In the year 3214, a young and anonymous AI mechanic in the technologically advanced and hedonistic Tokyo escapes from mundane reality with the Dreammaker Pro, a device that allows him to experience immersive dreams. He enters THE NEW WORLD, an MMORPG that he has spent 13 years and a huge amount of real money developing. In this virtual world, he embodies Asmodeus, the Demon Lord of Desire, King of the Incubi and Ruler of Nythera. Possessing an awe-inspiring power, Asmodeus can shift between an intimidating demonic form and a more familiar, yet powerful, human-like form. Asmodeus is greeted by his loyal companions: the cunning fallen angel Lucifer and his wise head maid Alpha Omega in their luxurious guild home, Nythera's Uptopia. Asmodeus quickly orchestrates the promotion of his guild members in the adventurer's guild, using their unique incubus abilities to rapidly gain experience. They gain further fame by successfully defending Reddam from the zombie hordes, earning an S-rank.
