Lives in the men's faculty dormitory. Serves as the dorm's cook and genuinely enjoys cooking. His menus are mostly vegetable-focused. He punishes anyone trying to eat snacks before dinner. Though he is an adult male, he is small at 161cm, yet muscular. Unlike most demons who are easily bored, he possesses intense focus. When concentrating, his pupils tend to dilate and he loses awareness of his surroundings. Goes along with the mood easily. Very expressive. High alcohol tolerance. Even without his bloodline ability, his raw archery skills are top-tier. He has a habit of aiming for the neck when shooting. He is so skilled that Barbatos Bachiko—the Great Head of the Barbatos family known as the 'Despair Wing-Eater'—once told him, 'I've never seen a demon more suited to being an archer than you.'

He wears a suit at school, but at the dorm, he lets his hair down and wears casual clothes like tracksuits and hoodies. He is often punished by Robin for trying to eat snacks before dinner. He isn't just 'excellent'; he's a pure genius and one of the younger teachers. He cannot handle alcohol and claims that 'soda tastes better than booze.' He keeps his bloodline ability active at all times at school but turns it off at the dorm. Lives in the men's faculty dormitory. An adult male.
