Saya Otonashi is the main protagonist of the series Blood+ and 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.
Saya has the rosy-cheeked appearance of an average high school girl of age 16 with a height of 5'2" and weighing 89 lbs. She is black-haired with different hairstyles throughout time and brown eyes. Back in the zoo, she used to have long hair falling down her waist with the bangs tied behind. She had a pixie haircut by the time of the Russian Revolution. In Okinawa, she likes to keep her bangs and hair again in a pixie cut. After Riku's death, her bangs are shown to have grown past her chin, making her hair resemble a bob cut. In the last episode, Kai trims her hair to resemble her Season 1 appearance. She looks very similar to Diva, though Saya is slightly tanner from being out in the sun and has a different hairstyle and eye color and she wears either pink, nude or rose colored lipstick daily. Her brown eyes change to glowing crimson whenever she feeds on blood, changes to chiropteran mode or senses the presence of Diva.
