Doomsday Supply Station: All My Staff Are Total Tough Nuts

In a post-apocalyptic world that reveres heroes and despises beasts, I was cast out of the shelter like worthless trash for lacking heroic status. But fate gave me an unexpected power—the ability to decide the beasts' survival. Seizing this chance, I opened a supply station beyond the city walls, trading the beasts' crystal cores. Through shrewd business and willpower, I turned the apocalypse to my advantage and claimed the pinnacle of life. Now, even S-rank heroes are my employees, proving that true strength goes beyond heroism.
