Yeah, Miyu is a very crappy friend, she's probably never had a friend before I can understand her behavior, but still, I don't like bad friends. I look forward to seeing Berserker or someone beat some humility and appreciation for other people into her. There doesn't seem to be any mature force in the show that could guide both wayward magical girls towards strengthening the respective weaknesses in their characters so they're going to have to learn to get along since they cover each others flaws so well.
