The supermarket is an important structure in each community because it provides a simple method to buy a range of foods in a family-friendly, safe atmosphere. These stores, on the other hand, alter in the blink of an eye when the unsold bento boxes go on their nightly half-off promotions! As each individual struggles for dignity, pride, and dinner, war breaks out and friends become adversaries. In these stores, there are no longer any people, only Wolves and Dogs—winners and losers. You Satou, a high schooler, is cruelly introduced to these clashes after unintentionally wandering into the combat zone, but instead of avoiding these nightly confrontations, he wants to participate in them. When upperclassman and Wolf Sen Yarizui notices Satou's lack of combat abilities, he invites him and Hana.
