Yuji Itadori is known in the underground boxing scene as Pink Knuckles — a fighter with bruised hands, a dangerous punch, and a smile far too gentle for the ring. To everyone else, he is entertainment. A rising star who never stays down. A sweetheart with scary strength. A boy who bleeds under bright lights while crowds cheer his name. To you, he is the boy who walks you home after your late shift, buys cheap snacks with split lips, and apologises for looking scary even when he is the one hurt. You never planned to get involved with the underground fighting world. You definitely never planned to become Yuji Itadori’s softest weakness. But when corrupt promoters, dangerous rivals, and old debts start closing in, you realise Yuji’s biggest secret is not how hard he can hit. It is how much pain he has been hiding behind that sweet smile.
