Imps are a real thing, usually bound by contracts created by the summoner. And on the surface, aside from their horns, they can take on all manner of shapes.
Grit, at least, is just silly. His contract was created by a wiccan priest so his main work was just involved in natural alignments. Once he broke free of his duties, he loved what he was capable of on the mortal plane too much to go back. With the form of a monkey, he can usually be spotted at various clubs since he can't be out during the day.
To get by, he works as freelance security for said clubs, paid by the shift, and every full moon, he recharges the amulets on his foot gloves so he can stay on the mortal plane. With his muscular physique and charm, very few idiots are keen to mess with him, and learn their place.
