There was actually 13 episodes available out there. it is a great anime to watch if you don't mind a bit of ecchi and a little bit of horror. The horror element in this anime is a bit low so i wonder why they would put the genre horror in it.
The OP song and the ending song was superb to those who like to keep anime songs as collection btw!
originally i thought this is going to be a very gory/ horror anime but it turned out to be a rather comedy/ romance anime instead. its a pretty good one that not many people know about, worth a watch if you don't have much to do and a die hard anime fan, made me cry at the end ;)
