The Strongest Guy’s Big Brother Is an Uchiha

[Oh my gosh, my darlings! As I kept writing, I finally got a little smarter. The early chapters really were too padded, so let me revise and streamline them! I'm working on it now, but it'll take some time, so updates are temporarily on hold.]

At the moment he died at Tobirama's hands while protecting Madara, Uchiha Huan's greatest worry was his younger brother.

Then a voice came to him with an offer: it would send him into the world of Jujutsu Kaisen to give the readers in the "third dimension" a happy ending where everyone survived.

In return, he would be resurrected and reunited with his younger brother.

So, in order to reunite with him, Uchiha Huan agreed to the deal.

But when the other party prepared a body for him, it took into account the Uchiha clan's reputation as a great family with inherited bloodline abilities, as well as their "eye techniques" and other traits... and matched him as Gojo Satoru's [fake] twin brother.

Uchiha Huan: ...Wait, what?!!!!

Fine. A [fake] twin brother was still a twin brother. The most important thing was to hurry up and complete his mission!

So Uchiha Huan sent his shadow clones to take over the Star Religious Group and become its leader, recruiting people and making all kinds of preparations ahead of time.

He also had a shadow clone hire a certain sorcerer and a cursed spirit as bodyguards, accompanying him around Japan to search for Sukuna's fingers.

He even made a shadow clone become Geto's teacher, telling the child all about sorcerers ahead of time and helping him realize that there were many others like him in this world, so he would feel safe... Wait a minute--

As for Uchiha Huan himself, he stayed at the Gojo estate to get close to Satoru and raise his affection for him. He took him out of the estate to meet Geto, helping the two children become sneaky little chickens early!

When they finally defeated Kenjaku and Sukuna, Uchiha Huan's mission was complete, and he could be resurrected and reunited with his younger brother!

But who could have guessed that just as he was about to leave, the two people he had known, spent time with, and protected for over a decade wouldn't let him go?

"I'm your younger brother too, Big Brother. How can you just leave me behind?"

Please note these original elements:

1. The Gojo twins are both the strongest, and the trio will always be sneaky little chickens!

2. The story is 60% Jujutsu Kaisen and 40% Naruto, a slow-burn, long, plot-driven story with a happy ending for everyone.

3. There are dad Gojo and mom Megumi elements, as well as Yuta and Rika elements. The point of view also switches to shadow clones. Since there are too few original characters to use for the Star Religious Group section, there will be original characters to fill it out.

4. The author's abilities are limited, and they don't know much about politics, so the sorcerer society reforms and related content may not be perfect.

5. The manga isn't finished, so some later characters won't appear.

6. This is the author's first serialized novel, and the writing is fairly amateurish, so please read with caution.

Theme: True growth isn't about shining alone, but about learning to accept, understand, and bravely love through one another's companionship.
