Robert Cooper was an ordinary person until when he was about to die, he appeared in the ocean, in the middle of nowhere.

What he didn't expect is that he would be sent to another world which was something he believed only existed in the One Piece anime.

Why this happens is uncertain, but he has a theory, and it is related to a Kryptonian super genius who created the system that bonded with him, it is described as: Super Pirate Ship!
