ノノ＝フランシスカ＝フェアチャイルド

A diminutive genius student who skipped her grades to become a part-time teacher at Youjou Academy. The students call her "Nonochan-sensei" and are quite fond of her.

Despite being a teacher and trying to act mature, she still enjoys childish things like "Okosama" (children's dinner menu) meals. If she notices one of her students sneaking sweets into class, she starts drooling...her true immaturity comes out.

Has the protagonist help her when she's too short to reach things in high places.
