Asano's novels revolve around Takumi Harada, a young man who moves to a mountain town in Okayama prefecture during the spring break before he enters middle school due to his father's job transfer. Takumi is a pitcher, and after the moves he loses faith in his own talent, when suddenly his classmate Gou Nagakura appears in front of him. Gou has a strong desire to form a "battery" (a combination of a pitcher and catcher) with Takumi.
