A very soft-spoken young boy, Mitsuo usually doesn't like being in big crowds. He only likes to hang out in small groups but regardless, he still doesn't talk all that much.He is very nice and cherishes the friendships that he made in this class. Though he doesn't show it Mitsuo kinda cares about his classmate but doesn't say anything, since he's afraid of being picked on. Also one of the youngest member of the cast

Mitsuo has a soft middle high (unless said otherwise) pitched voice.
