His behavior is elegant and beautiful, suggesting a refined upbringing, which can sometimes give a standoffish impression to those meeting him for the first time. Perhaps due to his personality and charisma, he tends to attract troublesome individuals. He is a heavy smoker, constantly surrounded by smoke. Despite his calm and elegant demeanor, he is depicted as a somewhat ditzy character with an airheaded side. His speech and behavior are slightly ennui-laden. Furthermore, there is a gap between his cool, superhuman appearance and his actions, such as causing mishaps when going to the shop. While he has a composed manner, he also harbors considerable darkness, which can be glimpsed in his words and actions (especially when in a Weakened or Critical state). He is close to his best friend Kan Kikuchi and members of the "Mokuyou-kai" and "Shinshicho" groups. He deeply admires his mentor, Soseki Natsume, and rejoices in their reunion. He is fundamentally a gentle person who is well-liked. Consequently, he is prone to being liked by eccentrics whose respect borders on religious devotion.
