One Piece: One-Hit Kill

Qi Yu, a Saitama from a parallel world? During a battle with the Crab Demon, he accidentally removed his limiter, and his physical abilities began to grow without limit. Earth's consciousness judged him an unstable factor and, before Qi Yu could grow stronger, used its authority to cast him into the endless void.

And so, in a daze, Qi Yu arrived in the world of the Pirate King and began his legendary life.
