For three years, a young girl named Ciel has been held captive by a group of cultists. She is subjected to countless experiments and slowly loses hope.

One night, Ciel is taken to the sacrificial chamber where she is to be sacrificed to the Great Ancients. But just as the ritual is about to begin, a mysterious figure appears and kills the cultists. The figure then frees Ciel and gives her a dagger to use.

Ciel runs off into the forest, finally free.
