Chieko Sannomiya

Chieko Sannomiya is the principal of the Seito Sannomiya Private School who was appointed office a decade prior to the story and carries herself in a conceited, yet formal and aristocratic manner. As a radical misandric, Chieko heavily supports feminism and, apparently irrationally, views males as barbaric. At the conclusion of the series, it is revealed that her sexism behavior was stemmed from a man who abandoned her in her younger years, who was the former gym teacher at the school.
