Saya Otonashi(音無 小夜Otonashi Saya) is a fictional character and the central protagonist of the Blood+ anime and manga series.
Saya Otonashi is the main protagonist and anti-heroine of the anime series, Blood+. She is the first born of the daughters of the Chiropteran Mummy. She is a pure blooded Chiropteran queen and Diva's older twin sister as well as Hagi's lover. After waking up from a coma, she spends a year as the adopted daughter of George Miyagusuku and adopted sister of Kai and Riku, before recovering her memory and serving under the U.S. military faction Red Shield as their 'secret weapon' to take down Chiropterans.
Saya Otonashi(音無 小夜Otonashi Saya) in Blood+ is very different from the Saya of Blood: The Last Vampire. She was "born" in 1833 from a cocoon like object taken from a mummy of a Chiropteran along with another cocoon containing her sister Diva. Whenever her and Diva's blood mix, the blood crystallizes and disintegrates. She can only remain awake for a few years (three to four, at most) before sleeping again for three decades.
