1st possibility: I think that it possibly can be the former school nurse. Maybe Osoro was the leader of the delinquents before Ayano was even in this school, and maybe she fought with many students and the nurse always had to take care of her wounds and one day the nurse told her to stop fighting but Osoro was against it and they started a fight in which Osoro probably got hurt by a scalpel on her cheek but the nurse may have been hurt much worse and that's why the director suspended her and asked for a replacement nurse (which is now our rival) But the normal nurse is gone for vacation on the substitute nurse's week.
