Fan Casting Diva in Blood+

Diva (ディーヴァ, Dīva) is the main antagonist. She is the younger twin sister of Saya and the greatest sworn enemy of the Red Shield. Like Saya, Diva is a pure blooded Chiropteran queen born from the Chiropteran Mummy.Diva bore a great resemblance to Saya Otonashi, except that Diva has a fairer shade of her skin tone, striking blue eyes and has long hair. Through out the series, Diva had been essentially a child in both personality and actions with a psychopathic streak of selfishness, which led her to become the younger one of the two. Since they're twins Diva should be played by the same actress who plays Saya.
