Ibu Chiyoko

A teacher at Clearworld Narahama's very own Narahama High School.

For Mito and the others, she acts as their homeroom teacher.
With a beautiful body that any man would look twice at, she upholds a remarkably strict demeanor.

Her sincerity in this regard is so elevated that she seeks to orderly tie down her surroundings with her own style of common sense, to the point anyone addressing her with even the slightest amount of insincerity has no choice but to turn tail and bolt.
