Saya Otonashi (音無小夜)
Background
Saya displays superhuman senses and strength, as well as cunning, resourcefulness, and skill. The manga series suggests she was a human-vampire hybrid. Her age is unknown, but a picture of her with nine other people is shown in the film with the date 1892 and the word "vampire" attached to it. Though she holds most humans in contempt, she seems to have some sort of respect for David.
