Wrong End

Corpse Party is a game that consists of high school students playing with the Sachiko Ever After Charm and being transported to a haunted school. Some are hanged, some fall to their deaths and others are murdered by their own friends. The once game was soon put into an anime and because of that, a group of otaku's discover this. One dark night at school they decided to try the charm and are transported to Heavenly Host Elementary School. While being chased by ghosts, these ten students suffer from death, crying and are stalked by Sachiko herself. With a whole lot of knowledge about this game/anime/manga they think they can all make it out alive, but they're wrong.

Way, way wrong.
