I've been digging through vampire anime for years and one title that always comes to mind when someone asks for a dark female vampire lead is 'Vampire Princess Miyu'. I love how it leans into atmospheric horror rather than high-octane action — the mood is brooding, the art is eerie in that 90s way, and Miyu herself is both tragic and chilling as she travels hunting otherworldly creatures. The series blends folklore, loneliness, and a sense of inevitability that really lingers after an episode ends.
If you want something more modern and political, 'Dance in the Vampire Bund' stars Mina Tepes, a commanding vampire queen with a complicated, sometimes ruthless streak. For a more action-driven, blood-soaked take where a female character becomes a darker force, look at 'Blood+' and 'Blood-C'—both feature young women at the center of brutal, tragic stories. And if you're into school drama with gothic romance, 'Vampire Knight' places a mysterious, conflicted young woman right in the middle of vampire-human tensions. Each of these shows handles the idea of a 'dark' vampire lead differently, so pick by mood: creepy and poetic, regal and political, or tragic and action-heavy. I usually start with 'Vampire Princess Miyu' if I want something haunting and slow-burning, and that choice still hits me in a good way.
