The old Cutie Honey manga from 1973 (so two years after Shirou heya no futari) is quite something. Honey goes to an all-girls school in the mountains, where the separation from men has reportedly turned everyone crazy, which is to say lesbian. We aren't talking about the most positive representation here; Honey's teacher has a moustache and hairy legs and is hot for her while also being in a relationship with another teacher. The teacher in charge of discipline is a sexual sadist, and the delinquents, well, see pic related.
