Description

Kyoutarou is a first-yeart at Kiyosumi High School. He was a middle school classmate of Saki and joined the handball club in which he reached the prefectural final for the inter middle championship. After entering high school, he joined the mahjong club because of his unrequited crush on the inter middle champion Nodoka. He is the only male in Kiyosumi's mahjong club. Due to his poor mahjong skills, he only occasionally attracts the attention of Yuuki and serves primarily as the club's errand-boy.

Although he fights off Yuuki's flirting, he likes to repeatedly poke her and is inevitably rewarded with a punch. While Yuuki flirts with him, she also treats him like a dog when he fetches Yuuki her tacos. Between his mediocre mahjong skills, his unrequited crush on Nodoka (and later on Mihoko as well), and Hisa delegating all of the club's heavy lifting to him, he gets mimimal attention and respect.
