What you get is a creepy-to-sexy reverse vampire harem. It's not great but I think it does the things it does quiet well. I think, the group of viewers that might enjoy this show are slightly perverted girls/woman (17+), that don't take things to serious.
Story:
The whole show seemed to me like a visual novel game (I think there is also a game available but I am not sure what came first).
Through strange circumstances a naive girl comes into a house full of vampire boys, that harass her in a vampire way.
With 15 minutes The episodes are rather short. In each the main character Yui has contact with some of the vampire brothers while the story about the mystery why she is in the house slowly develops in the background and makes you suspicious what's going on.
Here and there it gets really very creepy and ridiculous, but for me that was quiet funny.
Character:
The series is really short and there are a lot of characters, so there is not much time for character development. But each vampire brother gets introduced and you will learn something about their different personalities.
The female lead Yui serves her purpose as naive good-hearted girl (crying "no. no" while running into the vampire boys and let them bite her), but it's hard to feel real sympathy towards her since her actions are rather stupid.
Art and Sound:
The art is nice, atmospheric and the characters look good. I think the sound was quiet average. The music wasn't my cup of tea. There is a dubbed version available that is ok too.
Enjoyment:
It's an anime where I am a little bit ashamed to admit it, but I enjoyed it. I think it is good for what it is. And really if you watch this series through there must have been something that appealed to you. No offence, but if people hate themselves afterwards my guess would be that they have some problems with there sexuality.
