It is indeed common. The allure of the vampire, despite being the hunted, and the hunter's own humanity that allows for love to bloom creates a complex and interesting dynamic. This kind of relationship in these novels often explores themes of acceptance, sacrifice, and the power of love to overcome differences. It also provides a fresh take on the traditional vampire - human relationship, making the story more engaging and multi - faceted.

And D from 'The Vampire Hunter D' series, with his mysterious dhampir nature and his cool sword - fighting skills against vampires.
