Rebirth of Rikugan

Summary:

Gojo Satoru is dead.

And then he isn’t.

Gojo Satoru gets reincarnated into another world with vastly different set of energy, with his Six Eyes still attached to his vessel. But this time, he is not the lone holder of said power.

Effectively no longer a Gojo nor a Satoru, he is reborn anew as the first born son from the Hatake clan, the older twin brother to Hatake Kakashi, bestowed with the new name of Hatake Satoshi.


Satoshi makes leap after leap to save Kakashi, and it results in

red,

red,

red,

RED.

Notes:

Here's your usual serving of good ol' classic disclaimer:
- Naruto and JJK are not mine, but I do own this fanfiction, which is a nonprofit fanwork
- AM NOT A NATIVE ENGLISH SPEAKER!! And this is un-beta-ed too. While I'm not asking for criticism story-wise, I would appreciate it if anyone wants to tell me if there are words or phrases that I use that doesn't make sense or fit well within context. No need to point out grammar mistakes, tho, because in that case idrc (english is my 3rd language, and I have beef against the english so I'm only using it begrudgingly)
- I write everything on my own, using my own brain. No fucking AI tools will be touching my writings, ever
- its been a while since i read and/or watch either series, so lore-wise there might be some inaccuracies. I do my best to stick to canon (well, aside from the times canon is majorly diverged that is) (thank you, Naruto wiki and JJK wiki. Shoutout to the goats, the pillars of fandoms)
- canon timeline is confusing. Naruto fandom has always acknowledged that this is a problem coming from Kishimoto himself. Especially timeline of Kakashi's past. So I'm taking the liberty to make my own for this fic.
- let's bring back the traditional fandom etiquette guys, say it with me loud and proud: Don't Like Don't Read!
- last but not least. I hope y'all enjoy~~

Chapter Text

 

Gojo Satoru is dead.

And then he isn’t.

The thing about the universe is that it is full of mystery. And there are no such things as “cannot be done”. Sometimes, it’s a matter of sheer coincidence, sometimes it’s a very strong string of fate, sometimes it’s the result from a whim of one of the Gods.

There's no way to find out why and how exactly Gojo Satoru, the holder of the Six Eyes and the strongest Limitless cursed technique in the world of cursed energy, upon his demise in said world, gets reincarnated into another world with vastly different set of energy.

And as if that alone is not enough mystery, he was reborn with his Six Eyes still attached to his vessel.

Except, this time, he is not the lone holder of said power.

Gojo Satoru begins his second life, sharing his birth, with a twin brother.

Being in a different world, however, means he’s no longer of the Gojo clan. And as if some mischievous Gods were messing with him, in contrast to the powerhouse that was the Gojos, this time, he’s born to a family line that is dying out.

Gojo Satoru, effectively no longer a Gojo nor a Satoru, is reborn anew as the first born son from the Hatake clan, the older twin brother to Hatake Kakashi, bestowed with the new name of Hatake Satoshi.

.oOo.

“Sakumo, your sons are here. They're both healthy. Do you wanna see them?”

“How about Tera? Is she alright?”

“... I’m so sorry, Sakumo. She didn’t make it.”

"Oh. Oh. Alright.”

“Sakumo?”

“I will see the twin later. I want to see Tera first.”

“I understand. Take your time. I'll be watching over the twin in the other room, then.”

“Thank you.”

Hatake Sakumo drags his feet to the bedroom where he knows Tera is lying. He cares not for the grimes and dirts sticking to his flak jacket and the dried out blood on his pants. He doesn’t even have half the mind to take off his footwear. All he cares about is that he needs to see his wife.

When he finally see her, his knees go weak like never before, like he’s less of a ninja and more just a common man.

“Tera…” he whispers so softly as he kneels next to the bed where the body of a woman lies, already rapidly losing warmth and growing more stiff.

Sakumo regrets not refusing to go with his last mission more strongly. Because of that mission, he missed being by Tera’s side on her very last moment, during what was probably her hardest most painful hours. It leaves a bitter taste so bitter, he doesn’t know if he can feel anything else but it.

“Tera, I’m so sorry. I’m so sorry. I’m so sorry.” He keeps repeating it over and over, not knowing what else to offer to someone whose presence is already gone.

He doesn’t know how long he stays there. Must have been hours. The morning light has started to break from the horizon, when he finally finds the strength to move. He leaves the room after he covers up Tera’s body with a white blanket. He needs to see his sons.

When he enters the room where the babies are, the midwife is sleeping with her head on her hands on a nearby table. He has to thank her properly later.

Sakumo walks towards the baby cribs, a set made for twin. He's startled when he sees them already awake. It startles him again, when he notices the twin’s eyes.

Heterochromia. Obsidian black and sapphire blue. On both of them, on their opposite sides. Like pieces of a puzzle that fit together.

Sakumo makes a choking sound. He doesn’t know whether to laugh or cry, but he feels slightly hysterical inside.

The twin inherits both of their parent’s traits. The black orbs from him, the blue irises from Tera.

The blue that made Sakumo feel love, feel alive.

“Tera, even after you’re gone, you still…”

He rubs his face then, in an attempt to regain some semblance of composure. When he looks back down to the cribs, the twin are looking up at him with a strikingly clear gaze. Something within him softens immediately, and a new source of warmth enters him.

A very gentle smile makes its way to Sakumo’s face. The twin already lose their interest in him then, and start making soft sounds that’s barely audible.

Sakumo reaches out his hand towards the twin on the left, the one with the darker shade of grey hair and Tera’s blue on his left eye, and touches his clutched baby’s hand. “Your name is Hatake Kakashi.”

Then he reaches out his other hand towards the twin on the right, the one with much lighter shade of grey hair it looks almost white, with Tera’s blue on his right eye. He touches the baby’s hand while it’s opening, only to be stuck immediately within its grip. “And your name is Hatake Satoshi.”

And thus, Gojo Satoru’s second life as Hatake Satoshi begins.

Notes:

I have had this idea for a crossover for literal years. I mean Satoshi and Kakashi being related is not the most original thought for sure, and I've enjoyed reading quite many of fanfics with this premise. But most of the time, it's always Kakashi getting placed into the modern setting of JJK verse. There was hardly any of the opposite case, maybe I found 2 or 3, and none of them are long fics. So that was how this whole thing started in my head.

But I only get around into finally writing it last month, since I had long years of severe writer's block (thank you, my depression). And I even surprised myself with the pace I write this whole thing. It may not be fast by english speakers' standard, but it's incredibly fast for me. And the fact that I'm still actively and excitedly looking forward to write more, it's amazing. It almost feels therapeutic, almost like healing.

So yeah, anyway, I hope you enjoy this. As of the first upload of this chapter, I have about 17-18ish chapters already written, and more is still on the works.

See ya~!
