About The World God Only Knows

At the start of the series Keima, an avid dating sim player, receives an e-mail offering him a contract to "capture" girls. He accepts what is thought to be a challenge, and a demon from Hell nicknamed Elsee appears. She asks for his cooperation to help her in catching the runaway spirits. These spirits hide themselves inside the hearts of girls, and Elsee suggests that the only method to force the spirits out is by "capturing" their hearts—making them fall in love. Appalled by the idea, Keima refuses after clarifying to Elsee that he is only interested in "capturing" 2D girls and that he detests reality. Nevertheless, with the contract already accepted, Keima would have to help Elsee no matter what; if they fail, both Elsee and Keima would lose their heads.
