Kagami Hiiragi

As Tsukasa’s older fraternal twin, this studious high achiever often serves as the group's sharp-tongued "tsukkomi." Though she is a disciplined former class president, her tsundere nature reveals a shy, sensitive side, especially regarding her frequent dieting struggles. While she shares a love for gaming and light novels with her friend Konata, she prefers scrolling shooters. Despite her occasional ego, she remains a devoted friend who frequently joins her classmates for lunch, even navigating difficult course changes just to stay close to them.
