Damn this manga is riling up my emotion. If you don't want another war then STOP trying to get both sides to hate each other. Plus they're sisters so why tf are you trying to convince her that her dad who's been with her since she was young that he's a bad guy when all you brain dead cult and fairies did was kidnapping her family. If anything it'll make her hate your tadpole brain fuck even more
Holy fuck what an incompetent cult they didn't even try to do a background check or something to ascertain the capabilities of the man they're "rescuing" the hero from.
