Yuri's mother who also takes care of Shinobu due to his parents being on a long business trip. She treats Shinobu like her real son. Nazuna was Miru's former classmate and the two remain close friends even after graduation, and likes to tease her about how "she won't get a husband because of her flat chest". Nazuna is very kind towards her only child, Yuri, likes to give her counseling and teach her all she knows about sex and men to her. Because of her overall carefree attitude, she seems like a dumb parent, but in reality is quite competent.
