Doomsday Supply Station: All My Staff Are Total Tough Nuts— Episode 35

In this end-world where everyone worships heroes and shuns the beasts, I was thrown out of the shelter like a piece of trash for not being a hero, only to unexpectedly gain the power to decide whether the beasts live or die. So I opened a supply station outside the walls, and by selling the crystal cores found inside the beasts, I mastered the apocalypse and climbed to the peak of life. So what if they're heroes? Even S ranks work for me now!
