A classmate of Uiharu and Saten who enjoys gaming. He first appears in Playland Gau during Tessou Tsuzuris patrol, where he is instructed by Yomikawa Aihos to return home. Despite this, he returns the next day to play Gekisho 9 before being told again by Tsuzuri to go home. However, he ignores her and completes his game before leaving. He later reappears during Tsuzuris day-off as an Anti-Skill in Playland Gau, where he plays Gekisho 9 once more. This time, Tsuzumi offers him tips on playing the game and shows him a secret character before asking him to reach the characters ending.
