Plot
Keima Katsuragi, a second-year high school student, is an avid bishōjo game player. He is known on the Internet as "The God of Conquests" (落とし神 Otoshi-gami?) for his legendary skills to be able to "conquer" any 2D girl in games. However, in his actual school life, Keima is known as otamegane (オタメガネ?), a derogatory portmanteau of the two words otaku (オタク?) and megane (メガネ?, "glasses"), and is considered nothing but an intelligent yet gloomy geek with glasses.
At the start of the series, Keima receives an e-mail offering him a contract to "conquer" girls. When he accepts it, thinking it is an invitation to a game, a demon from Hell named Elsie appears. She asks for his cooperation to help her in catching runaway spirits: Loose Souls. These spirits hide themselves inside the hearts of girls, and Elsie suggests that the only method to force the spirits out is by "conquering" the girls hearts, making them fall in love with him and filling up the gaps which the runaway spirits hide in. Interested only in video game girls, however, Keima is appalled by the idea, and refuses the assignment as he has no romantic real life experiences whatsoever. Nevertheless, with the contract already agreed, Keima has no choice but to help Elsie no matter what, as they will be beheaded if they fail.
