Damn, Izumi is a super bitch. First she steals the most likely highly valuable stone from Mirai, and now she takes away her license despite the fact Mirai is nearly literally starving from lack of money. And as if that wasn't enough, she even tells Mirai to be more careful [if she doesn't want things like this to happen again]. If she hadn't stolen the fricking stone, Mirai could probably afford a month or six no problem.
I don't care if Izumi is Mitsuki's (and Mr. Siscon's) older sister. Something bad needs to happen to her for the sake of justice. She's plain evil. Although more than that I'm annoyed by the meek attitude Mirai and Akihito have. If you have a power others fear, then let those others treat you normally like they would treat anybody else or have a taste of that power.
