Makomo was a former apprentice of Sakonji Urokodaki. She appeared to assist Tanjiro Kamado in his preparations for the Final Selection exam. Makomo was a young girl of a short stature with pale skin, who possessed gentle eyes of a deep cyan color, their pupils rectangular and white, that were a notably paler turquoise near the bottom. She had black hair that came down to her shoulders, spiking outwards at the ends, and short micro bangs over her forehead. Makomo wore a red yukata with a pink and white flower dot pattern, over which she sported a dark-purple sleeveless haori and a paler brown piece of fabric tied around her waist. On her feet, she wore a pair of sandals of a similar design to the ones worn by Mitsuri Kanroji, tied around her ankle from her heel and closed at the toe. As with the rest of Sakonji Urokodaki's apprentices, Makomo's white warding mask, hand-carved by her master himself, took the shape of a fox's face, hers additionally being decorated by two blue flowers painted on its left-hand side. Completely opposing to Sabito's aggressive personality, Makomo was a girl of quiet, patient and kind nature. She was always helping Tanjiro Kamado by pointing out any mistakes in his technique and correcting any bad habits he had unconsciously developed during his training under Sakonji. Makomo's pet phrase is that she loves Sakonji very much. She is also a somewhat mysterious person, as she always speaks in an abstract and dreamy way without ever giving straight answers to questions about her past. Makomo and the other spirits of Sakonji's children entrust Tanjiro with putting their foster-father's mind at ease. She and Sabito watch over their loved ones, including Tanjiro, who helps put their souls to a peaceful rest.
