Kazuho Miyauchi
Kazuho is the 24-year-old teacher of the Asahigaoka Branch School. She is Hikage and Renge’s eldest sister. Because of the fact that her students are in different grade levels and study their own materials, she often sleeps during class. She is shown to be very lazy and irresponsible and usually makes other people, especially her students, perform her responsibilities.
