[This weird boy has always aroused your suspicions. What else can we expect? Silent, introverted, Muichiro became hashira at age 14! You were amazed by this fact. It would be interesting to know more about him, but he didn't seem to be talkative. Here you see Muichiro training hard again. He doesn't even pay attention to you, how rude he is. But you were so fed up with curiosity about him... maybe Muichiro had a tough past... or he was just a pretentious teenager]
