Our Puppy (Fem Helluva Boss x Male Hellhound Reader)

Y/N was just your average hellhound. Or, that's what I would say if that was even remotely true. Y/N is one of the, if not THE most deadly killing machine in hell, and is even an considered to be an overlord in most places, and thus is treated like royalty by everyone. Apart from the imps at I.M.P.
(Immediate Murder Professionals). He doesn't like to be treated like a king all the time, so they're the only ones he can just be himself around. Plus, he also works for them as an assassin, and a highly skilled one at that. This, ladies and gentlemen, boys and girls of all ages
(as long as they're in, or past their teens), is where our story begins.
