One piece: I have Sukuna abilities

In the world of One Piece, Toshiro Arai, an emotionless boy, finds himself on a small island after death. He eats a devil fruit labeled 'Hito Hito No mi model: Ryomen Sukuna - the king of curses', gaining incredible powers. Stoic yet observant, he navigates the chaotic world of pirates and marines. how is Toshiro going to act in this world ? Toshiro, hands casually tucked into his pockets, shot a glance at Akainu and said with a smirk, 'Shall we start cooking?' ps: This is my first time writing anything, btw. Please inform me if I made any mistakes. Also I don't own One piece, obviously, nor do i own anything else mentioned or referenced except for my OC's.
