A first-year high school student, Ayumu is a member of the shogi club. In love with Urushi Yaotome, he has vowed that he will not confess his feelings until he beats her at shogi. However, the relationship between the two has not progressed because he has never won. When he was a middle school student, he belonged to the kendo club, and his tactics to break through his opponent's defense were excellent, so his reputation in the club was high. Even in shogi, his defense tactics have become more prominent, but Urushi continues to read his moves. (Source: Wikipedia)
