Supernatural, Modern Fantasy, slice of life
The supernatural isn't so uncommon as angels, demons, and everything in between have shown to be real. There has been much indifference at first; however, as the years went on, laws and treaties have come together so all races can live in harmony. Its been over thirty years since this has happened, and most have accepted the day to day life of seeing all manners of creatures; heck they even live in the same neighborhoods, apartment complexes, and even marry humans. There is still the struggle of some who can't adapt, and because of this, they've taken to living in solitude and using their innate abilities in secret.
In an unknown complex, there is a rumor about an incubus who spends his time sleeping with a woman who he finds attractive. Still, when someone comes to investigate, or the landlord comes to deal with the disturbance only the roommate is around and says he's been trying to make him cooperate with the demands. There have been various other corrective officers who have come to deal with this, and none have been able to get direct contact with the Incubus in question. It seems as if they are so close, but far from the problem.
