One Piece: Unbelievable! All My Roommates Are Admirals

Bain drops dead at his desk. When he opens his eyes, his whole world has been turned upside down: he’s transmigrated into the world of One Piece, surrounded by monster-level prodigies. There’s an obsessive 12-year-old who has mastered the Six Powers, and a cold-faced boy who joined the Prodigy Training Camp at nine. Luckily, Bain has a cheat of his own: the Justice Merit System. He can drift around the seas and earn System rewards just by taking down pirates along the way. Before long, Bain realizes that he’s the strongest monster of them all. Akainu: “I always thought I was the true genius, until I met him.” Kaido: “People call me a monster, but next to him, I’m no different from an ordinary man.” Imu: “It’s not that the Five Elders are weak. He’s just too strong.”
