The Confession Tapes - S01

Akemi Nakajima is a high school student with a natural gift for computer programming. One day, a new student named Yumiko Shirasagi joins his class. She gets the strange feeling she’s met Nakajima before but brushes it off. After school, Nakajima and a few classmates perform a ritual to summon a devil. Using his computer, he conjures the demon Loki on the screen while offering up a woman as a sacrifice. Yumiko happens to see everything unfold-but what will this mean for her?
