Synopsis

Min-Jun Kim was just an average Korean high school student until a sudden summoning hurled him into a fantastical realm. There, he didn't just survive—he mastered the forbidden arts, becoming a formidable dark mage. Wielding black magic, he rose to become the hero who saved an entire world, then promptly left all its fame, fortune, and glory behind, driven by a singular desire: to return home.

Back on Earth, Min-Jun anticipated a peaceful, albeit belated, return to normalcy. But fate, it seems, has a twisted sense of humor. Before he could even unpack his magical baggage, a catastrophic dungeon break rips through reality, unleashing hordes of monsters and shattering his hopes for a quiet life. With humanity under siege and his comfortable future hanging by a thread, the former dark mage hero finds himself in an impossible situation. His only option? To enlist in the military. The very next day.

Will he blend in, or will his dark past spill out and rewrite the rules of enlistment forever? Get ready for an epic saga where otherworldly power collides with the mundane, and the fate of Earth rests on a reluctant hero who just wanted to relax.
