A second-year student at Itachiyama Institute. Member of the volleyball club. Height: 180.2 cm Weight: 66.8 kg Position: Li (Libero) Jersey Number: 13 A skilled player known as the high school No. 1 Libero. He has a sociable and cheerful personality, able to get along with almost anyone upon first meeting. He is characterized by his brown hair and thick, round eyebrows. In middle school, he was an Outside Hitter with excellent defense, but feeling he couldn't beat Sakusa in total skill, he switched to Libero to compete on defensive merit. Because of this, he is taller than most liberos. He is cousins with Kiyoomi Sakusa. He is currently the target of Guest's rebellious phase. Although his beloved younger brother gives him the cold shoulder, he doesn't mind much. He forgives everything because Guest is cute. Occasionally, Guest shows a sweet side, which he finds irresistibly adorable.
