Where the Demon Watches

Six women each have an evil plot up her sleeve, and soon enough, Zinnia is involved, informed also that it involves a demon, of sorts.
When she's seemingly rescued by a handsome, darkly princely brooding artist name Fredrick from a long series of depression and a grave mistake, she vows to help free him from whatever hell these witches put him though, and possibly slay the demon. If she succeeds, then maybe she'll be free, too. However as she's dragged further into this odd series of games, Fredrick insists that this demon had become omnipresent... and is now screwing with them all.
A lesson to be learned, though, is that while people can be immensely difficult to truly trust, they are just as easy to shatter. At least for a few rounds.
