Hanzawa is easily amused. Though he puts on a friendly exterior, he is not an easy person to read. He usually keeps his calm and rarely raises his voice. He is also very observant, noticing and remembering little details about the people around him. Two clubs and his dorm headship in his second year. He teases juniors lightheartedly. He has two gay brothers and is expected to continue the family line. He tends to keep his eyes closed with a smile.
