One Piece: Rinnegan Is My Golden Finger. Synopsis;

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.
