One Piece: Stirring Up Trouble Across the World, Starting with Being Eavesdropped On

[Starts at God Valley + Stirs Up Trouble Among the Factions + Forms an Organization + Causes Trouble Across the World]

Ze En transmigrates into a treasure chest and becomes a baby.

He thought he had been handed Shanks' script.

But when the treasure chest opened, the one waiting for him wasn't Roger. It was Rocks D. Xebec.

By a twist of fate, he also ate a Devil Fruit, becoming the youngest Devil Fruit User in history.

He thought that as a baby, he wouldn't be involved in any important events.

Little did he know that his Devil Fruit ability had already revealed every last one of his inner thoughts.

Relying on his knowledge of the story, Ze En began influencing the world without even realizing it, starting with the God Valley battle.

One day in the future, at Shakky's Rip-off Bar,

a young Supernova arrogantly asks Ze En what his name is.

Ze En: "You want to know who I am?"

"Then listen closely to my name!"

"I am the son of Xebec, the taster of Charlotte Linlin's breast milk, the man who stole Kaido's Devil Fruit, the savior of the future Four Emperors member Shanks, the witness to the rise of the Revolutionary Army, Whitebeard's unofficial son, the creator of the Okama King, a trainee crew member of the Roger Pirates, Garp the Hero's disciple, and Doctor Imu's enemy..."

"Ze, the King of Causing Trouble, En!!"
