柏崎 星奈

The wealthy blonde daughter of the school's headteacher, Sena shows a dislike of all things "ordinary." She is both attractive and academically successful, but her resulting arrogance leads her to be disliked by her female peers. Their admiration eludes her, much as she desires it; she treats her male classmates only as servants to be used, although many of them would like to be her boyfriend. Nonetheless, she holds Kodaka to a higher standard. She enjoys playing video games, including dating sims and eroge, partially because they allow her to make female (if virtual) friends. Sena doesn't have any female friends because she is envied by other girls due to her good looks and popularity with the opposite sex.
