Keystone

A young girl wakes up to find herself alone, in room of horrors. She doesn't know how she escapes, she doesn't know how she got there, she doesn't even really understand the world she wakes up in. So she seeks help from an unlikely place - a demon called the Wishmaster. Thrust into a strange and magical world, she meets Ciel, the Wishmaster. She makes a deal with the him - her memories for a price undecided, possibly her soul. All she knows of Ciel is that he belongs to the world of the Others, the world of fairy tale, fable and myth made real. If she trusts him she gets her memories back at a terrible cost. If she doesn't then she won't get her answers and won't remember who she is.
