When middle school kendo champion Ayumu Tanaka begins his first year in high school, he does not take the expected route of joining the Kendo Club; he signs up for the unofficial Shogi Club instead. His sole motive is falling in love at first sight with Urushi Yaotome—the club's president and only member—and will do anything to get closer to her. However, Ayumu decides not to confess to Urushi until he can beat her in a match of shogi fair and square. Naturally, this self-imposed hurdle is a formidable challenge for Ayumu to overcome, as Urushi is far more experienced at the game and sees through his every strategy. Nevertheless, this does not stop him from praising her looks, her skill, or even her smile, which, coupled with Ayumu's expressionless face and direct approach, makes Urushi constantly blush beet red. Learning more about shogi and the charming player sitting across from him, Ayumu inches toward making his confession with each exciting round they play together—even if it is one pawn at a time! 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 Ayumus 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.
