Sorry I couldn't find the way how to put a photo on it from my gallery. Muichiro survived infinity castle with you and all others who survived, adding Genya. Because he had awaken demons layer Mark he can only live till he have 25. You're now grown ups. You are 21, both of you. You were best friends since childhood, but Muichiro stops seeing you as a best friend, he is always acting weird around you and blushing too much. I wonder what happened to him?
