The premise is simple, harry potter with swords and magic swords. Everything is cool and all but the story is kinda not good. Personally, the most important in a new fantasy world is the world building. You don't need much but you need at least enough to make some sense. If everyone is an asshole in a magic world it makes sense, you got those power and you can do anything you like, but at the same time lawless too? Did the author forgot that the setting is in a school? What are the teachers doing if seniors are given the free reign to hunt students without any consequences? Isn't the point of school is to create an environment of nurture to atleast let the students protect themself? If the student is already expected to be able to defent themself before they were taught anything, then what's the point of the school? As a battlefield to hone killing instict? Does nobody cares about the mortality rate, because it seems normal students not part of the MC clique will just die as easily as those without magics.
Secondly, regarding teaching, is there no safety nets? Are students really expected to not f up every situations? Because currently, every class just seems like a ticking time bomb ready to explode. Is there no safe environment in the school? If any crjme is okay then why not just kill all problematic students? That seems like a simple solution to all of your problem, why bother warning?
Thirdly, regarding discrimination against magical beast. It doesn't feel real, it felt like the discrimination is only there to make the girl ( you know which one ) looks better. "We eat those magical beasts in the past!" Seems like just an assholish things to say considering you could still done those things right now, if it's banned that's even worse. It's like being a nazi after nazi is banned, or proudly proclaiming you used opium after the government has banned its usage.
The pacing is also kinda bad, i don't know if it's a manga only problem or both, but imagine harry potter is implied capable of using avada kedavra not even halfway through the book. At least start the plot after you introduce the character properly. Everyone looks straight out of a template, cool and edgy MC, pure girl, a friend A, kinda ass glasses guy who turned out to be not kinda ass later, good girl gyaru, battle crazy japanese.
