Driven by a deep-seated resentment born from a shadowy past, his quest will expose hidden identities, plunge him into perilous undercover missions, force him to confront trials of life and death, navigate treacherous betrayals, and wade through rivers of blood.

Meanwhile, in a world teetering on the brink of destruction, Kim Songcheol, the infamous summoner known as the “Enemy of the World” with power at its theoretical maximum, faces an unimaginable foe: an incorporeal demon king who defies the very laws of physics. To defeat this existential threat, he makes a daring decision: he conceals his overwhelming strength and embraces the path of magic. Journeying back from the ‘Summoning Citadel’ as a mere novice sorcerer, Kim Songcheol embarks on a new journey. This gripping tale unfolds as he unravels the enigmatic forces at play, striving to save the world from imminent doom.
