She is not MC's mother, if she can not understand fellow student it is questionable how can they from relationship. Also MC did not got beaten to near death but actually won (well i didn't try losing so i can't say what happens then).why shouldn't she have reported the attack? for honor?
the fact that MC doesn't want it doesn't matter. better to throw dildos on the windows, that usually solves everything
The part about throwing dildos... i will just stay students in a game... just imagine if IRL students wouldn't need to worry about damages and could prank people at will... holy shit.
