立原 一音

Science teacher, as well as homeroom teacher for Yuu, Touka and Mana.
Since she just started her work as a techer, she still very much resembles a student.
That's why many students affectionately call her "Kazune-chan", although for Yuu, who as a class vice-president has often to cover up for her and deal with her immaturity, she's just a source of headaches.
Her family runs a Shinto shrine, so by all means she should become a miko, but she chose teaching instead, and burns with passion for it.
