The Secret of the Raven

High school student Siho Kadono goes to a holiday in a mysterious village to her uncle, hoping to unravel the secrets of her family. As soon as she arrives, the fog thickens around her and she hears frightening words: "Get... out of here." But the girl does not listen.
The festive celebration turns into a horrifying sacrifice, and terrible creatures take Siho away. Now she is destined to play a key role — to care for a real deity on a sacred mountain, just as the priestesses miko once did. However, the evil and grotesque deity is capable of devouring anyone who does not submit to its whims. Siho learns to live among the cruel monkeys and ravens that have taken on human forms, and more than anything in the world, she dreams of returning home. Having learned the story of the god, she must decide whether to abandon the inhabitants of the sacred mountain to their fate or stay to help the deity find itself.
