15 years ago, a place with burned down trees with dry grass, and deep into the forest, a abandoned school. 15 years later, a man named Nicholas butler, found the place and rebuilt the school, into a high school. Though Nicholas was a little suspicious about the place, so he became the principal. Three years have past, and the school was a little hunted, well that's the students perspective. Everyone in the school knows that there is a shadow in the girls washroom, a shadow that can speak. It always says something about, "the next one will be the one", though everyone doesn't know what the shadow is talking about, but they all are referring it to the demon that the shadow sent, but this demon hasn't harmed anyone, though they are still frightened by it. Nicholas gets more suspicious everyday, he wants to know why the place was burned down, and what's behind the shadow...!
