The World God Only Knows

神のみぞ知るセカイ

Keima Katsuragi is a legendary dating-sim player known online as the Capturing God, with zero interest in real girls. When he answers a stray contract email, he is bound to Elsie, a cheerful demon from hell, and forced to hunt runaway spirits that hide inside girls' hearts. The only way to drive each spirit out is to make its host genuinely fall in love — so a boy who only understands fictional romance has to win over one real girl after another using the logic of his games.
