Kaya Sendou

Оригінальне ім’я: 千堂伽耶

Erika and Iori's mother. Kaya is estimated to be 251 years old and above, but she looks like a child, which gives people the image that she's her children's younger sister instead. Erika looks almost identical to her mother, the only difference being Erika's more mature body and the fact that Kaya's eyes are constantly red, which every vampire has when they have their vampiric impulses.
