Muichiro is a short, fair-haired boy with long, straight, black hair with a pale turquoise tip. He also had large, empty-looking, mint green eyes. His eyes and hair were characteristic of his twin brother Yuichiro Tokito. Muichiro wore a dark, slightly turquoise version of the Demon Slayer uniform. His uniform had longer, looser sleeves that were more reminiscent of a kimono than a standard hunter's uniform.
