Description
Sakie Sato teaches mathematics while navigating life as a succubus, a demi-human whose potent aphrodisiac pheromones inadvertently arouse nearby males. This condition demands significant adaptations: she maintains a strict distance exceeding four feet from male students and colleagues, and obscures her appearance at work with a red tracksuit, glasses, and a long black ponytail. Her features exhibit increased allure when her hair is down and glasses are off. At home, she favors practical sleepwear like tank tops and boxers. Physically slender yet curvaceous with fair skin and purple eyes, her bust size occasionally causes practical issues like stuck zippers.

Estranged from her father due to her succubus nature, she found support from age fourteen with Ugaki, an officer specializing in demi-human affairs. He became a father figure and confidant, advising distance to avoid her pheromones' effects, making him an early male comfort. To manage her condition, she lives remotely without neighbors and commutes on the first and last trains daily, waking at 4:15 AM to limit home time. She periodically stays in a disused school security room to reduce commute exposure. She declined available government aid for succubi with her potent pheromone level to pursue normalcy through employment.

Timid and socially awkward, Sakie contrasts traditional confident succubus portrayals. She remains deeply self-conscious about whether romantic interest stems from genuine affection or solely her pheromones. Despite this, she demonstrates kindness and dedication as a teacher, prioritizing student well-being and forming close bonds with her demi-human students, sharing manga interests with Yuki Kusakabe. Her cautiousness extends to avoiding sleep near others, as unconsciousness could trigger erotic dreams in those nearby.

Her character development centers on her relationship with fellow teacher Tetsuo Takahashi. Initially believing him immune to her pheromones, she developed feelings due to his apparent resistance and respectful treatment. She later learned he experienced her effects but consciously suppressed his reactions to avoid discomforting her, deepening her emotional attachment. Their relationship progressed gradually: they began dating around chapter 80, became an official couple after their seventh date in chapter 68 of volume 10, and navigated physical challenges like hugs straining Tetsuo's self-control. The series concluded with an epilogue confirming their first sexual encounter and its aftermath, subtly implying her succubus nature became more pronounced following the loss of her virginity.
