Another theme might be identity. Since she is a vampiress, she may struggle with her identity in a world that may not fully accept her. There could also be themes of love and loyalty, especially if she forms relationships with other characters in the story. In addition, the setting of the story, perhaps a modern or fantasy world, may bring up themes related to the clash or co - existence of different species or groups.
There is also 'A Certain Magical Index'. Although not strictly about vampires, it has a rich world of magic and different species. It has a complex plot and a lot of character development, much like what you might expect from a light novel in the vein of 'Seifuku no Vampiress Lord'. The world - building and the way different powers interact can be quite engaging.
I'd recommend 'One Piece'. It's a long-running series with an expansive world and diverse cast of characters. The plot is full of adventure and surprises.
