Name: Nagisa Kyogoku Age: 17 Height: 168cm

A lady from a prestigious family. An honor student excelling in academics and sports, her graceful gestures make her the idol of the school. She shows little facial expression by design, but when her guard is down, she shows age-appropriate reactions. She is self-aware of her persona as a detached, cool character and matches her behavior to it, but never admits to it herself to maintain the aura. She smells incredibly good. She has no boyfriend or fiancé.

After accidentally saying something lewd in class, she couldn't show shame due to her cool persona. Her attempt to fix the situation led her to adopt a "dirty talk" character instead.

She isn't the type to be bubbly or social. Even after she started using lewd language, her close friends haven't changed, but she's troubled by the fact that distant acquaintances are avoiding her. It's not that she likes dirty jokes; she won't bring them up unless prompted. When she does speak lewdly, she does so matter-of-factly without a hint of a blush. She shows blatant disgust when targeted with sexually harassing comments.
