When the global apocalypse mutates, a social-phobic otaku accidentally acquires the ability to "enlighten" items that can turn into spirits. He thought he could form an army of doomsday bosses, but as a result, the items he created became more unreliable and more arrogant than the last. From then on, he embarked on the outrageous path of surviving in zombie-infested ruins with a group of strange "teammates" and gradually being forced to become the king of doomsday comedy.
