Why does everyone act like the girls will 100% lose if they fight despite them having been a real knight order for a long time and seemingly was not inferior in previous contests against another knight order.
If they are really that weak they should disband or something because what's the point of having knights that cannot fight.
Two reasons, one we haven't really seen any exploits from their division yet aside from the two main female leads beyond word of mouth, and the other is the douche's quite up-front in fact over the idea that he's not above using dirty and underhanded tricks, and like he mentioned, intentionally chose people who weren't skilled so they'd get KO'd, just so HE could be the fuckstick that pummels the shit out of them. There's no telling what else might have happened so MC pretty much wanted to nip it immediately with his demotion strategy to make him serve as the vanguard.
