Keima treats dating sims like scripture, then gets dragged into actual romance where his flowcharts mean nothing. The show's real trick isn't the demon premise, it's watching a guy who thinks he understands women get completely schooled by the fact that real girls have actual wants. By the finale, you realize it's been slowly building something genuine underneath all the comedy, and that's the only conquest that actually matters.

Keima Katsuragi is unbeatable at one thing: dating simulation games. In the virtual world, he conquers every romance route with calculated precision, earning an online reputation as a legendary player. At school, though, he is mocked as a glasses-wearing otaku, and he openly scorns reality in favor of two-dimensional girls. After he accepts an anonymous email challenge, a demon from Hell named Elsie appears and asks for his help. Runaway spirits have escaped into the human world and hide inside girls' hearts. The catch: the only way to drive a spirit out is to make its host fall in love. Keima refuses, but the contract is already binding. A deadly collar ties him to Elsie, and if they fail, both lose their heads. Now the self-proclaimed master of virtual romance must win over real girls in a supernatural romantic comedy.
