One-Punch Man in the World of One Piece

Also known as Building a Kingdom in the World of One Piece, Becoming the Pirate King, Starting by Recruiting Nami, and I Stole Luffy's Life.

Ever since he was little, Norton had believed he was destined to be a great king.

Naming conquered cities after himself, standing beneath a nearly completed lighthouse and watching merchant ships from across the world sail into his harbor, riding atop a chariot like a god as the crowds cheered...

Reborn into a new life, Norton finds himself in the world of One Piece.

And just like Saitama, he has broken his body's limiter, awakening strength with no upper limit.

Joining the Marines? Norton has no interest. But being a pirate? That might be worth a try.

Norton decides to set himself a modest first goal: follow Big Mom's example and build an empire of his own.

After that comes the throne of the King of the World!

Starting with Nami, Norton assembles the most dangerous pirate crew in history.

Cat Burglar, Pirate Empress, Devil Child, Pirate Hunter, a pet reindeer, the Surgeon of Death... One prodigy after another joins his ranks.

Years later, Norton has built a vast empire spanning the New World.

Naturally, his gaze turns toward the "Holy Land," Mary Geoise.

"I came, I saw, I conquered!"

These words, spoken by Norton upon his arrival in Mary Geoise, are recorded by the World Economy News Paper-and shake the entire world.
