Aizawa Kaho

The protagonist’s genuine younger sister by blood, attending a different academy.

Exceptional in intellect, looks, and athletic ability.

Fully aware of her own charm and popularity, she enjoys teasing and flustering the protagonist by seducing him playfully.

With a straightforward personality, she dislikes pretense and always speaks her mind clearly.

While she takes great pride in her femininity and meticulously maintains her appearance in public, she’s surprisingly laid-back and sloppy at home.

“If I can make you jealous, that alone makes me really happy, Oniisan.”
