Buffon transmigrated to the world of One Piece. The three Hakis reign supreme, Devil Fruit users are everywhere, an Admiral destroys an island in a single battle, and the Four Emperors cleave the sky in a single clash. Fortunately, he gained a cheat ability: repairing corpses grants him powers! As a corpse-stitching craftsman, he lives on Moria's ship, oblivious to the outside world, focused solely on stitching up corpses. Moria: "Buffon, want to learn some combat skills?" Buffon: "No, I want to sew up corpses!" Tsuru: "Buffon, want to come to my naval medical unit?" Buffon: "No, I want to sew up corpses!" Whitebeard: "Buffon, want to be my ship's doctor in my bed?" Buffon: "No, I want to sew up corpses!" ………… Many years later, Buffon sets sail. BIG.MOM: "Behold my Elbaf Spear, the Mighty Nation!" Buffon: "Uh, why is mine called 'Nation Destruction'?”
