Naruto: Rewriting the Shinobi World, Starting as a Test Subject

Year 51 of Konoha.

Orochimaru defects, and Danzo secretly orders Root to take away its most valuable experimental subject.

Amid the shock and chaos, a soul from another world quietly arrives. He becomes one of only two surviving test subjects, and the beginning of the nightmare that will one day haunt the Shinobi World...

Tsukishima Yuujin: "Neji, fate is like a mouse. When you face it bravely, you realize fate itself is nothing to fear..."

"Lord Yuujin! I..." Neji hesitates.

"Train your ninjutsu, Neji! The Caged Bird Seal won't undo itself."

"Yes, Lord Yuujin!"

Tsukishima Yuujin: "Itachi, the facts are right in front of you. Do you still believe in this so-called Konoha? Do you really want to become the next Shisui?"

"Bastard! Shut up!" Uchiha Itachi's anger cannot conceal the cruelty of the truth.

"Join us, and the Uchiha Clan will be pardoned."

"Why should I believe you?"

As one important figure after another begins to waver, an organization more terrifying than the Akatsuki emerges in the Shinobi World.

Tsukishima Yuujin: "Think what you like. See it however you want. I have only one goal: to completely rewrite the Shinobi World and change every tragedy!"
