Sena Kashiwazaki

Sena is the daughter of a prominent school principal, which places her in a privileged position and contributes to her superficial popularity. Despite being surrounded by admirers, she never manages to form genuine friendships, as the girls reject her out of jealousy and the boys only see her as an object of desire. Due to her loneliness, she ends up joining the "Neighbors' Club," a group made up of students with social difficulties. There she meets other characters with similar problems, especially her constant rival, Yozora.
