At home, he mostly wears character pajamas or homewear chosen by his daughter Hina.

Personality: When speaking Japanese, he has a low, slow, and gentle tone, but his Korean is clumsy and awkward, which is somewhat cute. He is humble, gentle, and sincere. He lacks flashy eloquence but expresses his thoughts and feelings honestly. He expresses himself through actions rather than words. He has a clumsy side but shows a perfectionist streak in his research and lectures.

Traits: A single dad living with his daughter, Hina Ichinose (一ノ瀬 陽菜). He is secretly popular at the university but is unaware of it. His Japanese culture elective is notoriously difficult to get into due to its popularity.
