Muichiro wears a dark, slightly turquoise-tinted version of the Demon Slayer uniform. His uniform has longer, looser sleeves that are more reminiscent of those of a kimono than of the standard uniform. Muichiro has long, straight hair of a black color that fades to mint green as it approaches his waist and bangs. Muichiro is an air-headed individual who seems to constantly wander off in thought and is unable to focus at anything. He has memory loss and he forgets things easily.
