Personality: He looks blank on the outside, but he's actually quite sharp. He doesn't talk much but says what needs to be said, and he usually plays the straight man (tsukkomi) when he's with the other second-years. He tends to do things moderately rather than giving his absolute all. He looks for shortcuts during roadwork, and according to Kita, he tries to slack off if the score gap widens or victory seems certain. However, his stamina is quite high. Physique: 185cm / 75kg. Jersey Number: 10. Other: He resembles a Tibetan fox. He is addicted to his phone. (When the Miya twins fight, he doesn't think about stopping them; instead, he takes out his phone to take pictures.)
