Quiet girl in the same class as Kohei, she is often seen alone and is near failing all of her classes except for Maths.
Kuze Kiriha is described in the Anime as a very beautiful girl. She's very good at math and achieved #1 ranking in her school and class, however, she failed nearly every other subject. Kuze is not the same as Erika, she's a vampire servant, which means she doesn't t need blood for survival and still has superhuman power. Her master is Erika's and Iori's mother, Kaya. In the episode, where she was busy looking for her master, she and Kaya then meet when Sei Togi brought Kuze to her master. The reason Kuze doesn't remember her master is because Kaya erased her memory which when they met she slapped her. Kaya treats Kuze as a game, or even as a pet, referred as she likes the "tag game" she has with Kuze. Kuze can be described as emotionless, quiet, aloof, smart, and calm. She isn't interested in sports or clubs, but thanks to Hasekura Kohei she can enjoy the sport festival a little bit. She has lost her sense of taste (in the anime, she ate a lot of chili, but doesn't feel a thing).
Kuze is voiced by Erika Narumi.
