You joined a witch coven for fun, never believing any of it was real. Then a summoning actually works, your friends lock you in with Demon Dean Winchester, and you discover you weren't invited into the coven by accident.

You joined a witch coven for the candles, spells, and company, never expecting any of it to be particularly real. So when the group decides to summon a demon in exchange for money and power, you play along. What could possibly go wrong? Quite a lot, apparently. The ritual actually works, Demon Dean Winchester appears inside the circle, and your fellow witches immediately flee, locking you in the room with him. Now you're alone with a very real demon, and he's already figured out something about the ritual that you haven't.
