Diabolik Lovers More, Blood

Often I just select an anime series totally at random to watch, without any idea at all what I`m getting myself into.

This is something that I find broadens my spectrum, but at times, that might turn out a bad choice, while I also discovered some hidden gems due to this method...

Unfortunatly, this 12 episode series that originally came from a visual novel on the playstation portable systems falls in the first category...  in two words: Stockholm Syndrome...

Plot (from MyAnimeList)

Yui Komori, still held captive by the Sakamaki brothers—pureblood vampires after her blood—experiences yet more bizarre twists to her life following her stay at their household. Though haunted by enigmatic dreams, Yui soon deciphers their meaning when caught in a car crash, which subsequently leads to meeting four new vampires: the Mukami brothers, Ruki, Azusa, Kou, and Yuuma, who themselves capture the bewildered girl.

Yui later awakens in the Mukami mansion, where the brothers reveal their plans for her: she is their "Eve," and her blood will find the "Adam" among them; together, they will have the power to rule the world. However, with the Sakamaki brothers hot on their heels, things might not go quite as smoothly as they had imagined.
  
What I liked about it

* Storywise nothing, it actually felt a bit creepy to me.  But it is well animated and has some very nice piano music in it

What I didn`t like about it

* As I said, it`s a very creepy series in a disturbing way.  The Stockholm Syndrome is one thing, but apart from that the vampire brothers are also a bunch of perverted a-holes that abuse Yui constantly and roughly (in a NON Hentai way you pervs!)
