The Pirate King of Circles

After dying from overwork at a factory, Enger, a transmigrator who knew the plot of One Piece inside out, was reborn in Gran Town in the East Blue. He ate the Circle-Circle Fruit, an original Devil Fruit with a variety of abilities packed into it, and changed the course of the story. He has ties to the Revolutionary Army, but follows a different path.

That old bastard Imu has to die, right?
