Billie Jay Cummingham (very much NOT her real name) is a demon from Hell that, most likely by choice, is abysmal at making people suffer or even fear her (for the right reasons at least). This is probably the biggest girlfailure of a demon in recent years since she is just full of love, joy, over-attachment, and a considerable amount of cutesy(?) insanity.And also lust...
Can't be a sinful being without a bunch of that!
In short, a possibly fun person that has very questionable, possibly nonexistent social intelligence and a lot of silly confidence when it comes to interacting with people.
Truth be told, if she was a mortal, she would probably get many, many restraining orders...
