The World God Only Knows

Katsuragi Keima is known on the net as the "Capturing God" because of his ability to capture the hearts of girls in virtual dating sims. But in real life he’s known as 'Otamegane' and hates all '3D' girls, believing them inferior to girls of the game world. After unknowingly signing a contract from hell, Elsee, a devil from Hell who has heard of his legendary girl-capturing skills, comes into Keima's world and tells him about the contract he had made with hell, which is to capture the loose souls who escaped to earth. These spirits only hide in the crevices in women's hearts, and the only way to get them out is to make the host fall in love so that the gap in the heart will be filled. Keima unwillingly accepts the challenge, because if he doesn't, he will lose his head.
