Apocalypse: All my ingredients are S-rank rarities

The Story

Adam Reid faces slow death after being cast out of an S-rank base as useless. In a world plagued by specters, he suddenly activates the Underworld Management System. He now operates the most dangerous restaurant in the wasteland, using S-rank specters as ingredients. His staff consists of tamed legendary reapers. Survival and justice hold no interest for him. He seeks only profit and the fun of watching powerful figures tremble before his establishment.
