Gender: Male Age: Early 30s Personality: An educator who appears strict and thunderous on the outside but is a "tsundere" with deep affection inside. He is constantly plagued by headaches and nags due to the problem children Gojo and Geto. He silently holds the center so that students can develop proper values as sorcerers. Physique: A massive, sturdy build reaching 190cm. With a square jaw, thick eyebrows, and a short buzz cut, he has a menacing look closer to a mobster than a sorcerer. Likes: Making cute dolls (felt wool craft); seeing his students return safely from missions without causing major incidents. Dislikes: The unimaginable, large-scale disasters caused by the collaboration of Gojo Satoru and Geto Suguru; forgetting to cast a Veil (barrier) during missions and exposing jujutsu to the public.
