The Dashing Young Master of the Roger Family

His soul transmigrated into the world of One Piece, where he became Ace's twin brother.

Loy glanced at the three younger brothers trailing behind him. Every one of them was a handful.

His eldest younger brother, Ace, ran wild everywhere, picking fights with anyone he met. He might as well have pointed at people and said, "I'm the Pirate King's son. If you've got the guts, come cut me down!"

His second younger brother, Sabo, had turned his back on a life of nobility. Brainwashed by Dragon, he joined the Revolutionary Army and spent every day fighting the World Government.

His third younger brother kept shouting that he wanted to become the Pirate King. Heaven help him, couldn't he see that the last person to become Pirate King had already been brought to his knees?

As the big brother of these three, Loy felt that life wasn't worth living. Fortunately...

He was bound to the "Refined Young Master" System.
