Isoshio

Isoshio (磯塩) is a teacher at Kirigaoka Girls' Academy. S/he once published a thesis on why cats can't use esper powers. First mentioned by Tsukuyomi Komoe to Yomikawa Aiho when mentioning an experiment biased on the thesis seemed to concur with it, though Aiho dismissed the whole notion believing the researchers wouldn't even know if the animal's ability manifested itself in the first place.
