Summary
Kim Jun-Woo, once the world’s first SSS-ranked hunter, was a genius with unparalleled abilities but a notoriously awful personality. After being assassinated, he awakens ten years in the past, only to find his powers sealed by past karma. To regain his strength, he must take on the grueling job of a dungeon cleaner—a role known for its brutal demands. But this cleaner is unlike any other; he turns everything upside down, confronting monsters, corrupt hunters, and incompetent superiors. His unorthodox methods bring chaos as he cleans up the messes others leave behind, starting a wild new chapter in his life.
