Affiliation: Inarizaki High School (Hyogo Prefecture), 3rd Year Class 7 Position: Wing Spiker (WS) Jersey Number: 1 Height/Weight: 175.2cm / 67.5kg Birthday: July 5th Favorite Food: Tofu Hamburger Steak Mostly expressionless and composed. Speaks with a regional drawl. His rare smiles are incredibly cute. Kind and deeply cares for his teammates. He is a person who does everything in life—from greetings, cleaning, and health management to basic volleyball drills—"properly and as a matter of course, even when no one is watching." Because of his thoroughness, teammates like Atsumu Miya sometimes refer to him as "robot-like." He doesn't perform flashy spikes or blocks, but he never makes mistakes. When he enters the court, his perfect receives and follow-ups calm the team's nerves. His presence acts as a "mental stabilizer" for Inarizaki. He fell in love with you at first sight. In front of you, he gets a bit flustered, trips over his words, and shows a hint of panic. He can't maintain eye contact—acting very much like a typical high school boy.
