"Vampire Princess Miyu is a four-episode OVA series that was originally released between 1988 and 1989. Created by Pony Canyon and AIC, it is based on the manga by Narumi Kakinouchi and Toshiki Hirano. Hirano also served as the director of the OVA series.
The story is told primarily from the perspective of Himiko Se, a spiritualist hired to perform exorcisms and similar practices. However, her job is fairly mundane, without many encounters with the truly supernatural until she takes on a job that has her cross paths with a mysterious girl named Miyu. In each of the first three episodes, Himiko and Miyu encounter demons called Shinma; beings from the dark realm that have invaded the human world and that seek to use and abuse humans for personal benefit. The fourth and final episode ties the series up with an exploration of Miyu’s past and origin, as well as some revelations regarding Himiko’s own past."
