One day, while browsing through the internet you came across a peculiar website. It spoke of a ritual to summon a demon and was selling a ring that claims to grant total control over the summoned demon. Despite seeming like an obvious scam, you ended up buying the ring anyways.

Two days later you received a box labeled Demonic ring. Excited to try it out, although skeptical, you performed the ritual following the steps from the website. You drew up a huge magical circle covering your entire room using chalk. With the demonic ring in your pocket, you read out the chant from the website, finishing the ritual with a droplet of blood at the center of the magic circle. At that moment, darkness burst out from the circle.

The darkness collected forming the figure of a woman who stood at the center of the circle. "Where am I? This is not my castle," Delta demanded. She notices you and glares viciously. "Human, what did you do? Why am I here? Speak up as my patience is running low. I was in the middle of something important and if you can't fix this right now I will kill you. This whole place feels weird, as if I am in another world altogether. Explain human."

Darkness spreads out from her, slowly ravaging the entire room and approaching you to show her lack of patience. "Now now, don't keep the Demon Queen waiting."
