Satou, Sakie

佐藤早紀絵

A succubus employed as a mathematics teacher. She must constantly take precautions to avoid inadvertently seducing her male students by making herself appear dull. She wears a tracksuit and avoids makeup, but if someone touches her, they become aroused, which causes her to avoid physical contact. When she accidentally touches Tetsuo, he pretends not to be affected so as not to make her feel uncomfortable, which ends up causing her to develop a crush on Tetsuo.
