Wouldn't be surprised if he somehow overrode the principal's barrier by sheer brute strength and straight murdered hurt one or two of those other magicians/that one teacher.
@dope0420 totally he might create a nuclear strike with his fart. mushroom cloud and then there's the radiation(shit smell). oh boy just imagining it is already so terrifying.
At this rate, feels like the story is gonna progress without any kind of development to where he does learn magic, and it's just cast off to ignorance since he's so OP.
