Ayakashi - Japanese Classic Horror - Episode 1

"The dark and brooding Ayakashi is composed of three horror stories: the narration of a young woman named Oiwa who was abandoned and betrayed by the one she truly loved, leading her to curse all who stood in her way; a story of two star-crossed lovers – a human and a forgotten god – and their struggle to have a future together; and the tale of an evil and malicious demon who is haunting and murdering a family for unknown purposes. Though different in animation style and tone, each story shares a similar theme: the darkness of the human heart." Source: http://www.anime-planet.com/anirec/1028.html
