I might skip on this one.
I've read too many Web Novel and I've develop this habit on avoiding series that only have fantasy/isekai + school setting. Their core plot is all the same to one and another.
These students character are pretty fucking annoying to read. Their ego high as fuck without knowing the outside world, and then the OP MC comes into the school smash those idiots into million of pieces.
Oh? MC is an impotent cuck and was bullied in school? well fuck, now he get an OP boost out of nowhere and rekt those trash for revenge so the author can fulfill their self-esteem which he/she couldn't do back in the high school. Also yes, since it is a school settings there are tons of female student for harem candidates ain't it. The heroines are fine, they are cute why the hell not... even if they are hollow. At least it is pleasing to my eye.
