One of the family members who looks after Miyauchi Renge in the Non Non Biyori anime. She's usually seen with Renge. Rarely opens her eyes, unless for that odd moment. Also known to sleeptalk and randomly snooze on the job.
She's also the school's single teacher.
Side note: the anime does not show the other family members, but gives hints that the parents of both Renge and Kazuho work in the rice fields.
