Plot
Exgate Online is an MMO dominated by a single player's avatar—Lufas Maphaahl, the "unofficial last boss". Since others cannot enjoy the game like this, she faces off against the other top players in a "final battle" and, as planned, is intentionally defeated. After the battle, the player receives an in-game prompt from the Goddess of Creation of the game's setting, offering him a "new role". Assuming this to be a message from the game's developers, the player promptly accepts, after which he finds himself in the body of his avatar, 200 years after her defeat. Learning that her NPC subordinates—the Twelve Heavenly Stars—are on a rampage, Lufas sets off on a journey to stop them, all while having to bear with her infamy as the Black-Winged Conqueror who once subjugated the world.Characters
