Jorougumo no Kotowari

Miyuki, an atheist, doesn't really believe in the idea of curses, even though she has a schoolmate, Yuko, who has supposedly used this method to have someone killed. Nevertheless, she supports Sayako in carrying out the ritual, in the hopes that it will give her some peace. However, after they speak with Yuko, they must face the fact that the curse may be dangerously real, and may carry with it horrific consequences. Miyuki's world is quickly spiraling into a nightmare!
