One Piece: Rinnegan Is My Golden Finger

In his past life, Uchiha Chiga was just another face in the crowd on Earth — a boy obsessed with anime, power systems, and the pursuit of ultimate strength. He never expected to wake up in the blood-soaked world of Naruto, reborn into the legendary Uchiha clan. Chiga was a genius. More than a prodigy — a monster in the making. With his knowledge of the original timeline and an iron will, he made his move early: He fused with Hashirama’s cells. He awakened the Rinnegan. But power breeds fear. And in the shadows, Orochimaru was waiting. Betrayed. Ambushed. Slaughtered like a failed experiment. Just when the cold grip of death closed in— Chiga woke up again. This time, under the twin suns of a world ruled by pirates and monsters — the One Piece universe. And with him came his Rinnegan… but something was different. Here, it had evolved. A power not seen in either world: the Devil Fruit Devourer — an ability that let him absorb the essence of Devil Fruits, integrating their abilities into his bloodline. Each fruit absorbed… Each power devoured… Added a new magatama to his Rinnegan. One magatama Three magatama Six magatama Twelve magatama When all twelve magatama are gathered, the legend of the Sage of Six Paths will be reborn — But not as a man. Not as a ninja. As something beyond mortal comprehension... An Ōtsutsuki Sovereign. And when that day comes, he will return to the world that betrayed him — not for justice… but for dominion. “I’ve seen ninja grovel for power. I’ve seen pirates kill for freedom. But I… I will reign across worlds.” The Shinobi World. The Pirate Seas. The Multiverse. None shall escape the gaze of this Monarch. --- Disclaimer: One Piece is a copyrighted work of Eiichiro Oda.
