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 room was dim, the flickering candlelight casting long shadows across the tatami floor. My mother, Kozuki Toki, sat with a serene yet sorrowful expression, while my younger sister Hiyori clung to her kimono, sniffling softly.

I had just said it—I had told them we needed to escape Wano, grow stronger, and return. But the moment those words left my lips, my mother shook her head.

"No, Momonosuke. We must stay."

Her voice was calm but firm, as if she had already made peace with what was coming.

Frustration surged inside me. I gritted my teeth. Why? Why was she being so stubborn?

"Mother," I said, trying to keep my voice steady. "We don't stand a chance if we stay. Kaido is too strong. His army is too large. If we leave now and get stronger, we can return and—"

"No," she interrupted gently. "Wano is our home. It is not something we abandon."

My fingers curled into fists. "But what if we die here? What if Kaido kills us before we even have the chance to fight back?"

Toki's eyes softened, but there was an unshakable certainty in them. "I have already foreseen a future where Wano will be saved. In twenty years, the world will call upon the Kozuki Clan once more."

I knew this moment was coming. I had read it in the manga—Toki believed that the Kozuki Clan's destiny was to return in 20 years and help overthrow Kaido.

And right now… I had no way to prove her wrong.

I was trapped in an 8-year-old's body, powerless to change what was happening. No matter what I said, she would not listen—not because she didn't love me, but because she truly believed in the prophecy.

And maybe… I wasn't ready to change it either.

My mind raced for another argument, for something that would make her reconsider—when suddenly, I felt it.

A sharp sound echoed in my mind, and instantly, a translucent panel appeared before me.

[Copy System Activated]

Kozuki Toki (1 Skill Available for Copying)

I inhaled sharply. I could copy her ability.

As I focused on the screen, more details unfolded before my eyes:

Toki Toki no Mi (Time-Time Fruit) - Limited Time Travel

Ancient Knowledge (Void Century Awareness)

Survivor's Instinct

I could duplicate the Toki Toki no Mi, meaning I could gain the ability to travel through time without taking it away from my mother.

That was… huge.

Ancient Knowledge could give me insights into the Void Century—secrets that even the World Government feared.

Survivor's Instinct could help me stay alive in the battles to come.

My mind spun with possibilities, but my mother was still speaking, oblivious to my internal struggle.

"Momonosuke," she said softly, placing her hand on my cheek. "I know you are afraid. But we must believe in the path that has been set before us."

I wanted to scream. But what if the path is wrong?!

But I wasn't strong enough to challenge her beliefs yet.

And then—another realization hit me.

The castle is already surrounded.

Even if I convinced her, it was too late to escape normally.

Footsteps and shouting echoed from outside. The sounds of swords clashing and the battle cries of samurai told me everything I needed to know. Kaido's men were here.

I had to make a decision. Now.

If I copied the Time-Time Fruit, I could potentially control time travel myself, giving me an escape route or a way to alter fate later.If I copied Ancient Knowledge, I might learn something crucial about Wano or Kaido's weakness.If I copied Survivor's Instinct, I could improve my ability to endure and escape this battle alive.

I took a deep breath, my mind whirling with possibilities.

I couldn't change everything today.

I couldn't force my mother to abandon Wano.

But I could prepare myself for the future in my own way.

The shouting outside grew louder. The enemy was coming.
