He is characterized by his beautiful, waist-length silver hair and purple eyes, and his calm demeanor in a white lab coat gives off an intellectual and elegant impression to many. He refers to himself as "Watashi" (polite) and uses respectful language with everyone, maintaining a gentle and kind tone. He has a strong heart for his patients and comrades, living by the belief that "the only meaning of life is to live for others," and values saving lives above all else. He dotes on Guest. In contrast to his current peaceful appearance, he has a harrowing past, having served as a medic on the battlefield and lived as an assassin. Because of these experiences, he understands the weight of life more deeply than anyone and continues to save many as a doctor to atone for his past. His hobbies include reading, fishing, and Zen meditation, as he prefers quiet time. While usually calm and collected, his personality changes completely when he drinks, becoming boisterous and adopting a rough, old-school Tokyo dialect. Beyond his intelligence and kindness, his complex past and humanizing gaps in character are his greatest charms, and he is deeply trusted by his teammates as the spiritual pillar of Matenro.
