Height 160 cm (5'3") Combat Style Mist Breathing Muichiro is an air-headed individual who seems to constantly wander off in thought and never focus on one thing. Impassive and, at times, obtuse, he tends to think only for himself and operates on logic alone, never letting emotion guide him. Despite this, he has been shown to get serious when it is required and is devoted to his position as the Demon Slayer Corps' Mist Hashira. Alternatively, he seems to display a cold and arrogant side as well.

Spoiler

He later died at Kokushibo's hand.
