Azuma Haruka♀

She is the next head of the Azuma family and the eldest of four sisters. She is the head of St. Orkis Academy. She is a strong meritocrat, and does not recognize the value of existence in those who cannot produce results. She is also an excellent student and believes that if she can do it, others should be able to do it too. Her leadership is so severe that she sometimes uses corporal punishment, but no one can stop her. She is the reigning queen of the school.
