The Ugly Emperor Unifies the Seas, Then Invades a Parallel World?

The clown king Buggy reaches the Final Island and learns the world's secrets. He overthrows Imu, ruler of the Celestial Dragons, in one fell swoop, establishes the unified Clown Emperor Empire, and becomes the emperor of the pirate world.

As the Tree of Life that holds back the ocean slowly withers, the sea is about to drown every continent in the pirate world.

To save the world from being swallowed by the sea, in Year 15 of the Clown Emperor Calendar, Buggy uses a wormhole created by Vegapunk to lead an imperial advance team into a parallel world in search of a new sprout from the Tree of Life.

But they discover that this world is a little different...

Zoro: "How can I, the world's strongest sword fanatic, not even beat Mihawk? And I've lost an eye?"

Ace: "What do you mean, I became someone's son just a few years after setting sail?"

Luffy: "You want to become King of the Pirates? The Clown Emperor... wants to be your man..."

Buggy: "I really became King of the Pirates? And united the pirate world?"

Impel Down prisoners: "We were right to follow Captain Buggy! The captain is so powerful!"

King Buggy: "What kind of weirdos are these...?"
