The homeroom teacher of the protagonist's class (D). She is originally indifferent to her class, doing almost nothing to help them in the battle between classes, and remains unmotivated for the most part.

~! She learns about Ayanokoji's past and superior abilities early on in the series, and under the guise of having received instructions from his father and threatens him to help her reach class-A if he wants to remain in the school.!~

~! In the conversation succeeding Ayanokoji's father's visit to the school, it is revealed that Sae had her own ambitions for reaching Class A, and her threats against Kiyotaka were bluffs.!~

~! She later reveals herself to have been a student of Advanced Nurturing Highschool herself, and regrets not being able to graduate from Class-A during her time.
In Year 2, Volume 5, she informs her class about her own experience with the Unanimous Class Vote Special Exam, advising them to look over the merits and demerits of each option. She later reveals to Ayanokoji, that this exam had been her reason for not having graduated from Class-A, as she was unable to vote to expel her lover in favor of her class receiving 100 points, which resulted in the gap between the classes widening. She regrets this incident until Ayanokoji advises her that even if she had voted in favor, their class would not have won, lifting her guilt. !~
