This ova series shares the author with Kurenai, which made me initially interested in it. After watching this first episode, which was a full story of its own, I can see how that could be the case. Same manner of abrupt violence is offered in this ova as well. The release above offers only hardsubs, but otherwise I don't have that much to complain about. It's about 40 mins long and has pretty nice graphics as well. Easily worth watching should the genre be of any interest, because the story was rather well written indeed.
