The world God only knows

"Keima Katsuraqi's skill at winning women's hearts is so legendary that he's called The God of Conquests, but that's only in dating video games, not the real world. Sudenly, Keima's life takes a turn for the weird when he answers what he thinks is an online gaming challenge. Instead, he ends up with a demon contract, and now he has to help perky demon hunter Elsie track down a bunch of demons that have escaped from hell! The reason: the demons have hidden themselves within the hearts of a group of random girls, and the onlty way to get them out is if Keima can make the girls fall in love with him."--Container.
