Feast of Amrita

A group of high school students witness a suicide when they see someone jump from the top of a building. Alarmed, they quickly rush to the scene, only to find themselves trapped inside. As they try to figure out how to escape, they start to feel like they're being watched and suspect that the space they're locked up in is not what it seems. A horror anime with echoes of Lovecraft and Junji Ito written, directed and animated all by one single person.
