In the urban landscape, supermarkets are essential hubs where city residents can safely and conveniently purchase groceries. However, when the evening half-price bento sales begin, the atmosphere shifts dramatically. Politeness disappears, replaced by intense skirmishes where alliances dissolve into rivalry, all in the struggle for survival and sustenance. The once orderly aisles now host only two groups: the Wolves, who emerge victorious, and the Dogs, who are left behind.
High school student You Satou finds himself thrust into this chaotic world after accidentally joining the fray. Instead of fleeing the nightly conflicts, he chooses to participate. Observing Satou's complete lack of combat skills, Wolf Sen Yarizui, a senior student, invites him and Hana Oshiroi, an enthusiastic onlooker, to join her Half-Priced Food Lovers Club. Through rigorous training, they come to understand the deeper meaning behind fighting for their meals.
