Dance in the Vampire Bund, Gosick Recommendations
The young blond girl are similar in personality and in the way they talk.
Both feature a blonde female lead character who is initially arrogant towards the male protagonist but also are trapped physically and mentally by conditions set upon them (Victorique with her father and Mina with the three clans). The male protagonists end up being the ones the female leads cherish. On a side note, Mina and Victorique are voiced by the same seiyuu.
I just finished Dance in the Vampir Bund and thought of Gosick, because Mina(DTVB) seemed alot like Victorique(GS) The whole master/dog relationship (although not specified in Gosick, you can tell) is common in both. However if you are looking for similar plots then these are NOT similar at all, although they are both amazing and not very long animes, only the character personalities are the same, not the plots. But I found it very funny that Mina Tepes(DTVB) is the same voice acor as Victorique(GS)!!
The story is about a boy who try his best to protet the vampire queen, and so he finds out that he is a werewolf. Then he remember that when he was just a kid he asked the demons queen why is so sad and then the queen ask to be by her side for eternyty and to preotect her and make her happy, or he will die. He fight with many vampires, giant spiders and even werewolf, to protect si precious queen.
Both storyes are about a boy who try to protect his beloved girl.
