When he asked Kageyama why Ushijima's spike was blocked and then lost interest, he said he was going to bathe before other people's germs got on him. However, since the word 'germaphobia' is never explicitly used to describe his behavior in the original work, he might just be an extremely sensitive type rather than having a clinical phobia. He is the type to see things through to the end once he starts. He is meticulous not only in volleyball but in many aspects of life, and he says he dislikes careless and unprepared people. He always wears a mask, except when playing volleyball. He has two vertical moles on the right side of his forehead. His weakness is spoiled food. He is part of the 'R-rated group' along with Akaashi, Kuroo, and Matsukawa. He is a volleyball player for the MSBY Black Jackals.
