Tanizaki Yukari is the girls' English and homeroom teacher (class 3), but a teacher with very unconventional methods and a close relationship with the class. Her students are casual enough to call her by her first name: Yukari-sensei, and even use the very informal and intimate name and title of Yukari-chan. She can be moody and, like Tomo, is incredibly impulsive and has a tendency not to think things through. Yukari has a rivalry/friendship with Minamo and attempts to prove that she is the superior teacher.
