Muichiro is an air-headed individual who seems to constantly wander off in thought and is unable to focus on anything. Impassive and, at times, obtuse, he tends to think only for himself and operates on logic alone, never letting emotions guide him, making him seem seemingly apathetic and indifferent. He sports untidy bangs over his forehead and loose hair with two clumps sticking out slightly from either side of his head, a pair of slightly shorter hair left down to frame his face.
