Antikalpa

A Dai comes from a family that runs a prestigious orthodox temple, and his childhood sweetheart, Yu Fan, is desperate to locate her missing aunt. In an attempt to help, A Dai agrees to participate in a special ritual that his schoolmates believe can help them seek help from the gods to grant their desires; however, they are lured into praying to the evil forces. As his schoolmates die one after another, A Dai attempts to use his ability to exorcise evil and save his friends. Ultimately, he confronts a thoroughly demonized Yu Fan and fights to protect the neighborhood from evil forces.
