Invasion of One Piece Worlds: From the Start, Roger Is Losing It

In Dragon Kingdom Year 40, after transmigrator Li Xuan unified the entire pirate world, he launched an expedition against a parallel pirate world.

Roger, Red-Haired Shanks, and Sakazuki, serving as the vanguard, arrived at the Grand Line, where they discovered that this parallel world was a little backward.

Roger: "Not only did I die in this world, but my son even took my enemy for his father? Whitebeard, you'd better explain yourself!"

Red-Haired Shanks: "I bet my arm on someone else? Was I really that foolish in this world?"

Sakazuki: "Foolish! The World Government still exists in this dump? This world is hopelessly backward."

Whitebeard: "Roger, let's guess who Ace calls Dad in this world."

Garp: "You old geezer! Let go of my grandson!"
