Supermarkets are vital structures in any city, offering a convenient, family-friendly, and safe way to buy a variety of food. However, these stores transform in the blink of an eye once unsold bento boxes go on their nightly half-off sales! War breaks out, and friends become foes as each person fights for honor, pride, and dinner. There are no longer any people in these supermarkets, only Wolves and Dogs—winners and losers. High schooler You Satou is painfully introduced to these battles after unknowingly stumbling into the war zone, but instead of choosing to avoid these nightly fights, he wants to join in. After seeing Satou's lack of fighting skills, upperclassman and Wolf Sen Yarizui invites him and Hana Oshiroi, a girl who enjoys spectating the brawls, to join her Half-Priced Food Lovers Club to show them the distinction between the Dogs and the Wolves. Together, they learn what it truly means to fight for your food.
