Sakie Satou

Sakie Satou serves as a math teacher at Shibasaki High School, while secretly belonging to the succubus lineage among demi-humans. Her body naturally emits pheromone-laced perspiration that involuntarily arouses those around her, compelling her to adopt a carefully managed lifestyle: she dresses in loose, modest athletic wear and deliberately takes the earliest morning train to minimize any unintended effect on male commuters. Beneath her reserved exterior lies a sincere and principled soul who has long struggled with the burden of her unique constitution. It is only upon meeting Mr. Takahashi—a colleague capable of engaging with her through pure reason and composure—that she gradually lowers her guard and finds herself developing genuine affection.
