Do the principal and his lackey exist just to make MC look good? What is even their end game? Honestly it just seems like the author beating a dead horse
A'ight, lemme field this one.
Basically, as mentioned, this is the entire thing. This is the schtick. You will see it to the very end. But the end game?
It's really simple: Conservative Mindset + Skill Elitism + Noble Elitism = WE CANNOT, UNDER ANY CIRCUMSTANCES, ADMIT TO
ANYONE THAT THIS CHILD HAS TALENT, EVEN WITH OVERWHELMING PROOF. WE MUST CRUSH THIS ABERRANCY, WHICH UNDERMINES THE UNDERPINNING OF OUR GREAT AND NOBLE SOCIETY!
They aren't the only ones making Leopin look good. The students, by and large, don't believe he's worth anything despite the evidence. He
must be cheating. He's
definitely trash. There will be others, providing the manga goes on long enough. But the schtick will remain the same. Well, potentially with one exception, but I'm not even sure whether they're going to adapt that particular part, or continue the schtick past the WNs (abrupt) ending. Won't be the first time that's happened, if it does.
It's by no means the only story with this kind of elitism leading to an expulsion, pleeeeenty of examples out there. It's just that this one stands out because the zamaa is constant and nigh unending, rather than "Eventually, these assholes will get theirs, and we can finally enjoy Harem/Budding Romance/Royal Road Shenanigans/Unresolved 'AND SUDDENLY DEMON KING' by itself..."
For many, it stands out in a bad way. I personally quite like it, but I understand everyone's got their tastes, and I wish them well in finding something they enjoy.
