Fuyumi Kousaka

Fuyumi Kousaka is the mother of protagonist Akiho and the root cause of her daughter's deeply distorted sexual knowledge. Sharing the same expressionless face and overly earnest disposition as her daughter, Fuyumi has a habit of casually dropping shockingly explicit remarks or prying into intimate matters without batting an eye. She firmly advocates an 'elite education' approach for her daughter, treating sexual knowledge as a subject deserving utmost seriousness—a stance that consistently leaves the male lead utterly flustered and at a loss for words.
