|Kanji||佐藤 早紀絵（さとう さきえ）|
Sakie Satou is a Mathematics teacher who also happens to be a Succubus. Similar to her students, her Demi-human origin has several repercussions in her ability to fit, and perspective of fitting into normal life.
Being a succubus, her body produces an aphrodisiac pheromone. Much to her dismay, this effect inadvertently makes any male in her vicinity to lust over her. Unlike traditional depictions of succubi as highly confident and driven, Satou is timid and shy, taking precautions to minimize her contact with - and appeal to - men around her. She highly admires Takahashi Tetsuo for his self control despite the apparent effect of her aphrodisiac, to which most males, even her students, succumb.
Being a teacher, she constantly puts her students' well-being first and foremost. Kind, gentle, caring, and somewhat clumsy by nature, these qualities present the image of an ideal wife to most men, amplifying their attraction towards her and further increasing her self-consciousness.
