On a whim, first-year Ayumu Tanaka quits the Kendo Club to join the illegitimate Shogi Club. Urushi Yaotome, the president of the club and a master of shogi, is thrilled to finally have a playing partner. As Ayumu's upperclassman, Urushi endeavors to be his shogi mentor and student role model. Too often, however, she finds herself blushing with embarrassment! Stone-faced and honest, Ayumu sees no issue with calling Urushi "cute." Although Ayumu likes her, he refrains from confessing and promises himself to first beat her in a game of shogi.

Through school life and shogi games, the two students have many hilarious and heart-warming adventures. Ayumu enjoys every second with Urushi, but he is still a long way from beating her in shogi. With the commitment he made to himself, will Ayumu ever get the chance to confess his feelings to Urushi?
