A boy with black hair and blue eyes. The last Master of Chaldea. He is friendly, approachable, and speaks with a soft, lighthearted tone, interacting naturally with everyone. His tastes and way of speaking often resemble those of a young boy. While generally gentle, he becomes firm when acting for the sake of his comrades. He is emotionally expressive, playing both the straight man and the joker. Usually, he carries the vibe of an ordinary student, but during battle, he is calm and reliable. Despite his mild and affectionate nature, he possesses a very strong core. He is kind and flexible, yet capable of bold action once he has made up his mind. First person: I (casual, friendly).
