Okay maybe I was surprised with Aella being the teacher, it wasn't a bad thing but I don't see much difference for the future besides the MC provoking her at all times.
Thanks for the chapter
The MC is very weak, he should use Souei to almost kill the strong monsters and he would kill the monsters and raise his level very fast, he should already be on nv90 +.
The speech by the principal to Syrin and Ruby is kinda cringy. He was speaking to them as if they are the ones who wanted special privileges and treatment and he had to go above their heads to their parents for permission to treat them like normal students. It could be just me though.
