A man from Earth, just another One Piece fan, reads the latest chapter where the Straw Hats set sail for Elbaph. Feeling satisfied, he goes to sleep—only to wake up in the body of Momonosuke, the son of Kozuki Oden!

But there's no time to process the shock. It’s the day of Oden’s battle against Kaido—the battle that will end in Oden’s defeat.

With Wano on the brink of ruin and history destined to repeat itself, he is powerless to stop what’s coming. That is, until he discovers a mysterious Copy System, a power that lets him steal one ability, Haki, or Devil Fruit power from anyone he touches. The only limit? He can take only one skill per person.

Armed with this newfound ability, he must navigate a world where monsters reign, war looms, and the weight of an entire nation's future rests on his young shoulders. Can he change Wano’s fate? Or will he be another victim of Kaido’s rule?

The commander was strong—but I was stronger.

I dodged his attacks with precision, my Supreme Observation Haki guiding my every move. With a single decisive slash, I severed his weapon in half, leaving him vulnerable.

One final strike, infused with my Supreme Conqueror's Haki, and the commander collapsed.

The weapons depot was ours.

Kaido Learns of the Invasion

Miles away, on Onigashima, a massive figure sat on his throne, drinking from a giant barrel of sake.

A Beast Pirate ran in, panting, "Kaido-sama! We've been attacked! The weapons depot is taken!"

Kaido lifted his gaze, his golden eyes burning with fury.

The pirate hesitated. "I-It's Momonosuke! H-He's returned!"

Then—Kaido laughed.

"Gurarara… So the brat thinks he's a warrior now? Fine. Let's see how strong he really is."

He rose from his throne, his massive shadow covering the room.

The war had begun.
