Tenshi & Devil

Chloe, a total failure of a incubus, comes to the human world for the first time in search of his target. Unfortunately, he gets the coordinates wrong and ends up lost. Remembering his target's name and face, Chloe searches for him while working part-time to make ends meet.

At long last, Chlore finally finds him and boldly declares, "Please give me your essence!" His target is Tenshi Kuroe, a university student and writer whose name happens to be the same as Chloe's. Kuroe offers him a deal: if Chloe provides him with information about the demon world, he'll give him his essence as a reward.

Chloe ends up moving in with Kuroe, but despite being an incubus, even a simple kiss is almost more than he can handle...!?
