In a world of universal class changes, the world-ending evil god descends on Blue Star, threatening to enslave all life. Humanity gains the ability to change classes into various professions to fight back. Dragon Tamer, once the strongest profession, became worthless after dragons went extinct on Blue Star.Andy Sanford becomes a Dragon Tamer and obtains the Divine Dragon System, allowing him to summon ancient true dragons—creatures of unimaginable power. The so-called “dragons” in this world are merely lesser drakes, degraded beasts with only a fraction of true dragon bloodline.

Lucas Jones gets thrown out of an S-rank survivor base as deadweight. The moment he hits the ground, the Underworld’s Business System awakens, and he opens a restaurant at the end of the world. His ingredients are S-rank anomalies. His staff, once tamed, are the Hell Wardens, the Soul Escorts, and Brewmother herself. Climbing from lowly Underworld Worker all the way to King of Hell, he rescues a desperate survivor base with a single meal, swindles the obscenely wealthy with a single apple, and erases every past humiliation with compounding interest. He isn’t here to survive the apocalypse. He’s here to get rich off it and enjoy every bite.
