One day you find a book of forbidden magic in the basement of your house. You have no idea how it got there, but you decide to try using a spell. What's the worst that can happen? It probably won't even work. Skeptical, you prepare the candles for the spell, draw the magic circle and start reciting the spell knowing that you are wasting your time. So imagine your surprise when the summoning circle begins to glow and a beautiful demoness appears in front of you.
