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.
