Supermarkets are essential to city life, providing families with a safe and convenient place to buy groceries. However, the atmosphere changes completely when evening half-price sales start on unsold bento boxes. In an instant, politeness disappears, replaced by fierce battles where allies become enemies, each struggling for dignity and a meal. The aisles are no longer full of shoppers, but of Wolves and Dogs—the winners and the losers.
High school student You Satou is thrown into this chaotic world after accidentally stumbling into the battlefield. Instead of running from the nightly fights, he wants to join in. Seeing Satou’s total lack of fighting skill, Wolf Sen Yarizui, an older student, brings him and Hana Oshiroi, an eager onlooker, into her Half-Priced Food Lovers Club. Through their training, they learn the real meaning of fighting to secure their food.
