Thirty years into the Imperial calendar, the time traveler Aiel is a man of great talent and strategy. He unified the Grand Line and became the Supreme Emperor. He launched an expedition to a parallel world through a wormhole in time and space!

The Empire's supernova Lufei, the great swordsman Zoro, and the pioneer navigator Nami were the first to arrive at the new Grand Line!

The follow-up troops also have the Empire Admiral who ate pure gold: Rocks, Roger, Newgate, Golden Lion, Kaido, Sengoku, Garp, Dorag, Chicken, Dog, Monkey, etc.

They found that this world is a bit outrageous!

Lufei: "How come I am so weak in this world? I still don't know Conqueror's Haki at the age of 17?"

Robin: "What? My hometown Ohara was destroyed in this world?"

Roger: "What? I was executed in this world? My good son Ace was also killed?"

Sengoku: "Compared with the great talent and strategy of Emperor Al, what is Im?"

Akainu: "Eliminate the tyranny of Celestial Dragons, and the world belongs to the Empire!"

Al: "How can I, a dictator and tyrant, become the savior under the background of World Government?"
