Hiyori Miyazaki (宮崎 ひより Miyazaki Hiyori) is the mother of Chisaki Miyazaki.
Hiyori is a beautiful young woman who looks like an older version of Chisaki Miyazaki, but Hiyori has thigh-length orange hair that is tied in a low ponytail with bangs swept to the left side and larger breasts.
Hiyori's personality is both mature and childish, two former as she taught things to Chisaki Miyazaki (Hiyori's daughter), the latter as she has no resistance on something cute, showing heart-shaped pupils every time she saw something cute, like Koyuzu Shigaraki and Miria Katsuragi.
Not much is known behind Hiyori's past. What is known is how she won her husband's heart by working hard (like exercise and nutritional eating) in enlarging her breasts and eventually gave birth to Chisaki Miyazaki. She raised Chisaki and taught to be careful around men since they can be "wolves".
Hiyori is a normal human.
Chisaki is Hiyori's daughter who was the one who told Chisaki how "men are all wolves" and that she shouldn't trust them so easily. However, she is supportive of Chisaki's attempts to attract Kogarashi Fuyuzora, because she trust Chisaki's judgment.
A Tanuki who is enamored by Chisaki's boobs and sometimes stays at the Miyazaki household. Hiyori is very attached to Koyuzu and loves to touch her ears and tail. Koyuzu loves fondling Hiyori's breasts, which Hiyori doesn't mind and actually enjoys.
A Yoko Girl who serves the Katsuragi family. Like with Koyuzu, Hiyori finds Miria adorable and wants to touch her ears.
- Hiyori's surname Miyazaki means "temple, shrine, palace" (宮) (miya) and "cape, peninsula" (崎) (saki/zaki).
