Hell has a soul leak and needs to be fixed fast; rumor goes that on Earth, there is a powerful god-like human that captures any girl that he can grasp. Lucky for Elsie de Lute; the clumsy demon girl assigned to capture the lost souls, the capture god has answered her message! On the other side of the story we have Keima Katsuragi, an unusual otaku boy that only sees beauty in 2-D female characters from games. Keima shut his heart at anything that is not a digital world and has a set reputation of being a dating game god. One day he receives a mysterious email with a message that to his eyes looked like a whole new challenge so he decides to accept the deal.

After the email, almost instantly a joyful demon girl appears in front of him only to find out they were both mistaken. Elsie intends to capture real girl’s hearts in order to free the lost souls that inhabit inside of these girls and Keima is absolutely not agreeing with this but; too late. If Keima doesn't complete Elsie’s request, the necklace that randomly appeared on his neck will explode! so he has to do the impossible to get Elsie what she wants and is forced to work with her in order to live!

Another cute and positive, devil-like character like Lala. Elsie, has come to earth looking for a teenage boy! But in this case, this demon girl doesn't know that Keima was just a regular boy with a LOT of knowledge in dating sims. But just like Rito, Keima is forcefully doing what this other worldly girl asks him to do. Pretty girls in abundance and they all somehow fall for the main character! Another one just like To LOVE-Ru to join the comedy harem train.
