If you liked the Black Blood Brothers anime, the Anime-Planet community thinks you'd like:
In feudal Japan, Kurou and his servant Benkei are fleeing from Kurou's elder brother, who has recently ascended to the throne. In a forest, they come across a house and a strange woman by the name of Kuromitsu, who agrees to harbor them under one condition: that they do not peer into the inner chambers. Soon, they are attacked by the Red Army; they are searching for Kuromitsu, whose blood holds immortality. Fatally wounded, Kurou drinks some of Kuromitsu's blood and gains immortality along with strange abilities; but shortly after, Kurou is seemingly decapitated and wakes up centuries later in a ruined city. In this twisted future the Red Army is omnipresent and still searching for Kuromitsu’s blood, while a rebel army seeks to keep them from acquiring it. With threats at every turn and fueled by his obsession, Kurou sets forth to find Kuromitsu and seek his revenge on the Red Army.
Both Kurozuka and Black Blood Brothers feature vampire protagonists with mysterious pasts and fantastic combat abilities. The best aspect of both shows are the bloody fast paced action sequences.
In terms of plot of setting both shows are very different but if you enjoy good old fashion action and violence then these are both good choices.
In the streets of Tokyo, the nightbreed walk as humans, preying on innocent lives and feasting on innocent blood. There is one man who would put a stop to this: Shido, the Night Walker, whose blood is made up of the very thing he aims to protect against: the nightbreed. Along with his co-worker Yayoi, a green fairy named Guni and a clever young secretary named Riho, Shido and his detective agency take cases that would be otherwise missed and forgotten, to seek out the nightbreed and send them from whence they came...
Vampires are what both of these anime are about and it is the focus on relationships, not only between vampires but also vampires and humans, that are the main focus of the story.
Ofcourse there is also lots of fun battles and humor thrown in so that if you like a mix of drama, action and laughs then these series are definately worth checking out.
