One Piece: Rinnegan Is My Golden Finger
by Zphyrr
Summary
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.
