Also the principal likely knows the teachers past seeing as he said something along the lines "make sure nothing get out especially about bullying" but I think it's worth to note that the father is fucked in the head seriously, he cheats, lies and fucks with people's lives DISGUSTING! Also that female teacher is probably gonna come back and side with aizawa and go against that girls father for lying to her
Not really, i think the part with the principal goes in the lines of how many schools in Japan would rather turn a blind eye to bullying rather than lose reputation.
I don't think the teacher(former victim) started the bullying seeing as that one girl hates her, but I think he turned a blind eye because her dad was still the same even after 20 yrs? And waited till she felt like him seeing as soon as she's wants revenge he decided to hand over evidence to fuck up the bullys life. Anyways cant wait for more
