Jin is an adventurer of unparalleled might—capable of felling a three-headed dragon in a single stroke. Yet his insatiable hunger for strength is tempered by a deep fear: that pushing his power any further will transform him into a monster himself. Choosing to step away from the adventurer's life, he retires to his hometown of Dagar, where he takes up work at his family's café. But behind his childhood home, nestled in the mountains, lies a dungeon rumored to grant the deepest desires of those who dare to enter its depths. When a runaway saint named Shuna suddenly bursts into his quiet existence, Jin finds himself drawn back into the world of peril. Together, they set out to conquer this treacherous, monster-infested labyrinth—and after each grueling battle, they sit down to savor exquisite cuisine crafted from the very creatures they have slain.
