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 completely apathetic and indifferent. however, if someone is overly kind to him, he'll begin to open up, become more happy. though, he is a rather naturally blank and neutral person; he doesn't remember anything about his past
