Sena Kashiwazaki is a blonde-haired schoolmate who is described as "perfect in every way except for her personality."The daughter of the school's chairman, Sena shows a dislike of all things "ordinary". She is both attractive and academically successful, but her arrogance precludes her from making female friends, and she treats her male classmates as slaves.She enjoys playing video games particularly bishoujo (games where the main character tries to win over a girl) because they allow her to make female (if virtual) friendsalthough some of the games have embarrassing adult content. She does not get along with Yozora, who calls her "Meat" Although she originally joins the Neighbors Club to learn how to make friends, she develops feelings for Kodaka after he scolds her for inciting an incident during their trip to the swimming pool.When it is revealed that, fourteen years previously, her father arranged a marriage between her and Kodaka (his best friend's son) Sena confesses her feelings and proposes to Kodaka. In the anime, Sena is voiced by Kanae Itō in the Japanese dub, and by Jad Saxton in the English dub. In the live-action film, she is portrayed by Mio Otani.
