DISCLAIMER!: I'm currently enjoying the Manga, actually it's one of my favourites and I'm planning to finish it, but I just couldn't hold it in any longer lol
Ok, it's not even funny anymore, I'm sick of these cowards. Everyone just blindly attacking Kitano and causing him serious injuries without even trying the "Talk " option, I don't know if this is the common way of dealing with "delinquents" (since I was the peaceful kid who avoids any kind of problems and just went home straight after school so I don't have much experience with deliquants and such) but I don't think a teacher can just attack a student like that.
