Fuinjutsu Theory - Hiraishin

Study of the Hiraishin and differences between Tobirama's and Minato's, with a bit of plot, ups!

"So what's the difference between the Nidaime Hokage's Hiraishin and your father's?"

The question took Akira by surprise, Han wasn't usually interested in hearing about him talking about Fuinjutsu, when Akira would have one of his bouts of inspiration that would lead him to sit for hours sometimes days to think and structure the new seal he had come up with, Han would usually find something else to do or just leave.

"Why do you ask?" He asked back curiously. Regardless of the answer he would still explain to him of the differences of the Hiraishin.

"The Hiraishin is the jutsu that killed more Iwa ninja during the last war, I want to know why your father's was more feared than the Nidaime Hokage's."

"You mean other than because my father used it more" He added, he couldn't help but wonder if maybe Han was just asking because Onoki had ordered him to do so to find out if there was a weakness. "Are you going to explain it or not. I thought you loved throwing up Fuinjutsu on people, you've done it to me enough times" Han grumbled and it was clear that this wasn't something he wanted to do but that his grandfather had ordered him to do it.

If Onoki wanted to know about the Hiraishin he could have asked Akira himself, he would have told him. Not that anyone in Iwa would be able to come close to the masterpiece that was the Hiraishin.

"I never said I wasn't going to tell you, I was just surprised by the question" He liked Han, was direct, something rare to find in most shinobi. But by some miracle of Kami most Iwa shinobi were direct and stubborn. So even if their villages were enemies he still liked to sneak into Tsuchi no Kuni to hang out with Han.

"To begin to explain the differences of the Hiraishin of the Nidaime and my father it is necessary to start with, what is Hiraishin?"

Han groaned at hearing that but didn't interrupt him, this explanation would be long and it was obvious Han would rather they were doing something else.

-The first thing: A prerequisite for the Hiraishin to work is that the user must be a sensor, I'm not talking about a simple sensor, but a high level one, otherwise the Hiraishin is impossible to perform.

-Now let's move on, the Hiraishin is a space-time Fuinjutsu. Which means that it is a seal that allows us to interact with the space around us in a certain way in a different space of time than would normally be necessary.

"Now explain it in a way that I understand" Akira gave Han a pout but continued explaining.

-All right, I'll give you an example: -Let's say I have to go somewhere. Let's say I start at A, go through B and arrive at C and it takes me one minute to go that way. A->B->C

-But with the Hiraishin, if I already have a seal mark at point C that means I go from point A to C without passing through B and it takes less than 1 second. A->C.

"Now that you understand that, because you do understand that, right?"

"I'm not stupid Akira, the problem is that when it comes to Fuinjutsu you speak in another language."

"No what happens is when I talk about Fuinjutsu I'm either talking to someone who knows what I'm talking about or I'm ignored, which is what you always do."

Han rolled his eyes. "Fuinjutsu is not the reason I hang out with you."

"I don't like you for your brains either. Now let me continue, you're the one who asked."

"Not because I wanted to."

"I know. Let's continue"

-Now that you know what a space-time seal is, it is time to explain the basis of the Hiraishin, the original seal of the Nidaime.

-What most people don't know is that the Hiraishin is not a single seal as many people think, but two. And these work through the Queen Bee system.

-The Queen Bee system is a sealing system under which the seals work as a team, in which a main seal that functions as the leader interacts and communicates with other secondary seals that obey the orders.

-Here let me draw it for you so that you can understand it better.

-The main seal of the Hiraishin is placed on the user, while the secondary seals...

"They are put on the Kunai" Han guessed.

"Exactly, you're beginning to understand."

-The main seal indicates who should be transported and the secondary seals are by how many you indicate where they should be transported to.

But how does the seal know when to activate or which of the kunai to teleport the user to?

Akira laughed, it seems Han was getting into this, maybe there was still hope and he could get Han into the complicated but fascinating art of Fuinjutsu.

"That's a very good question and it's from here that the differences between the Hiraishin begin, remember I said it was necessary to be a sensor ninja?"

Han nodded.

-Well the first model of the Hiraishin the Nidaime’s worked through his sensory ability, the Nidaime was able to teleport to any of the kunai marked with his seal that was within his sensory range creating a path of chakra from him to the seal he wished to teleport to.

-However this had a couple of flaws to begin with his teleportation was very slow compared to my father's as he needed to create the chakra path beforehand and was limited to his sensory range making him unable to teleport to kunai that were outside of it.

-So the Nidaime's teleportation process can be summary on, choose which kunai with a seal he wanted to teleport to, create the chakra path to be connected and at the moment he is connected with the kunai is when the teleportation takes place.

"And from what you're saying your father's Hiraishin consisted of improving on the existing one."

"Exactly, you seem to be starting to like this" He said mischievously, Han averted his gaze in embarrassment.

-Now let's talk about the improvements my father made, the first thing was to adapt the original formula so he would be able to use it since the previous one was customised for the Nidaime. From there he added the upgrades.

-My father tried to speed up the teleportation by speeding up the creation of the chakra path within his sensory range and after he did that, he decided it was still too slow, so he improved it again and improved it again.

-So, until he decided that it was still too slow, he threw that method away and decided to create a parallel pocket dimension that he could use so that he would always be connected to the secondary seals on the kunai.

-And from there-

"WAIT WHAT, Akira come down to earth!" Han interrupted. "What the hell is a parallel pocket dimension!"

Akira looked with confusion at Han. "You know a space separated from our timeline and stabilized with fuinjutsu anchored with my mother's adamantine chains in the web of space-time."

"Oh, right now it all makes so much more sense" Han said sarcastically then his fist slammed into the ground creating cracks in it. "That shit you just made that up!"

"Just because Iwagakure's fuinjutsu can be summed up as “kunai puts on seal and seal absorbs kunai”, doesn't mean that fuinjutsu is so backward elsewhere. I remind you that Uzumaki were exterminated because our Fuinjutsu," said Akira with a threatening tone.

That silenced Han. Akira preferred not to bring up my clan was exterminated card, but sometimes it needed to be brought up and being accused of lying about fuinjutsu was one of those times. "Now let's move on."

-After creating that pocket dimension my father realised that he had to modify the Hiraishin's main seal so that during the brief moment he passed through that dimension he would not die when his body was forcibly removed from the timeline and returned to it in a few milliseconds.

-He could have been torn to pieces if he hadn't, after that all my father had to do was modify the main seal so he could be always connected to the secondary seals all the time no matter how many he made and he would never have a problem choosing which one to teleport to or when he wanted to teleport to.

-Along with that he had to modify the main seal again to be able to transport other people.

-That's not to mention that unlike the Nidaime my father wouldn't have to worry about how far away the seals were since the pocket dimension always existed meaning that distances didn't matter.

"And that's how the Hiraishin works and what are the differences of it between the Nidaime's and my father's. What do you think?"

"You're insane. What kind of deranged Kami came up with the idea that it would be a good idea for people like your father or the Nidaime Hokage to exist, what do they throw into the water in Konoha?"

"Hey, that's offensive, I haven't even told you the extent of the Hiraishin's formula."

"The extent of the formula?" Han asked with a hint of fear.

"Yes, you know, the space taken up by the sealing formula written in full."

"I know I shouldn't ask but...how much is it?"

"Well," Akira put a hand to his chin. "The original Nidaime formula was placed on a large sized scroll meaning it's about three meters wide while the length of the scroll was about twelve hundred meters, which is three thousand six hundred m²"

"You're killing me" Han complained.

Akira continued as if he hadn't heard him. "Whereas my father's with all his upgrades and customization for him comes to about three thousand meters and it's set on a large scroll just like the original which means it takes up about nine thousand m²"

Akira looked at Han, now he had really finished the Hiraishin's explanation, he was curious what Han had to say. It was quite nice to have someone ask him about fuinjutsu and he always liked to share it, he usually only had Jiraiya to talk to about it so being able to share it with Han was great.

Han didn't respond in the way Akira expected, he had expected Han to react by complaining that this was absurd as before, instead he got up from where he was sitting and started to take off his armour.

Han's armor was heavy and complicated to remove, composed of separate plates and with his great height Han was as always a strange sight, completely unlike what ninjas were supposed to be.

"What are you doing?" he asked suspiciously.

"You've bombarded me with the most insanity I've ever heard in my life, I need to not think for the next six to nine hours" Han's chest armour and arms dropped to the floor.

"Oh!" He exclaimed knowing what Han wanted and mimicked him by taking off his clothes. "Then we are gonna fuck each other's brains out. I like that" He hoped Han would ask about Fuinjutsu again, maybe next time he would tell him about the improvements he had made to his version of Hiraishin.

"I'll start" And with that said Han dropped the kama from his armor.

I decided to take Han as the other character because the guy is the most overlooked jinchuriki and deserves more love luckily Akira is there for him. If anyone wants the explanation of the Hiraishin without the whole Han and Akira thing ask and I'll put it.

Which is your opinion?

I also made some memes.
