Corpse Party

Kisaragi Academy student Mayu Suzumoto is transferring to a new high school, leaving behind a sizable group of friends and countless lovely memories. To help her cope with this move, her friend Ayumi has devised a seemingly innocent plan: the whole group will come together to perform a charm she found on the internet called "Sachiko Ever After", which is supposed to bind all of its participants together as friends to the end.
