Yeah, now that i think about it she is breaking them by taking what they love and care for the most. Turn the idol in a porn star, destroy the track girls legs, cut off the dick from the fuckboy, got the nerdy kid to turn on his mom (she even got arrested for attempted murder).
Btw ch 22.1 just came out today, and only the leader is left. But he turned the whole school against her by faking being assaulted. Anyway, it looks like this won't be a long manga. Like 30 ch at most i'd say, which is ok IMO.
