Why does this chapter in particular have this many weird translations and inconsistencies?
"It's certainly understandable that they find it hard to accept" who are they? He was talking to/about one guy specifically, or is he so detached from reality that he isn't even acknowledging humans talking and speaks about situations at large lol?
"Decided by principal at his own discretion" principal is a woman.
"opportunity to be convinced" - to convince, he is trying to convince them, not be convinced himself.
"Staking my pride as the top student, it's a duel!" this is a 'dangling modifier' mistake, mismatched subjects between parts of this sentence.
And more. Also, it's not related to this chapter, but Zero Mist was called dragon king previously, even though she's clearly a dragon queen.
