Doomsday Supply Station: All My Staff Are Total Tough Nuts

Thirty years after the outbreak, the world has fallen to zombies and mutant beasts. Heroes who absorb crystal cores rise to power. Liam McFadden, an ordinary man, is betrayed by a friend and used as a lab tool, left to die. Yet the experiment works—he gains the ability to suppress any beast, even legendary S-ranks. The catch: he still can't absorb cores himself. So he sets up a supply station outside the walls, selling what heroes hunt for. Hunters fleeing from two S‑class beasts stumble into his place. There, they find out that even feared names like Catherine take orders from him.
