When a dungeon rescue goes wrong, Yul is forced to fight a monster far stronger than himself. He struggles desperately to survive, and awakens a hidden power driven by memories of the hero who once saved him--the ability to design a labyrinth and turn it into a weapon against monsters. Yet monsters aren’t the only threat. Corruption runs deep in this society ruled by powerful and greedy hunters, and Yul must overcome a series of unexpected challenges to become the hero he set out to be. (Source: WEBTOON)
