Man you have no idea. Anime is crazy about vampires. Here take a look:
https://myanimelist.net/anime/genre/32/VampireThere's over 100 results, just fyi.
And there's even more manga about vampires:
https://myanimelist.net/manga/genre/32/VampireOver 300 results.
Moreover, they cover almost every conceivable genre: action, horror, comedy, romance, slice of life, I think there's probably even a sports vampire manga out there, probably.
If you want something gritty and violent then I suggest the following:
Hellsing Ultimate
Blood+
Vampire Hunter D
But really, there's no shortage of vampire shit, you could conceivably consume nothing but vampire-related anime and manga and have years-worth of stuff to read and watch.
