Brand new factory sealed dvd is in the Japanese language with English subtitles. The cover is a little misleading, there is no demon, possession, monster, etc. it has a figurtive meaning. Out Of Print (OOP) and no longer being manufactured. 

Yuki once lived a peaceful life with her loving parents, but her family's happiness was taken away suddenly one day by a group wearing black cloaks. Her father lost his abilty to walk, and her mother was massacred. Yuki, the only one to escape the violence, was left with unanswered questions and profound sorrow.

But that sadness soon turned into a smoldering anger and a burning resolve to get to the bottom of the mystery. Fashioning herself into an elegant demon of vengeance, Yuki sets off wearing her jet-black Gothic Lolita dress (it's Victorian style) in search of payback for her mother's death.
