After 15 years the MMORPG Infinity Game is shutting down. The games creator, Akira Ono, suddenly finds himself summoned into the game as his character, the Demon Lord Hakuto Kunai. As he tries to grasp his situation, he encounters an injured girl fleeing from a demon king Greol, which he easily defeats. The girl, Aku, explains they are in the Kingdom of Holy Light whose people worship the Holy Church and the angel Cherub. As these are not parts of the original game, Kunai reasons that someone in the game must have tried to summon a real demon lord but accidentally summoned him...
