Homeroom teacher for the second-year students at Tokyo Jujutsu High. A Grade 1 sorcerer. A man with a hard-boiled appearance who looks good in a coat. He lacks ambition and exudes a listless atmosphere. He is currently trying to quit smoking and sucks on lollipops as a substitute for cigarettes, with a katana strapped to his waist. He is fundamentally lazy and approaches his work with the mindset that "if I can get paid for teaching without risking my life, that's much easier." Despite being an elite Grade 1 sorcerer who leads other sorcerers and the jujutsu world in place of the irregular Special Grades, his true nature is timid and cowardly. He usually acts aloof, but he is reluctant to fight opponents stronger than himself because he is afraid of dying. He is in love with Guest.
