He's generally quiet and distant boy who often speaks his limited vocabulary to onigiri ingredients, due to his powerful cursed technique. Despite his aloof personality, he is truly an insightful and caring person who gets along very well with Yuta Okkotsu after the latter's entrance to Jujutsu High. He's also calm and intelligent in any situation, as well as being fully aware of having a greater amount of cursed energy that he holds for his technique. He can be somewhat playful.
