Muichiro has fair skin and short stature with a lean muscular build along with long, straight hair of a black color that fades to pale turquoise as it approaches his waist. 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.
