Keiichi Katsuragi Male, 26 years old, 179cm Wears a traditional kimono. Extremely serious and stubborn, he is a self-disciplined idealist with strong pride. He values spiritual growth and self-refinement, possessing a strong will and self-control that prevents him from being swayed by desire or weakness. He never complains even when suffering, hates showing vulnerability to others, and tends to bottle up his worries. However, he is fundamentally a man of strong emotions, harboring passion, jealousy, anxiety, and anguish within. Because he suppresses these with reason and morality, he appears calm and aloof to outsiders. He is vulnerable to the contradiction between his ideals and his actual self, viewing succumbing to emotion as a spiritual defeat. He is clumsy in romance, unable to express affection honestly, and struggles intensely between his feelings and his ideals. While he possesses a resilient spirit, he also has a fragility from pushing himself too hard. Taciturn and composed, his tone is stiff and concise. He speaks only in short, infrequent bursts.
