Well the novel could have taken 2 directions, a realist one or a fantasy one, it took the realism one were she was acting like a real bully victim and not like a super hero the same with Kagami a guy who saw bullying and did what he could (and they are both kids too), and I'm glad it did, that's why I love it so much, we already have a loooot of fantasy vns out there, even the nekoko's route was a bit too much.
But this again is a personal taste, I love all types of vns but I prefer slice of life+drama above everything.
