Cast out by his own family as useless, Justin Lowe opens a supermarket in the apocalypse and staffs it entirely with S-rank anomalies. His monsters clock in, follow orders, and keep the shelves stocked while human survivors trade hexcoins for goods that shouldn't exist: prehistoric snacks, high-tech weapons, supplies from no known supply chain. Each transaction upgrades the store. Each upgrade unlocks something stranger. The anomalies are terrifying everywhere except inside Justin's shop, where they are, inexplicably, perfectly obedient. Dragged repeatedly into the power struggles and crises of the survivor world, he navigates each one with wit and nerve rather than force. In the end, it isn't a weapon or an army that defeats the cosmic evil bearing down on what's left of humanity. It's a commercial contract, and the man who signs it becomes the world's last savior.
