Now this is just straight up plot hole and illogical, of this kid really brought and used a military grade armor, then the judges and referees would most definitely take his suit or disqualify him, the point of this competition is to mesaure your power, using any kind of external help, especially one like this is most problably against the rules, in a well written story at least, not in this one. If the author 1/1 copied black clover as it is anyways then at least he could've learned from it and not do this kind of bullshit, in black clover for ex. they enough brain cells to figure out that the point of an exam is to measure your skills and it would be highly contradictal if external help would be allowed.
