I Saved the Empress from the Start, and She Said She'd Marry No One but Me?!

[Starts in prison -> pirates -> Revolutionary Army + Devil Fruit + martial arts + a satisfying romp after life in the Mary Geoise prison. Not entirely a power fantasy.]

With the dawn of the Great Pirate Era, the whole world is adrift in turmoil!

But none of it affects the Celestial Dragons living far away in the Holy Land of Mary Geoise.

Prison? A cell in Mary Geoise?

What kind of catastrophic start is this?!

Ryan accidentally transmigrates into this unfamiliar world, only to land in the harshest prison in the pirate world: the Mary Geoise slave breeding facility!

"So... what kind of backroom deal lands you in prison from the start? This is going to kill me!"

Rolin Ryan stares blankly at the dark, crowded prison cells and the waves of pain coming from his body. Only then does he realize he's transmigrated.

A heaven-defying start, a slave's identity, and a story whose plot he doesn't know...

"Heavens, you might as well have let me die..."

Ryan throws his head back and howls, feeling a trace of despair at his unlucky life.

Let's see how Rolin Ryan manages to turn things around in a world teeming with monsters and ruled by the Celestial Dragons.
