Not going to lie, I'm surprised that this is ending like it is. I mean... the premise lets them basically keep doing whatever they want and they have gone to some ridiculous situations already. But I suppose every story has to end somehow, but I would have imagined it would be with the girl graduating or something, not just entering a new term and having a new monstrosity that scares even the biggest monster in class show up only to get classically shut down instantly like any other chapter.
