Katsuragi Keima is 17 years old high school boy, for whom the real life is not particularly interesting. He plays 2D games and seduce the 2D Girls in them. So he became famous as the God of Conquest. One day his life changes dramatically, after completely involuntary he accepts a contract with a girl called Elsie (Elucia de Lute Ima), who was sent from Hell, to capture the souls of demons which escaped from Hell. At that moment Keima understands, that he will never have another way out, but to help her or both of them will lose their lives.
Now this super intelligent young man has to pick up girls so he can chase away the demons from their hearts by taking their place. The task turns out to be hard due to Keima’s almost zero experience with real girls.
