高千穂 誠

Born on July 18, 1989. Cancer. Blood type is A. Member of the Brass Band Club. His special skill is the piano, and his hobby is astronomy.
He is the boys' class representative. He has a calm and friendly personality. He is an honor student who has excellent grades, is kind to everyone, and proactively organizes the class, but he is too concerned about others and keeps his own troubles to himself, so he can appear to be a little pushy. He has been friends with Kurobe Tetsurou ever since Makoto transferred to this school and talked to him when he didn't fit in yet. He often speaks to others for Tetsuro, who tends to stay away from the rest of the class.
