding him.

The charged-up blasts of energy in particle and wave forms bore on Toguro like plasma tides or a solar wind. An endless series of reiki tidal waves from the ocean of Urameshi's power.

Thanks to the extra pressure brought about by his stored energy blast from many weeks ago, Yusuke's Rei-Kou-Dan was able to strike through this time, with him ripping the steel cord muscles of Toguro apart as they got softened by the comet of energy that cooked him alive.

Then, as Yusuke had hoped deep in his unbeating heart, the mangled Toguro changed form yet again.

The same heart that Shinobu Sensui pierced so that it'd stop beating felt like it started beating yet again in anticipation. In excitement. In nostalgia, even.

Toguro still had more forms and powers up his sleeve. Just like old times.

And from there, out of the ashes and melted muscle of the 100,000% Toguro came forth One Million Percent Toguro.

"One Million Percent. This is me at One Million Percent of my power, Urameshi Yusuke."

***

Kuwabara and Sanosuke attacked Tenro at the same time while Yahiko struggled on the spot to focus all his neutralizing powers on the Shishio reincarnation(?) alone.

Tenro frowned. His aura of jaki became fainter despite him doing damage to the Tokyo Samurai Descendant.

'Hmmm. The Shin Ju warned me about this. Even Toguro Ani couldn't heal properly thanks to this kid's neutralizing reiki.'

Botan checked her Spirit Detector again. Hope sprung in her heart. 'Yes! Tenro's power level went down to A-Level. He's still on the cusp of S-Level, but at least he's not as powerful as someone like Sensui and Xinhai! We have a chance!'

As Kuwabara and Sanosuke awoke, their energy levels went higher and higher, their auras flaring with spiritual might that was boosted by Botan's healing powers.

"JIGEN TOU!" screamed Kazuma, summoning his Dimension Sword.

"ZANBATOU!" shouted Sanosuke, producing his 12-foot long Horse-Chopping Sword.

"How appropriate. Isn't this just a reflection of today's society? The weak are using their great numbers to suppress their betters, not realizing that without the strong to lead them or the will to become strong themselves, they will end up extinct."

"SHADDAP! I don't know who you are, but all's fair in love and war," declared Kuwabara.

"Not all men are created equal. Like in the Animal Kingdom, some men are simply better than others. Equal opportunity doesn't guarantee equal results. Forcing equal results in an aberration of nature, like forcing animals to become like men, the pinnacle of evolution."

Tenro used his bare hand to grab hold of Kuwabara's Dimension Sword and used his other hand with a sword to block the full-length zanbatou coming at him with his saw-like Mugen Jin.

"Ganging up on the strong can lead to the survival of the weak temporarily. However, their own weakness will sort them out. Their celebration of mediocrity will make them food for other apex predators or any of them who decide to become rams instead of sheep."

The Youkiri then broke the Jigen Tou apart like it was made of chalk and stabbed Sanosuke's chest with it while also melting his second attempt at a half-zanbatou with his Mugen Jin's Homura Dama.

"Regardless, it is better to live one day as a lion than 100 years as a sheep. These are... THE RULES OF NATURE!"

"AUGH!" grunted Sanosuke, his recently recovered soul flickering in and out of existence, his chest spewing ectoplasm, and his aura dissipating into pinpoints of light like a disturbed nest of bioluminescent fireflies.

He felt the light inside him slowly fade all the while.

"Bastard...!" said Kazuma, who repurposed the broken shards of his Jigen Tou and shot it pointblank at Youkiri Tenro, turning them into "REI-SHURIKEN!"

He should've hit him with the projectiles from a distance, though. The first few blades bounced off of the intense jaki of Tenro, which reminded Kuwabara of the aura that Detective Matsudaira developed.

Reiatsu (Spirit pressure). Tenro's aura was dense enough to become spirit pressure reminiscent of Bui from the Toguro Team. Or Yusuke when he unleashed his full power nowadays.

So this was the Chojin's secret weapon? If not the Chojin himself altogether?

The demon-slayer then grabbed of the teenagers wrist and redirected the shuriken at Sano again. From there, he broke Kuwabara's hand then grabbed him by the collar, declaring, "Secret Sword Two: GUREN KAINA! (CRIMSON LOTUS ARM!)"

Using his Mugen Jin to ignite the gunpowder-laced glove, the youkiri blasted Kuwabara with the force of the bomb.

The gunpowder inside the glove trick that Shishio used on Kenshin was also used against Kazuma, with the explosion blowing him clear off. Makoto's hand was kept safe from the explosion using a special metal gauntlet underneath the glove full of gunpowder that resisted the impact.

Tenro somehow ended up doing an even stronger version of the Guren Kaina that was imbued with the chaotic negative energy of Tenro, which made the explosion strong enough to injure a human with the power level of Kuwabara. Yahiko's power-suppressing aura didn't help.

Tenro then shot Yahiko a look that chilled him to his "bones" or "spine". The youkiri said, "You will not drag me down to your level. Know your place, child."

However, while Tenro was preoccupied, the flickering spirit of Sanosuke stabbed the youkiri with hot molten metal or what was left of his sword in a spectacular display of sparks.

This was Sano's one chance of making a dent, so he had to make it count.

However, as he attempted to punch Tenro's heart out, his hand ended up crushed with the youkiri's elbow block.

With a harrumph, Tenro proceeded to punch Sanosuke on the forehead, just like when Sano fought Shishio. "You never learn."

"I don't understand," murmured the Kaoru inside Botan's body. "Isn't Yahiko's aura supposed to suppress Tenro's powers too? Why is he still so strong!?"

She then noticed Gatekeeper Itsuki waking up, which led her to keep her guard up.

The black-and-blue Itsuki chuckled, tracing his finger over the scar Kuwabara had made on his face back when they faced off against Shinobu Sensui. "Y-You don't understand. This is him with his power held back."

"W-What do you mean? That's impossible!" Botan checked her Spirit Detector. "His power is fluctuating between A-Level and S-Level. That can't be! How powerful is he?"

Sneering, Itsuki said, "Who knows? Rumor has it he's about as powerful as one of the Former Three Kings—Mukuro, Yomi, and even the Late Raizen. He might even reach the mythical X-Level like Kurama did when he took hold of the Demon Sword."

Botan's face went pale blue as though she was being choked. "X-Level?!"

She remembered the event like it was yesterday.

The Spirit World went on high alert when Kurama went Class-X after wielding the Youtou Shinnoken (Demon Sword). They even called the entire Reikai Bouetai in. Not that it would've done them any good, since the Special Forces were composed of Class-A agents and Class-X was a level beyond Class-S.

She couldn't even fathom how strong an X-Level was since Kurama immediately rejected the Demon Sword transforming him back into his youko self.

However, stronger than Yomi, Mukuro, or Raizen gave her a ballpark estimate of what they were dealing with. Someone as strong as or stronger than a Raizen-possessed Yusuke who ragdolled the mountain-destroying Sensui with ease.

All the same, Tenro stood victorious over the beaten figures of Sanosuke and Kuwabara.

"Will you become rams or sheep? Lions or stray cats? Wolves or mongrel dogs? Can you evolve and turn into apex predators yourselves? It's natural selection. Kill or be killed. Make your choice."

***

The peaceful Tsurikake River had now become a war zone. A swamp in one part and a desert in another.

It was Baghdad. It was bedlam.

The 1,000,000% Toguro was there at the epicenter of the devastation. A nuke all his own. An unnatural force of nature.

An over-muscled demonized human even taller than his 100,000% version. A walking contradiction of chaos and order.

He had no skin now. He was all pure, red muscle and tendons pulsating and wriggling in every which way.

He also had six arms instead of two, with him towering even higher than before because he had to elongate his torso to cartoonish levels just to accommodate his extra pair of hands and limbs.

Curious at how strong this Toguro was, Yusuke flipped the bird on Toguro with his other hand.

Yes, he also stored another Fuck Gun on his other hand, with about the same amount of potential spiritual energy gathered for weeks' on end since he fired his first Fakku Gan at Feng Xinhai.

"FAKKU GAN!"

Again, Urameshi blasted all of his pent-up "Fuck You!" energy at Toguro by flipping him off, shooting the bolt of concentrated lightning that came out with the force of a shooting star.

Again, he outran the modified Rei-Gan and came up from behind the six-armed insectoid Toguro with the intent of making sure he got hit by the Fakku Gan.

He then attacked Toguro with both hands using the Rei-Gan and Shot Gun.

"DOUBLE-BARRELED SHOT GUN! DOUBLE BERRETTA REI-GAN!"

Those extra pair of hands on an even bigger and sturdier body made all the difference.

Two of six arms grabbed and held back the charged-for-weeks Rei-Gan. Another two of the arms parried and blocked all of Yusuke's energy-laden punches as well as the projectiles blasting through them.

This freed up the Million-Percent Toguro's two remaining hands that grabbed hold of Yusuke and pummeled him into submission.

The Younger Toguro used punches that carved the landscape. Made and destroyed mountains.

The kind of unnatural force of nature (as contradictory as it sounds) that could affect plate tectonics, weather patterns, or change the area forever, like in the case of Mt. St. Helens when it exploded or the nine ghost villages of France that remain wastelands to this day thanks to the Battle of Verdun in the First World War.  

If Yusuke weren't here to absorb the blows they would've shattered and sunk Okushiri right off of the map.

Even though Urameshi was breathing through his mouth, had lost teeth, and ended up with a shattered jaw he couldn't close, he couldn't help but grin. Or at least do an open-mouthed smile.

"I'm beating you to the punch at every turn. So why is it...?" Toguro tilted his head to the side in askance. "Why do you have such a happy look on your face?"

Disturbingly, Yusuke's teeth grew back. They weren't supposed to but they did. Even accelerated human healing wouldn't allow the return of lost permanent teeth. All his bruises healed. All his broken bones mended themselves. His shut black eye's swelling subsided and went back to normal.

There he hung from Toguro's grip. Smiling. None the worse for wear.

"Come on, Toguro. You can do better than this, you son of a bitch! Gimme your best shot!"

Toguro then proceeded to smash Yusuke and his own heavenly body of a Fakku Gan together, which resulted in a mushroom cloud of pure destructive power.

Another atomic blast had hit Japan.

Toguro the Younger turned Urameshi into the atomic bomb he was afraid he had become.

***

Back at the Okushiri Pier, two things happened.

Botan, using the wealth of leftover negative energy that Kaoru purified earlier, again started shot reiki to heal the damage inflicted upon the available Reikai Senshi.

Kuwabara and Sanosuke stirred, as if shot by doses of adrenalin.

Also, when the youkiri made the move to deal with the shinigami herself to keep her from aiding her comrades, Yahiko himself confronted and attacked Tenro head on.

For all the good it did. Bless his ghostly heart.

"DOU GAMI...! (GOD ON EARTH!)" shouted Yahiko, hoping against hope it'd land on Tenro's head or at least near him so that he'd be pelted by rocks and debris.

'This is Shishio. The leader of the Juppon Gatana. Kenshin's most powerful rival,' the samurai spirit thought.

Tenro caught the reverse-edged blade between his fingers before it could make contact with his Mugen Jin. The God Hammer relied on recoil to give Yahiko enough space to consecutively strike something or someone three times fast in order to break their resistance and apply a zero-resistance strike.

No recoil meant the sword's three strikes were neutralized.

Myojin's jaw dropped. "How...!?"

"So you're the brat who can neutralize spirit energy," said Tenro with narrowed eyes that traveled from Houji's unconscious form then all the way back to Yahiko.

Readjusting his grip of the sword tight with a gloved hand that smelled of gunpowder and negative spirit energy, Tenro again did the "GUREN KAINA!" on the blade.

The explosion blasted Myojin clear away from (presumably) Shishio, the shrapnel from his own spiritual construct of a sakabatou hitting him as well like bullets. His spirit fading and dissipating with pinpoints of energy.

''YAHIKO!" both Botan and Kaoru chorused in one body, fearing the worst.

The shards of Yahiko's blade penetrated Tenro, sealing his power further away from S-Level. 'What a problematic child this is.'

Myojin got up to his feet and charged, hoping to buy Sano and Kuwabara time. Buy Kenshin and Yusuke time as well.

He was prepared to do the Banzen Gami on Tenro's head, only to revert to the Kamiya Kasshin Ryu ougi for Hadome and Hawatari when his opponent beat him to the punch and struck first with the Homura Dama.

However, as he defended against the downwards flaming strike with a cross-wrist block, Tenro grappled with him and kept him from parrying the strike. "Do you want to know how your idol, the Himura Battousai died a century ago? Like this. Guren Kaina. Homura Dama."

After the explosion from the gunpowder happened, Tenro allowed the resulting fire to flare and roast the ghost of Myojin.

"AAAHH...!" screamed the burning Yahiko.

"YAHIKO!" shouted Sanosuke.

"BRAT!" yelled Kuwabara.

Tenro himself was in the middle of the conflagration, but like with his confrontation with Hiei, he was none the worse for wear from the roaring bonfire.

"Too strong... He's too strong...!" gasped Yahiko. "Even after all this time, I'm still as weakk as I've always been."

The bright yellow flames turning blue as Yahiko's form reverted to that of a hitodama (will-o'-the-wisp).

Meanwhile, Botan shrieked, fell on her knees, and covered her eyes with her hands.

"What happened to Japan? Is this the best warriors that this new age can come up with? Pathetic," said Youkiri Tenro. "It's so sad. The United States of America turned the Empire of Japan into a whipped dog. An island full of losers."

The entirety of Okushiri started to rumble as Yahiko's neutralizing reiki ebbed away.

***

A nuke did damage in three stages.

It irradiated heat and light, it blasted everything to Kingdom Come, and it scattered radioactive materials around.

The bigger you went, the less relevant the radioactive materials become relative to the other effects as the heat irradiation had a much greater and more noticeable immediate effect. Effectively, when a nuke went off, the temperature of the resulting fireball could go up to millions of degrees, but it dissipated relatively quickly.

However, instead of having a repeat of Hiroshima and Nagasaki in 1993, Yusuke's dense aura (arguably reiatsu level at this point) allowed him to absorbed most of the impact of his Fakku Gan.

Yusuke collapsed on the ground, taking the brunt of his own spirit energy.

Before him was a behemoth of a demonized man. His exposed muscles bursting out of his skin. His bulging muscles wriggling and moving all over the place. His six huge arms giving him an insect-like vibe.

This was Toguro using a million percent of his power. He had become the Demigod Asura, a six-armed demon of war and destruction.

However, even in the face of this absolute unit of a monster, something else grabbed Urameshi's attention many miles away.

Over the horizon, he felt a suppressed Low S-Level power grow and pulse. Like a leaking and cracked dam ready to burst.

Once that dam burst, Yusuke broke all of his limits at once. Every last Spirit Cuff. Every last bit of hesitation he had from the Kugai curse placed upon him.

He caught even the Million-Percent Toguro by surprise at how fast his power level rose.

He summoned his version of the Sei Kou Ki, the golden aura serving as his barrier against Toguro's atomic punches.

His hair grew long and turned white for good measure before he proceeded to punch the Million-Percent Toguro a million times. A gold-glowing punch for every percentage.

"SEI-KOU-DAN!" Yusuke cried using the Sei-Kou-Ki version of the Rei-Kou-Dan.

He had to. That dark presence in the distance sounded all of his alarms and red flags.

Whichever Reikai Senshi was out there, they were fighting the final boss. The Chojin himself, even.

As though feeling the rise in power from a distance spurred him into action more than the golem before him that, quite frankly, took too long to get to S-Level and beyond.

***

Botan rushed towards Yahiko's side, doing her best to heal his hitodama form. But the damage was extensive on his human soul, the light in his spirit fading away. "Hold on, Yahiko-kun! I got you! Everything's going to be fine!"

However, no matter how much spirit energy she used to heal Yahiko's damaged soul, it never healed. His hitodama continued to remain in its fireball state, its light fading away fast.

Kuwabara was the first to get up shakily on his feet, the Rei-Ken in his hand flickering back and forth between its normal form and its Jigen Tou form.

"You talk too much, you bastard!" said the redhead, who attempted to create a portal to send Tenro to space, only for the youkiri to grab the teenager by his curly regent-style hair and put his face into the portal in an effort to suffocate him.

"Who is stronger? A wolf in sheep's clothing or a sheep in wolf's clothing?"

Kuwabara ignited Tenro's glove with a small Rei-Ken on his free hand, which made it explode in the youkiri's face and allowing him to escape. Gasping for air, the redhead attempted another blind swing at the would-be dictator, only for him to end up stabbed in the lung.

He coughed blood as his eyes watered. He was drowning in his blood.

"Sheep will always be sheep. Wolves will always be wolves. A hitokiri will always be a hitokiri. A youkiri will always be youkiri. It's an aberration of nature to be one thing and claim to be another."

Ignoring the throbbing pain from his right fist that somehow trumped the ectoplasmic bleeding he got from the Rei-Shuriken, Sagara did the Futae no Kiwami and aimed it right into the chest of Shishio.

Or Tenro. Or the Chojin. Whoever he was or claimed to be.

Tenro tossed aside Kuwabara's quivering body like trash then blocked Sanosuke's punch with his own punch.

Last time, Sano broke his fist on Shishio's concrete face, his own Futae no Kiwami deflecting back to the bones of his hand. This time, his Douhle Extreme was enough to match Tenro's strength.

Only to match Tenro's strength though.

As Tenro again attempted to punch and crack Sanosuke's skull open, something unexpected happened.

"...SANJO NO KIWAMI!"

Sano blew Tenro's fist away with the Triple Extreme, which opened up his chest to a direct heart punch.

The coup de grace.

"FUTAE NO KIWAMI! AHHH...!"

Sanosuke landed the Futae no Kiwami right into Shishio's heart. Or Tenro's heart.

A second passed. The youkiri cackled.

"Congratulations. You're a little bit stronger now than before."

As the fading, transparent visage of Sanosuke let out a soundless scream, his pupils constricted into tiny dots on a white expanse, Tenro finally attacked the street fighter with his flame-producing weapon, the Homura Dama splitting Sano's head apart in a spectacular spray of ectoplasm.

"S-Sano..." choked out Kuwabara, his own vision fading along with Sanosuke's soul.

All that time, even in his will-o'-the-wisp form, the soul of Yahiko kept sealing the power of Youkiri Tenro.

However, he couldn't contain the immense power of the Shishio reincarnation(?) any longer.

His soul finally succumbed, turning dark before shattering into a thousand pinpoints of light.

"Yahiko, no! No! NOOO!" cried Botan. "Dammit, come back! Oh no, what's going on? Why is everything going wrong?!"

Okushiri rumbled as the unleashed power of Tenro began to expand into a tall pillar of darkness and miasma. His jaki shot up into the sky, which gathered nimbus clouds all around them.

The localized quakes grew stronger and stronger. It felt like the world was about to split apart. This was the power of an Upper Class-S being somehow ending up in the Human World.

He felt like power made flesh. A walking disaster area. A humanoid cyclone.

Tenro smirked as he surveyed the horizon. He felt their presence. They were coming. He felt their desperate presence travel towards him.

One was on land, on foot, going faster than a cheetah. The other in the air, presumably ferried by one of Reikai's shinigami.

First, there was the one half-demon, half-human mazoku descendant of Raizen, Makai's God of War, who was able to harness his demonic power and lineage. Raizen's true son. The Last Son of the Mazoku.

Yusuke Urameshi.

Second, there was the man who "defeated" Makoto Shishio to a suicidal draw.  The Hitokiri Battousai who died and then became the Youkiri Battousai, the Guardian of the Demon Sword.

Kenshin Himura.

"Come forth. Show me the best and most powerful champions that this era has to offer. I'll defeat them all!" declared Tenro the Demon-Slayer to his upcoming opponents.

He could feel their strong presences, spirit energy, sword energy, and aura even from miles away.

However, before Tenro knew it, his chest tightened. His heart stopped beating.

His negative energy wasn't able to heal the damage in time. He stood there, frozen. His time had stopped care of Sanosuke's efforts.

It was a combination of the Futae no Kiwami damaging his heart with the shards of Yahiko's neutralizing reiki. It kept him from manifesting the full breadth of his power that managed to take down even Hajime Saito.

The Kenshingumi's curse, if you would.

"Before challenging the champions of this era, watch out behind you first. The past has a way of catching up with you, Shishio Makoto!"

Speaking of Saito, it was then and there that the headless corpse of Saito began moving on its own, with his one arm cradling his decapitated head.

As though he were the Headless Horseman. Or a Dullahan of Irish folklore.

That bastard. He was playing possum all this time!

Tenro willed himself to move, but couldn't. He felt his left arm go numb. The shards of Yahiko's sakabatou might've reached all the way to his coronary arteries.

There was no telling how much cardiovascular damage Sanosuke's punch had done to his heart.

Dammit.

He began to sweat hard while clutching his chest. "Damn you, Saito Hajime."

"I've never seen you so sweaty before," the head of Saito said before charging with his Gatotsu Ishiki from behind Tenro. "Then again, your sweat glands did get all burned up in a past life."

Instead of aiming at Tenro's head like with his encounter with Shishio, Saito instead aimed his sword right at Tenro's stopped heart while he was in the middle of a heart attack.

Appropriately enough, instead of being defeated by someone stronger than him, it was the desperate alliance of those weaker than Tenro that ultimately dragged him towards his ultimate defeat.

The ultimate irony.

"Go back to Hell, Shishio...!"

"No, I will make this world Hell and feel right at home!"

No. This was the same method Hajime used to "kill" Usui (temporarily). He took advantage of other people's hard work then opportunistically struck.

There was no way Youkiri Tenro would go down like a punk. Like Usui, of all people. An outsmarted weakling.

Tenro willed himself to move to block the strike.

His Homura Dama melted right through Saito's sword. Apparently, the Shinsengumi Captain was already using the last of his soul's strength to even make the strike, leading to a vulnerable blade with barely any spirit energy to protect it.

Nevertheless, the rest of the hot blade plunged right into one of Tenro's lungs, spraying his blood all over.

Saito smirked and closed his eyes.  Instead of a soul, Shishio really was reincarnated into an extra powerful human being. But a human being nonetheless. A mortal that could be killed.

Tenro awaited the Gatotsu Zeroshiki that never came.

However, Saito already spent most of his energy fighting a full-powered X-Level Tenro earlier, with him sacrificing his very life force to just injure him now.

"I win again, Saito Hajime," hissed Tenro, coughing blood. "I survived your attack while you're already as good as dead. I can easily heal through this and finish off the rest of the Reikai Senshi."

"That's my parting gift," said Saito, his own spirit fading. "You won't be able to reach X-Level in time now."

Before Tenro could wonder any further what Saito meant by his words, a gigaton punch shattered his face from out of the blue.

"Wha...?! GUAAAAH!!!"

Again, the wolf outfoxed him at every turn.

The youkiri realized that he'd just been punched by Raizen's "Son". The Mazoku Descendant. The hanyou (half-demon) that scared Enma Daio himself.

His brain sloshed inside his broken skull, leading to a concussion.

Any other impact from a weaker opponent wouldn't have even registered. But a punch from an S-Level mazoku? That was a punch that could tear apart entire continents.

He also spotted from behind the long-haired, tattooed, and angry Mazoku Yusuke a warp portal that Kazuma Kuwabara probably made to shorten his best friend's travel time.

This was bad.

His compromised heart and lungs hadn't recovered yet. Even though his energy levels were rising, his mortal damage kept him from manifesting his full power. He wasn't healing fast enough.

But this was also exciting.

Tenro missed out on slaying one of the greatest, oldest, and most powerful demons of the Demon World, Raizen. Fighting his distant half-breed offspring was the next best thing to it.

With Yusuke's white hair and boundless energy, he looked to be at the cusp of X-Level himself.

"Far more important than your power level, you've upended the natural order of things in both the Spirit World and the Demon World."

Yusuke picked up the pace, his nuclear-powered punches reaching speeds so impossibly, superhumanly fast that they came with their own eardrum-obliterating sonic booms.

However, the tough-as-nails Tenro absorbed every punch with his hard body, so his mountain-obliterating punches "merely" made the pier shake and quake like a scared child.

"When Raizen died, you took over and found a way to keep the warring factions of Mukuro and Yomi from leading Makai into another millennia-long war for power."

Tenro gurgled but laughed with what sounded like a death rattle. Knocking at death's store with the sea of punches he had to wade through while punching and slashing at the elusive demon spawn in turn.

"You even helped expose the corruption within Reikai and had Koenma Daio depose his father, Enma Daio. Then you saved the Human World again from a Spirit World terrorist group. Imagine that."

The constant battery of kicks, punches, knees, elbosws, and headbutts that barely gave Tenro any breathing room took their toll, making him cough and spew blood from many of his body's orifices, like his ears, eyes, nose, and mouth.

"The Chojin views you as a threat not because of your power level but instead of how you affect everyone and everything around you. You're a spanner in the works. Someone who can defy fate itself."

The threat of death made Tenro feel alive. His flight or fight instincts were on high alert.

After the thousands of demon hunts he'd participated in for the sake of turning his reincarnated yakuza boss self into someone worthy of housing Makoto Shishio's soul, this was the first time he actually, remotely felt threatened.

It was as he had imagined facing Yomi, Mukuro, or Raizen would've been like when they were still the Three Kings of Makai at the peak of their power.

"We're cut from the same cloth, Urameshi Yusuke." Tenro sneered, wiping the blood from his nose. "From one lion to another, I will fight fate itself to write my own destiny. Just like you have."

"What are you blathering about?" said Yusuke, who kept up his endless barrage of Sei Kou Ki punches and kicks in order to pummel Tenro to submission.

Although he was winning the exchange, Toushin Yusuke's fists were aching and bleeding.

They might've even been broken by the dense thickness of Tenro's own reiatsu of negative energy serving as a barrier from inside and outside him that kept his human body intact.

Regardless, the human-demon spawn had to finish Tenro off immediately.

Even though Urameshi was able to best Toguro by going all out, he could still feel his old enemy's presence. If he could heal, then he could possibly go beyond a million percent of his power. Perhaps a billion or a trillion even.

"Let's end this, Tenro. Or Shishio. Or Chojin. Whoever you are.  I'll finish you and your Shin Juppon Gatana off! SEI-KOU-GAN!"

A black-and-blue Tenro grinned as he felt a meteor-sized blast of purest Sei Kou Ki grow bigger and bigger from Yusuke's pointer finger. A miniature sun that glowed gold instead of bright blue.

This was the correct move. In order to finally penetrate through Tenro's reiatsu, Yusuke had to use his ultimate, ultimate move. A Rei-Gan powered by Sei-Kou-Ki shot by his white-haired demonic form.

However, the Chojin foresaw all this. This was why he gave (back) Tenro his original Mugen Jin.

When Yahiko still had his neutralizing reiki activated, the Mugen Jin could only be used the way it originally was made for, which was to use body fat and human oils to constantly ignite flames unto it.

However, a hundred years later, the sword itself became a cursed sword with supernatural powers like the Youtou Shinnoken. It gained an extra property.

Without Yahiko's powers sealing its supernatural abilities away, it could absorb, steal, and store energy.

Thus, Tenro's Mugen Jin absorbed every last bit of the Sei-Kou-Gan from Mazoku Yusuke, only for him to do the third secret sword on him powered by  Urameshi's own Sacred Light Spirit Energy against him.

"Secret Sword Three: KAGUZUCHI! (FIRE-BEARING SPIRIT GOD!)"

A fire tornado that mixed Tenro's demonic negative energy reiatsu with Yusuke's angelic sacred energy tossed the teenage warhead around in a maelstrom of discontent (since jaki was basically just energy let off from humanity's hatred and grudges).

If the mixture of volatile energy didn't kill the demonized Urameshi, then the centrifugal force of an F5 hurricane that would normally turn any normal human being into liquefied butter would.

"Hiten Mitsurugi Ryu Ougi: AMAKAKERU RYU NO HIRAMEKI! (HEAVENS GLIDING DRAGON FLASH!)"

The void created by the ultimate attack of the Hiten Mitsurugi Ryu destroyed the red, black, and gold wind funnel that had threatened to rage against Okushiri like a seasonal typhoon.

As a battered Yusuke fell to the sky, an erstwhile Kenshin jumped and caught him in midair before he crash into one of the many cargo containers, if not outright fall into the hard concrete below.

They landed safely on ground zero of Yusuke's fight with Tenro, which was filled with craters and debris. From a distance, they could hear the blaring siren of an ambulance.

"I came here as fast as I could with Ayame-dono's help," said Kenshin.

"K-Kenshin. S-Sorry. I-I almost had him, but he still had a trick up his sleeve," rasped Yusuke, who had transformed back to his human form, with most of his long hair burned away by Tenro's Kaguzuchi.

"Don't worry, Yusuke. I will finish off what you've started. What everyone had started, that I will," said Himura.

Tenro harrumphed, clutching his side. His chest still ached, his heart beating so fast it felt like it could explode. His brain throbbed and pounded inside his skull.

However, his adrenalin and his thrill for the fight soared, making him ignore every bit of pain he felt. He was about to pass the point of no return, after all.

"The fates conspired against me and denied me my destiny to rule. I write my own destiny  now," said the youkiri to his fellow demon-slayer. Fellow manslayer, even.

"Time has already chosen. You were meant to lose," rebutted Kenshin. In the corner of his eye, he saw Botan stare at him with glistening eyes.

He heard the bad news from her. She reported that the souls of Sanosuke, Yahiko, and Saito were no more. Also, Kuwabara and Yusuke were in critical condition.

They all fell against the hands of the man... the monster... before him. The wannabe dictator that he should've defeated a hundred years ago.

"I also look forward to seeing you again after all this time, Battousai. Come and die in my hands once more. The only law I follow is Survival of the Fittest. Only the strongest survive!"

"Survival of the Fittest, eh?" asked Kenshin. "Do you know what is the first sign of civilization?"

"...What?" asked Tenro in turn. "What are you talking about, Battousai?"

"I believe that the first sign of civilization is a femur that's been broken and then healed," said Himura. "In nature, a broken leg meant death. Kill or killed, right? Humans became the dominant species against stronger animals because of our cooperation and compassion. Helping someone else through difficulty is where civilization starts. We are at our best when we serve others. Be civilized."

"No. Nonsense," said Tenro. "Humanity stands on the shoulders of giants. Without the strong, the weak shall die unless they too can become strong. Otherwise, humanity will decline. Don't let the weak punish the strong for being strong while celebrating their own mediocrity. Civilization or progress came about because of the strong. The best. The intellectuals. The Superman. The Overman. The Ubermensch. The Chojin."

"Chojin..." said Himura. While it could be translated as "Overfiend", the name "Chojin" could also be translated as "Superman" or "Overman". "Fate and time have already decided that you will not emerge victorious."

Tenro cackled. "Fate and time have chosen poorly, hence the pathetic state of Japan. The state of the world that's being led by sheep in wolves' clothing. Let me correct that century-old mistake. Even now, the weak are depending on your strength to protect them. Let the Ubermensch show the world what it's truly like to be strong! I will show them how to win!"

Kenshin fell into his battoujutsu stance. He had to attack now, while Tenro was injured and recuperating. As soon as he healed and achieved X-Level, it was all over for them.

"AMAKAKERU RYU NO HIRAMEKI!"

"KAGUZUCHI!"

Kenshin and Tenro... or rather, Kenshin and Shishio... finally clashed swords, the Youtou Shinnoken glowing bright-blue against the bright-red Mugen Jin. They picked up where they left off.

In one timeline, Kenshin found the strength and will to live to block Shishio's strike before he spontaneously combusted and died from overheating. Soon after, Shishio became the new King of Hell.

In another timeline, Shishio finished Battousai off then murdered Saito, Shinomori, Sagara, and the rest of the Oniwabanshu and Shinsengumi before forming a New Juppon Gatana and leading a coup d'etat against the Meiji Government. A second Bakumatsu. Afterwards, when he died, he came back to the Human World with his New Juppon Gatana.

In the timeline they were in, Kenshin and Shishio fought to a draw, with Kenshin dying along with Shishio in a blaze of glory. A hundred years after their battle, and Shishio ended up forming a New Juppon Gatana in order to lead a coup d'etat against the Spirit World.

In nearly all timelines, Shishio woke up from beyond the grave and ended up with an army of the undead, leading the charge towards world domination. Like a phoenix reborn from the ashes. Again and again.

Even after his death, he was inevitable.

Would Kenshin falter like a hundred years ago or would he rise up and correct his century-old mistake?

On one hand, Yusuke's leftover sacred energy powered up the Kaguzuchi overwhelmed the initial strike of the Hirameki. On the other hand, the resulting void still formed, which multiplied the power of Kenshin's second strike many times over.

Tenro learned from his mistake, understanding that there was a void formed after blocking the first strike of the Amakakeru Ryu no Hirameki. He sunk his stance low and pierced his Mugen Jin in the eye of the maelstrom so that his technique could be magnified in power instead of Kenshin's.

Kenshin hesitated, his soul remembering how Shishio snatched a draw from the jaws of defeat. He willed himself to slash upward regardless as an image of Kaoru filled his mind. Followed by all his friends and comrades.

He wished the same image had filled his mind a hundred years ago too. Then he wouldn't have died. Then he wouldn't have turned into the Guardian of the Demon Sword.

Then, in the Second World War, he wouldn't have...!

A shining star of a whirling, converging afterimages happened afterwards, followed by a huge explosion far into the distance. Right into the Sea of Japan.

Reality seemed to split from the lightspeed slash Kenshin did that clashed hard against Tenro's... no, Shishio's... red-hot cursed sword Mugen Jin. On Kenshin's left was one timeline and on his right was another.

A 7.8 earthquake then rocked the west coast of Hokkaido.  

On Monday, July 12, 1993, at 10:17 PM, a tsunami had formed off of the coast of Okushiri, leading to the loss of many lives.

***

To Be Continued...

Oh god, finally it's done. This took years to finish due to real-life things cropping up. Regardless, the arc that's been decades in the making is at last over.

Next up, the Spirit World deals with the aftermath of the failed Okushiri mission. Also, the first sign of civilization speech was taken from a quote from Anthropologist Margaret Mead.

Ciao, Abdiel
