It's a story that is trying to establish varying levels of world building... it is doing it okay enough(won't complain about that one), but the author is putting too much emphasis on it without establishing an actual plot of events to follow.
So, we have:
-People go to an academy to become magicians
-Monsters are hated (but some do have intelligence and emotions), as a result of that, there is a devision of conservatives and liberals on that front.
-Samurai girl is from a war that happened to explain why she wants an honorable death.
But... What is TRULY the plot hook, the main conflict? It seems like it is supposed to be the monster thing... But it is being very strange about it, since there is not a single reasonable conservative to provide benefits for people to not save monsters, so it is one-sided and pointless for other than battle... Oh, and the conservatives are fucking insane with horrifying magic that straight up say EVUL(abortion magic lady, looking at you)
