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.
