Sakie Sato

Sakie Satou is a main character in Demi-chan wa Kataritai.

She 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 a normal life.

Appearance
Sakie is an attractive young woman with black hair, purple eyes, and a large bust. She is most frequently seen wearing a red track suit and glasses; the tracksuit is to obscure her figure. When her glasses are off and her hair is down, Saki (according to Tetsu) has increased sex appeal.

Personality
Being a succubus, her body produces an aphrodisiac pheromone. Much to her dismay, this effect inadvertently makes any male in her vicinity 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.

Tetsuo Takahashi
Because he resists her aphrodisiac effect and treats her like a normal person, Saki develops feelings for Tetsu.

Trivia

 * She lives in a house in a remote location, as having neighbors would make her uneasy due her aphrodisiac effect.
 * Saki awakes at 4:15 every morning.
 * She is home less than she wishes as she is forced to take the last and first trains to avoid large crowds.
