Seafaring: I'm Aizen, a Celestial Dragon, and I'll Found a Nation and Destroy Imu

"No one stands above the heavens from the very beginning! Not you, not me! Imu has sat on that throne for eight hundred years. It's time for someone else to take over!"

Aizen transmigrates into the world of One Piece.

The good news: he becomes a Celestial Dragon, supreme above all.

The even better news: he gets banished from Mary Geoise.

After awakening the King System, Aizen arrives in the East Blue and sets out to build a kingdom of his own.

He spends years making plans, building up approval points, and earning System rewards along the way...

He gets Sosuke Aizen's ability template!

He summons Kuangye Xing, Retsu Unohana, Alucard, Guangtou Qiang, and the Unstoppable...

He obtains an array of powerful technologies, including intermediate-range ballistic missiles, nuclear missiles, electromagnetic cannons, laser cannons, and drone swarms.

On the very first day of founding his kingdom, he takes down a Celestial Dragon!

From then on, trouble keeps coming his way, but...

Akainu: "I couldn't even take a punch from Kuangye Xing?!"

Kaido: "In front of Alucard's Zero Requiem, I'm nothing!"

Shanks: "You bastard, you're telling me the guy chasing me with an axe is just a lumberjack?!"

Aizen: "Imu, taste my Ultimate Blazing Blast!"
