Raika is literally every middle school children ever. Bet you guys dont remember your middle school years or were the raika lol. She's not even bad. She was rude but eh. If sensei didnt had problems she might have been scolded for disrespecting teacher but that's it. I've seen a lot and way worse children during my middle school years lmao.
I see hannigram at the end of the chapters. Me so happy.
