pt. 2 | NARUMI GEN WITH A MITSURI! LIKE READER🌸

🌸Previously we focused a lot on Mitsuri! Reader’s background, now, I want to show her relationship to Gen in particular after becoming a platoon leader and drop some interactions with Kikoru!

part 1 | Masterlist

🌸Tags: narumi pining stage(?). oblivious Narumi, mutual pining, mutual admiration, friends to lovers but not yet question mark, loser narumi, OBAMITSU NARUMI AND READER!!!

Well into your time in the First Division, you’ve established a rather interesting sense of partnership with Narumi Gen.

At first, the two of you were still quite stiff, what with how it seemed like you and Narumi were just too different in terms of personality.

One was a lousy trash man–brash, childish and stuck to his handheld when he wasn’t on the field, and while the other was a happy go lucky, passionate girl who grew to be well loved for her demeanor, you were quite shy when it came to approaching him. After all, he IS your captain and the man on top of the Defense Force. You had a great deal of respect for him even before you joined arms. In fact, striving to be worthy to stand with him–to be stronger, was the collective ambition of every officer there.

After finally earning his acknowledgement, you ended up spending more and more time with him. Since you caught his eye with your strength. then you’ll have to keep honing it if you were to prove your existence. So you trained and trained, kept your limbs stretched, made sure your flexibility and agility always stayed fresh in your blood. Turn it into second nature. 

And whenever the captain threw his hand in and actually showed up for a couple of rounds to spar you, you gave it your all. It became clear that he in particular took part in stoking your flames with his principle. To show results.

With that in mind, you’ve been building blocks since the very beginning, he notes one day, rummaging through your files and every assessment result.

Your shooting range assessments during your time as a rookie. Physical check ups. Combat training. Laps. They were above average–it’s what landed you in the First Division in the first place.

But what made you shine was your insane physical prowess, and how superhuman you were with transferring your power to the weapon you held.

Your terrain practice and obstacle shooting course held the highest rookie records. Your field reports never lied, there was even drone footage. Then there was the daikaiju incident, where you wielded an entire machine gun and amassed such a formidable blast upon first use, the numbers were too overwhelming for a rookie.

He remembers another report he got after your health assessment. They had studied the composition of your muscles, your combat levels, and more. Gotten real up and personal with you, so much so that you noted the experience while looking away. 

He’ll never forget Isao’s words after Hasegawa recounted their discoveries in his office. Your extreme constitution, your rapidly increasing combat power, your leap in abilities as soon as you donned on your suit. Your power.

“Another prodigy right after Ashiro Mina.” Narumi paused as Isao turned to face the both them. “The next piece of the puzzle for the Defense Force.”

If Mina was the missing link to fight daikaiju–humanity’s biggest threat at the time, then you were second just to her to complete the frontlines. Another sleeping tiger.

Isao himself gave him and Hasegawa an order. One that drove home the responsibility he had as your captain now. “Hone her strength. A girl with her potential belongs in our main defenses.”

He made you sound all cool and all, but as soon as Narumi made his way to the training hall, he was flabbergasted as you held a comically long photostrip filled with the pictures of the cats you had back at home, gushing over them with several of your platoon members.

“I love Nekotarou, General Whiskers the 2nd, and Meowy Antoinette soooo much!” Were those the names of your cats? He wonders. “I’m going to spend my life savings on building a shrine in their image near Yokohama Station.“ Impossible.

Hearing that gave Narumi whiplash. Right, the daikaiju prodigy that even Mr. Isao acknowledged…

So there you were one day, nervously looking down at a serious private meeting with your Captain and Vice Captain. “You know, Mr. Isao went over some of your assessments some time ago.” Your heart immediately dropped, your shocked expression instantly showing on your face.

“DIRECTOR GENERAL SHINOMIYA?!?!?!?!” Narumi watched as you, noting how you were akin to watching a hamster get scared by loud noise.

You quickly regain your composure (though you still looked comedically nervous in Narumi’s peering eyes) as he read out your achievements. You’ve already proved yourself well, with a high performance level that was brimming with potential.

But most notably, it was your high physical prowess and how superhuman you were with transferring your power to the weapon you held. That was what made you a force to be reckoned with,

“So, with that in mind–” Hasegawa stood up, followed by Narumi. “As a newly appointed platoon leader with one of the strongest, most unique combat power readings we’ve had in the force, we will start work on your special weapon.”

“...” You stare at the two of them. Narumi stares back. Hasegawa paces his sight between the two of you. Then, the words processed in your head, and you let out the biggest beamful smile they’ve set their eyes on. “THANK–THANK YOU SO MUCH!” you stifled a few tears, following them like a duckling to meet with Izumo Tech.

And after a long testing period, you were bestowed with what the people at the weaponries department could only describe as a weapon as unique as its user. Your whip-sword.

With how unique your weapon was, it was imperative for you to train twice as hard–learning the ropes and making sure your new fighting style was worth all the effort. Your pride as an officer–a bearer of a special weapon relied on this. That was when Narumi rolled in, and when he wanted to test your strength himself, you eagerly accepted. Unexpectedly, it turned into a new tradition between the two of you.

Around this time was the turning point of how you slowly broke out of just simple subordination to him, and towards a strange yet delightful symbiotic relationship, one where you didn’t just acknowledge each other’s strengths, but learned more about the person behind them. He started talking to you more once you asked him excitedly about what games he plays, and he started to eat the meals you brought.

Truth to be told, your journey only became more arduous then. You were strong, sure, but you still couldn’t hold a candle to Narumi. And it only spurred you on further.

A particularly remarkable moment between the two of you was the first time you really voiced your compliments to him outloud (to Hasegawa’s dismay…)

It was when he beat you in hand to hand combat one day, and perhaps something felt different with how you were pushing your blood circulation and heart beat to the limit, but it was super clear that he really went all out that day. And he was admirable. “You’re amazing, Captain!” 

“Of course,” he was to reply to you instinctively, but the sheer look of admiration you had sprawled on your face despite getting floored took him by surprise. You were always holding back a little around him–though he knew from word of mouth that you really were a very excitable person–so to see this other side of you was still pretty new for him. He just soaks in your words as you continue.

“Your form is amazing, how long did it take you to perfect it?” “I need to up my precision too. Yours is so remarkable.” “Please let me spar with you more!”

Perhaps you let your mouth run a little too loose by then. “I hope to one day earn my place next to you, Narumi–” You stop. Narumi stops. Then, your hands fly to your mouth as you let out a choked sound of what seemed to be your life regrets. “--I’m sorry!!!” Your forehead had already hit the floor multiple times before he registered your apology, seeing you fret over thinking that you overstepped a line.

But things are okay. You’re good friends now. He’s confident with that. He’s seen all 2760 of the pictures in your “my cats❤️❤️” album on your phone. He has all your favorite foods memorized. He knows the best ways to bait you.

He also had a huge ego boost when you showed up one day with the ends of your hair dyed a new color, following the long tradition of the 1st Division platoon leaders.

Has been scolded once or twice by Hasegawa for making you stay up late helping him farm dungeons on his BS5. When Narumi rebutted that he was your captain and that this was “an important mission”, Hasegawa promptly shot him down by stating that it was abuse of power.

He was actually the first person you showcased your new fighting style with your whip-sword to. Still couldn’t believe that you actually named it after your cats.

When the time came for you to use your new weapon on the field for the first time, you felt a bit more pressured than you should. Despite the fruitful results from in house training, the field is a very different environment, and you couldn’t afford to mess up. This test drive meant a lot–developing your weapon probably took a fortune–and you didn’t want to disappoint Narumi. He spent so much time with you. For you.

You move towards the approaching Yoju with total concentration, launching yourself in the air. “MTS-1437 field test commenced. Initiate subjugation,” Kurusu announced through the comms whilst giving you clearance, the operations room watching expectantly.  

To say it was a success was an understatement. Not when the entire operation room seemed to look at your floating figure in awe, your sword gracefully twirling around your body. You looked as light as the wind, so graceful and elegant as you zeroed in on the yoju, before unleashing an onslaught of the techniques you spent so much practice on. Seeing you with your sword dance didn’t just fit your entire being amazingly – It felt so right.

Inside of him, Narumi felt a sense of achievement, watching you from the operations room as well. 

“...Did she just say Catlove Shower?” He tensed, coughing a bit. 

His memories bring him back to the specialized training room the both of you frequented, when you had eagerly just showed him your techniques. He remembers how gleefully you smiled, how your eyes turned into half moons from how elated you were after he gave you his approval. It was just a “good job” he thought, but it must have meant the world for you. Your place in the force must have meant the world for you. Something in his heart started to tug.

Before he realized it himself, a snide remark came out of his throat. “She was really happy with the names she thought up–so shut it.” Everyone near his vicinity tensed, looking at him in shock. No one expected him to comment that, not even Hasegawa.

As mentioned in the previous headcanons, you and Narumi have grown accustomed to each other’s fighting style. As you also worked with the combo of gunmanship to melee–though not exactly similar, you had turned to him for a lot of pointers. Not only that, but the joint weapon training you underwent with him contributed a lot to both of your understandings of how the other fought. So, it was no surprise that your battle sense became more reminiscent of his.

Narumi only let you join his side as soon as he knew he didn’t have to worry about you. As much as he valued you as a person and the friendship you had, he knew that the laws of the battlefield were strict. He couldn’t trust himself if he couldn’t trust you to handle your own. Especially when the 1st Division handled the toughest of kaijus.

His tough love and constant, merciless training made you stronger. And truthfully, seeing you advancing so rapidly in his eyes scared him a bit (was this what Isao felt?). So he was immensely tough on you. You had to be strong.

But when it came to Narumi and your beloved 1st Division officers, you quickly reminded them of the you behind your strength. The (Y/N) that smiled and earned herself the title of the Pillar of Love, the pink creature that made up the most unlikely duo on planet Earth with Narumi Gen.

It’s the mutual understanding and respect you have with each other that brought your bond both in and out of the battlefield this far.

So when Kikoru rolled in, she couldn’t help but admire you. At the time of her transfer, you were a name she’s heard whispers about. The 1st Division’s pillar of love. An expert heavy hitter who excels in mid ranged combat. Exactly someone she could confide in in improving her techniques with the axe.

And Gen used this to his advantage.

“Oi, Narumi.” He winces in pain as you whack the top of his head in place of Hasegawa, letting out a string of complaints. “As much as I love Kikoru-chan, I don’t think General Shinomiya would appreciate it if you threw all the training to me.”

“I told you, it’s our dual responsibility,” he says in between button mashing his console, “I gave you the order to help teach her the ropes. You have a similar combat style with hers.”

“I trained with you, and you’re training with her. Which means I’m training with–” cutting off his speech, you brazenly pick up his lawn chair, balancing the captain as you carried the seat to the training grounds. You made it look so easy.

“My apologies, captain!” Kikoru watches in stunned silence as you haul him over to where the two of you were previously sparring, dropping him on the ground gently whilst listening to his childish rebuttals.

The blonde only watched as Narumi rose from his seat and yelled out more curses in an annoyed frenzy, now chasing you in circles as you held his handheld controller. You were expertly dodging him too, maneuvering the strikes he made with his hands and feet. Yet it despite the showcase of skill, it all felt too goofy to be real.

Was that… really the strongest kaiju combatant in Japan and the famed love pillar?

“GIVE THAT BACK!” Narumi yells, reenacting a forward strike so cleanly, it had Isao written all over it. He narrowly misses your body mid jump.

“MY APOLOGIES!” Your apologetic tone could not be more contrasting than your actions as your legs landed on his head, pummeling Narumi to the ground for your landing.

At this point, even Kafka was watching with his jaw on the floor, Kikoru beside him watching intently. “Even in a light quarrel, those two are masters in their field! But still…” She zeroes in on the tug of war for Narumi’s console between the two of you.

…Could she really trust the two of you during her time here?

Kaiju No. 8 Relax Ch 2.1: Kaiju No. 8 and the Arcade

More manga pages for KN8 Relax! I'll be reblogging the last few pages since there's more than 10 pictures.

[talesofsonicasura]

Free prompt for UnderDogs/Hoshikaf shippers!

Kafka and Soshiro being married before canon happens. Like they tied the knot four years ago with the former being a pseudo House Husband of sorts. Kafka still works at the Sweepers but has extra free time since he is a highly trusted worker amongst the organization.

The night our himbo gets his powers? It was supposed to be their 5 year anniversary but a certain Spider Honju had to ruin it. Also Soshiro visiting Kafka in the hospital and watch Tiny(the larval/mosquito kaiju) go down his husband's throat.

He definitely tried to use the Heimlich Maneuver on the man but our himbo ends up knocking the wind out of the vice captain via a elbow to the gut. A kaiju metamorphosis would boost a panicking person's strength after all. (Kafka definitely will feel bad for the bruise he left on his husband's stomach.)

You can bet your ass Soshiro would be extra protective of his himbo lover thanks to this incident. The vice captain already had a mini existential crisis about mercy killing Kafka if he became feral after turning into a Kaiju. It was a massive relief the man retained his identity although with some added primal behavior.

No way to make your love life more chaotic than your husband becoming a kaiju! (I would've made it more insane if I used Skyscraper Softie!Kafka for my personal take.)

[i-literally-cant-with-this]

This is an oddly specific request but could I ask for headcanons with Kafka and a reader who’s on the curvier side? Like I’ve got DDs, I have wider hips, and like Kafka I have abs but only if I suck in my stomach. So I guess I feel very seen and validated by his body type??

Sfw/nsfw is fine, and feel free to delete this if it’s too vague. I hope you have an awesome day! ☺️

MDNI under the cut, please and thank you!

A/N ::: I woke up at 4:30 this morning and am falling asleep as I write this lol. Proofed as well as I could for the remaining brain power I have.

Anon! I LOVE this so much. And oddly specific requests are fine with me. It just means I have more to work with! I hope you like this and that it meets all of your needs =).

Always had a soft spot for women with more to love. And you've only made these feelings of his grow in intensity.

Can't believe YOU are interested in him. Sure, he knows he's strong and relatively good looking (my god, he deserves the world) but only recently has he started to feel really comfy in his own skin.

Respects the hell out of you for being so confident in your body.

Never tires of seeing you walk around in your bra when you get ready in the morning.

Has trouble focusing on his breakfast when your tits are looking so much more delicious than what he's trying to eat.

Has given up on finishing his food more than once to take a few well-placed bites of you.

Can't get enough of your ass, especially when you're bent over something in the kitchen. Or the bedroom. Or the bathroom. Anywhere, really.

Comes up behind you and starts to rub your hips, squeezing and pulling at you, whining because he doesn't want to wait until later to have you all to himself again.

You've let him indulge in his fondness for the softness of your body more than once.

You're nearly convinced that he likes what he's doing to you more than you do.

The way he reacts when he's eating your pussy, moaning and pulling your body closer against his face, his big arms wrapped up under your thighs and his hands almost turning white they're gripping the fat of your legs so hard.

It's like he's possessed, unable to control himself.

And when he fucks you, his abs bulge and flex as he slams into you, his cock hitting all of those spots deep inside of you, driving you mad.

Does his best to let you cum first.

When he finishes, sometimes he'll pull out and cum all over your tits, stomach, ass. Any part of you that he's fixated on at that moment in time.

Has had trouble deciding and almost ruined his own orgasm - luckily, there are only beautiful parts to you, and he was able to finish anywhere.

He's never had a preference for where he puts it before, but with you he just seems to really like to cover you in his cum.

Provides world-class aftercare.

He offers you anything he can think of that you might want or need.

Warm washcloth to clean up a little? Sit tight, kitten, he'll be right back.

Hungry? Where do you want to eat? He's famished, anything you want sounds great to him.

Thirsty? He's already walking his chubby, jiggly naked butt down the hall to the kitchen for a glass of ice water for you.

Tired? Great, so is he. The two of you have curled up more than once to take some quiet time for just you.

He's got you covered for anything.

So grateful to have someone so loving, patient, and caring in his life.

Fights (playfully) with you about who is luckier: You or him. But he never backs down that he's the clear winner here.

GET HIS ASS, KAFKA

[sonicasura]

Hilariously fucked up idea but what if Kafka's kaiju had a starfish moment?

Like when Hoshina cuts off his arm during their fight in episode 8, the limb just turns into a mini baby version of the himbo's Kaiju form while they are unaware. Nobody notices until two possible scenarios occur. (Both will have at least two months for shenanigans before No.10 shows up.)

1. Hoshina finds the whelp as he hears it rummaging through the garbage. He was gonna bring back the arm he'd cut off from No. 8 only to notice it strangely gone. Imagine his face when he goes to investigate only to see a little chibi skull look back at him with puppy eyes.

The 'Oh fuck' look as he realizes what he inadvertently created especially when the whelp starts happily chirping at him. Hoshina brings the baby back since those puppy dog eyes pretty much sniped any willpower to snuff it out and it might help the Defense Force understand No. 8 better. Yes, Mina is definitely picking on him once she sees the whelp. (Gonna call them Skully for now.)

Poor Kafka gonna have a major inner freakout for two reasons. Skully pretty much is like a koala and throws a fit if away from Hoshina for too long so the entire 3rd Division sees them. The other reason is the whelp immediately knows who their momma is thus has a tendency to sneak away to see Kafka.

2. Our himbo suddenly senses something strange after he escapes Hoshina. Following his instincts, Kafka soon finds the newly born Skully munch on one of the dead kaiju corpses. The baby immediately begins to chirp happily at the stunned himbo.

Kafka ends up hiding Skully in a bag he takes off the street and goes to Kikoru for help. She absolutely has a freakout cause the man is really pushing his luck with a mitosis kaiju baby in a battlezone! (Kafka does try to defend himself since he didn't know how freaky these powers were gonna be.)

It's the three stooges with a kaiju baby time as our himbo needs all the help he can get. Even moreso when Skully likes to wander off in order to find their 'papa' Hoshina. The baby already gets fussy if Kafka is absent for too long and his kaiju instincts hate leaving them alone for similar reasons.

With either scenario, someone is gonna face the struggles of parenthood. Lol

Merfolk Headcanons

My take on merfolk from their biology to societies. Expect a good chunk of my works to incorporate these to an extent. Any fandom related ones like for KN8 will be labeled as such. Y'all are free to utilize this if you want. The only thing I ask is to maybe link the page so others can see it for themselves! Let's get started.

Merfolk consists of multiple species than just mermaids and mermen. Sirens, Selkies, Nereids are some examples amongst this diverse species. I can't forget the various subspecies and hybrids that slowly emerge from this tree of evolution.

Merfolk are related to humans through a distant ancestor. These individuals began to steadily adapt traits perfect for aquatic environments. An evolution that soon made them amphibious in nature before truly becoming the mers known today.

Merfolk slowly began to disappear from the eyes of their land locked relatives. Quite a few believe it was due to rising conflict between both races. Whatever the reason, the aquatic species soon faded into legend as they lived in their own underwater communities.

Of course merfolk also had their major conflicts just like humans. Even civil wars before a treaty was put in place to avoid self made extinction. This treaty led to a massive renaissance amongst the species, particularly in the realm of medicine.

Antidotes, antibiotics, vaccines, and any other cure to the ocean's maladies. Multiple species of merfolk were venomous in nature so these cures dropped illness or death from poisoning drastically. Especially since young mers have difficulty controlling their venomous bites and stings.

The latest development in merfolk medicine was actually prosthetics. Whether materials from items humans tossed to the sea or what their natural environment has to offer varied. Even merfolk can suffer grievous injuries so these prosthetics could make living easier.

(Kaiju No. 8) When kaiju began to infest the sea, multiple merfolk inventions were halted and possibly lost. The schematics to prosthetics were one such thing. Stone slabs depicting these life saving aids often found themselves in places like auction houses.

Another type of merfolk creation was bath soap, especially bubble bath. These aquatic individuals do love a good bath and multiple bathing places are hidden amongst the sea. Even hot springs which became popular with the elderly or ailing mers.

Merfolk bath products are 100% environment friendly compared to most of their human counterparts. Some even have more potency in certain areas. Merfolk bubble bath create huge bubbles that are able to be entered and played inside. Although caution is advised as they are meant to be played around water since contact with land or a sharp object would pop them.

Like humans, merfolk have planned on how to handle disasters. Especially if it makes the upper part of the ocean too dangerous for them to live. An emergency 'bunker' deep within the sea referred to as the Depths.

Should an event occur that requires this shelter, nearly all merfolk will retreat to the Depths. How long they stay down there varies but there's enough materials and supplies to keep them alive but also content. Not all merfolk retreat to the Depths as a good chunk of pods decide to tough it out.

Whether its stupidity or hubris which drives these rare few are unknown. Though the chances of their situation becoming complicated also arise. Some mers are born with a dormant mutagenic gene.

It slumbers amongst the unaware population unless certain perimeters are met. The main reason being if the environment in question has deemed itself too hostile for the host to survive. It's at the moment where it'll awaken and begin to mutate the mer.

The mutations depend on what is potentially threatening the host's life. Adaptations can be minor like hardening of scales, the ability to camouflage, being able to withstand inhospitable environments, etc. However there are occurrences where the mer becomes monstrous.

(KN8) Due to the threat being kaiju, the mutation merfolk go through is called Pseudo Kaijufication. The hosts in question begin taking on kaiju traits from size, advanced regeneration and even develop unique abilities. All of them share a stinger-like tail which is actually their old body's tail fin rendered useless.

These mutations often come at a cost as they become less merman/mermaid to fit their new kaiju genetics. Kafka lost his ability to take on human form and his enchanting song. In exchange he got a powerful ability in the form of Self Biological Manipulation alongside electrokinesis.*

All merfolk possess the power to take on human form. This requires the individual to dry themselves on land. Inside their body is a gene that is responsible for the transformation via their skin.

Whenever dry, a mer's body will expel the excess moisture creating a thick screen of dry steam as a result. All their animal traits recede into human ones without the needed water sustaining it. Some spontaneous fog banks are the result of Leviathan class merfolk taking human form.

If their outer skin touches water then they revert back. The gene orders their body to draw in water particles within the air at a rapid rate. Moister the area, the faster the reversion is. Some crafty merfolk created tonics that can temporarily nullify this gene for a few hours.

Quite a few members of the species secretly live amongst humans. No one knows how many people have a merfolk lineage but some guess around 22%. A human/mer couple can bear human and mer offspring.

The chances for either varies between individuals. Whether the 'mother' is human or mer doesn't matter at all. A few scholars believe it's because both races are distant relatives thus they share similar genetics.

The animal half of a merfolk usually affects their mannerisms and biology on certain levels. For example, some subspecies are born intersex/hermaphrodite if they're part sea slug or cuttlefish. Terms for offspring, how they are born, and terminology also varies.

Merfolk come in different size classes with the smallest being Mini while the largest is Leviathan. Every subspecies has a chance to be born in any size class despite the nature of their animal halves. Leviathan: 31-50 ft except for some rare cases being even bigger, Large: 19-30 ft, Medium: 10-18 ft, Small: 2-9 ft, Mini: Less than 2 ft.

All merfolk can have offspring with each other no matter the size class. This unique biology is the main reason why they usually travel in pods of varying sizes. Someone will be able to tend to offspring if the parents are indisposed for some reason.

A few merfolk do live solitary lives under different reasons. Sometimes it is their choice since pod life ain't for everyone. Most of the time it is by banishment via majority vote or the leader. The same condition is given to the mer's mate in question.

Sometimes a merfolk will perform a mating bond with their potential partner(s). This is an ancient ritual that links the participants' souls to each other. A connection which allows one to feel how their mate is doing and for one to follow the other(s) after death as a spirit.

When a mating bond is formed, unique markings appear all over the pair's body. The colors and shapes vary between individuals but only other merfolk can see it. It shows that the mated pair are taken but also share little interest in new partners. Mating bonds must be done willingly between both sides in order to work.

If a merfolk has lost something whether due to a mutation or another unnatural event, a mating bond would restore it to some extent. This even includes lost senses, lost ability to take human form, and for species like sirens they regain their unique power. Selkies gain the ability to regain their missing coat once no matter the location.

There is some human technology that can see mating bond markings if they have lenses made from sea glass. Merfolk and human tattooists are sometimes commissioned to make physical tattoos on the marks. The latter being fishermen or trusted individuals by the former.

Some human communities are aware of the merfolk's existence. They often vary but it's usually people who have occupation that results in moderate sea interactions or have mer partners. It ain't uncommon for lovers of the latter to make life changes.

Whether it's a life on sea following their mate's travel routes or even becoming a merfolk themselves. There is a unique potion made from a merfolk's blood that can convert a human into this unique race. Any who do partake in it becomes the blood donor's species and inherits their genetic traits including mutations from the adaptive gene.

Conversion takes one-two weeks to complete depending on the merfolk in question. This is so the human can adapt to the changes at their own pace without something going wrong. It takes extra time if the blood donor has mutated to a certain extent as they do manifest inherit physical traits.

(Kaiju No. 8) If Soshiro takes the potion then it would take almost three weeks to fully transform. He will become a 73 ft Great White Shark Siren in the Leviathan class and part of the Pseudo Kaiju class like Kafka. This includes inheriting his own bone like mask, bioluminescence alongside his husband's abilities such as electrokinesis on a lesser scale.

Merfolk utilize whatever they can find in their current environment. This even includes human made objects like scrap to lost transportation vehicles. It ain't uncommon for them to remove trash from the ocean with the occasional human help.

None of these sea denizens like polluters especially if it's done on purpose. It ain't uncommon for merfolk to toss garbage back at the offenders or dump it into their boats. Sometimes petty Leviathan class mers stealthily toss garbage island patches on large ships such as military vessels to cruise liners.

Merfolk have their own treasured landmarks and sacred sites of sorts. The species' most important plant is actually mangrove trees. It ain't uncommon for mers to hide their eggs amongst the roots of these trees for they serve as nurseries to orphans.

There are ways for humans to prove themselves trustworthy to merfolk. Whether it's through special charms made from dead mangrove bark, having mating bond marks, or being decently fluent in their language. The latter requires help from a mer in order to learn.

Meanwhile dangers like poachers are taken very seriously. The bones and dead flesh of merfolk are the deepest black in the species' eyes so they can immediately recognize items made from fallen kin. Mers will drown or tear apart threats like poachers without any remorse.

Even baiting them into deep enough water by playing dead, wounded, or unaware. These executions are done in small pods of any size class for maximum efficiency. Abandoned vessels on the sea can be attributed to merfolk attacks.

Items made from mers are given proper burials deep beneath the sea beds. There are rare exceptions to this. If a merfolk willingly donates part of themselves for an item's creation, then the donated materials are treated with a special solution that makes it a different color in merfolk eyes.

The main ingredient for this solution must be given willingly or it won't work. Another natural deterrent against potential threats that try to deceive them. (Not the first time it has happened nor will it be the last.)

(Kaiju No. 8) Kafka gifts Soshiro twin katanas made from a tooth and claw as one of his courting gifts. These blades come with the unique ability to slice even through diamond like a hot knife to butter in skilled hands. Something No. 10 learns the hard way.

Merfolk can live for a very long time compared to humans. Their life span varies between species but some individuals have lived even way longer than what's normal for any individual. Dubbed as Ancients, they are a rarity and often have knowledge that was lost to time amongst merfolk.

What do you guys think?
