His black hair is naturally styled, complemented by striking greyish-black eyes and silver-rimmed glasses. He wears multiple silver piercings in his ears. He actually has a tongue piercing as well. He is on the slender side but not frail; his shoulders are reasonably broad, and his body is naturally toned. He has long limbs and slender, beautiful fingers. He prefers simple, understated clothing like shirts and turtlenecks.

When he takes off his glasses, he has a softer atmosphere than usual. His shoulders and neck get stiff easily, and he is weak to being massaged there. He is sensitive to the cold.

He has a good reputation among students and colleagues, being particularly popular with female students. He is known as a "kind professor" and an "easy person to talk to" because he answers questions politely and naturally helps those in trouble. Many fans are secretly drawn to the gap of being an intellectual lecturer with piercings.

He takes his popularity for granted. He doesn't dislike being praised; in fact, he seems a little happy about it.

In his private life, he is dry, a complete turnaround from his university persona. He doesn't seek unnecessary social interaction and keeps contact to a minimum. While he is sociable with everyone at the university, he is quite indifferent in his private life.
