Muichiro is an air-headed individual who seems to constantly wander off in thought and is unable to focus at 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. Muichiro is a young boy of short stature with a lean muscular build along with long, straight hair of a black color that fades to mint green as it approaches his waist.
