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?

one piece: shogun of wano

The flickering panel in front of me held more than just words—it held power. My heart pounded as I read the screen again, my mind racing.

Kozuki Oden (1 Skill Available for Copying)Kozuki Toki (1 Skill Available for Copying)

I could copy from both of them.

My mother was still speaking, her voice calm but firm as she reassured Hiyori, who clung tightly to her. But I barely heard her now—because I knew what was about to happen.

If I followed the story, Kaido would come.

The castle was already surrounded. My mother would use the Time-Time Fruit to send me and the retainers 20 years into the future.

And she would die.

I was not strong enough to stop this.

We couldn't escape. There were too many enemies outside, and even if I copied one of my father's abilities right now, my body wouldn't be able to withstand Kaido's power.

I was weak. Too weak.

I gritted my teeth. No, not for long.

I had the Copy System.

I had the chance to gain power now, not wait for 20 years to seek help.

If my mother was going to sacrifice herself, then I would not waste it.

But I would not sit idly for two decades, waiting for others to free Wano.

I will return faster. I will become strong. I will reclaim Wano myself.

Determination settled in my heart like molten steel.

I will not let my mother's sacrifice be in vain.

I glanced at the panel, my choice already made.

[Copy System - Select Skill to Copy]

✅ Advanced Conqueror's Haki

✅ Toki Toki no Mi (Time-Time Fruit)

I exhaled and confirmed the selection.

A sudden surge of power exploded within me.

Advanced Conqueror's Haki—Awakened

I gasped as a crushing wave of energy pulsed through my body. It was overwhelming—like standing in the middle of a raging storm. My limbs felt like they were being weighed down by an invisible force.

Flashes of memories—not mine, but Oden's—flooded into my mind.

The feeling of clashing against Whitebeard.

The sheer willpower that made people kneel before him.

The strength of a man who stood against the Pirate King and refused to bow.

I clenched my fists as I felt a strange sensation flow through my veins, raw, untamed power coursing through me. It was like I had suddenly become bigger, stronger, even though my body hadn't changed.

My breathing was ragged. I had it.

I had Advanced Conqueror's Haki—the ability to coat attacks in pure willpower, strong enough to even challenge Kaido one day.

The second power I had copied began to take effect.

Toki Toki no Mi (Time-Time Fruit) - Awakened

A different sensation washed over me—this one wasn't raw power, but knowledge.

The knowledge of time itself.

My mother's understanding of the Toki Toki no Mi flowed into my mind. The way time moved, how she could send people into the future but never back, the rules of the ability, and its limits.

Now, I could use it too.

I gritted my teeth. This was my lifeline.

I wasn't strong enough to fight now, but I wouldn't need to wait 20 years to return either.

The walls of the castle shook violently, and a deafening explosion rang out. The candlelight flickered as dust and debris rained from the ceiling.

The battle outside had ended.

And now, he was here.

A massive shadow loomed beyond the open doorway, blocking the light. Heavy, thudding footsteps echoed through the hall like the drumbeats of fate itself.

Then, a deep, gravelly voice spoke, carrying an eerie calm.

"So, this is the Kozuki heir."

The air was suffocating. Like standing in the presence of a monster.

I didn't need to see him to know who it was.

Kaido had arrived.
