Kazue Sonokawa

Momoka Sonokawa's mother. Kazue is shown to like weird things such as charismatic people "with glimpses of madness," cute little girls "who seem to be hiding darkness within them," and clever creatures "hiding a sharp interior inside stuffed animal-like appearances."

She also owns and is capable of skillfully using a model gun, being one of the few people able to outplay her daughter, Momoka.
