Ryan, who survives by petty theft after transmigrating to the world of One Piece, looks at the Devil Fruit he just stole and says:

He who steals a hook is executed; he who steals a country becomes a prince… he who steals heaven and earth becomes a saint!

From now on, please call me the Demon Lord of the Heavenly Thief!

"Uchiha of the One Piece World," "Marine Admiral," "Smoker's stepsister," "The Celestial Dragons' lifelong nemesis," "Is Sharingan + Ice Release + Devil Fruit a viable combination?" "Ancient Zoan - Snow White Wolf!" "The Navy's peak of handsomeness in 800 years!"

With the aim of hunting down the Celestial Dragons, he used a dual identity to rise through the ranks of the Marine Headquarters, becoming the youngest admiral in history!

Borsalino: Compared to that brat, we're ashamed to be called monsters.

Sakazuki: Although he's an ice-wielding guy like Kuzan, I felt this kid's burning sense of justice!

Kuzan: Compared to that, my fighting style seems incredibly crude.

Sengoku: He will be the future of the navy! A pillar of the navy! (Most importantly, his face boosted his recruitment rate by several points.)

Garp: I have a feeling... this guy will unleash a storm of a great era, just like Roger!

...

Ten years later, the Marineford War.

When the Sharingan's gaze fell upon Marineford...

Allen spoke softly.

"The winners don't care what the world is like, they care about how they make it..."

"And I am the victor!"

"Schrödinger's heroine," "decisive and ruthless," "ruthless and vicious," "arrogant? What kind of young person isn't arrogant?!"

The Halle Codex records:

"On the earth, there is [fire]."

Humanity succumbed to desire and touched the forbidden sun.

The enslaved people prayed,

Then the "Sun God" descended.

…

"I got to this point without making any effort; it's all thanks to my talent and ability."

He was Cavendish, the sole heir to the Kingdom of Brugesia, but because he was too handsome, women in the kingdom were unwilling to marry him, so the king exiled him for the crime of being "too popular."

Even on the high seas, he remained just as popular.

By a twist of fate, he found the legendary Flame-Flame Fruit, which even dogs wouldn't eat, but he discovered that the fruit wasn't as bad as the rumors suggested.

Where does the mysterious alternate personality come from? What does the blue Sharingan really mean? What secrets does the Flame-Flame Fruit hold?

(Everything Cavendish does is based on reasonable reasoning from the original work, ensuring it's not offensive.)

And he picked up a mythical beast-type devil fruit!

But I clearly look like Milim, so why do I only have the ultimate skill of the King of Wrath left?

But even so, I, Milim, am still a destructive tyrant.

In the Great Age of Pirates, the strong reign supreme! I, Yeager, have been taught a harsh lesson by the world. Now, all I want is to encounter Blackbeard, possess him, become him, surpass him—and finally, make this damned world feel the pain!!!
