13: Come on, this is just not fair. Poor Ultear had only one real battle, where she was beaten by Gray. Her main magic is incredibly versatile, and she tops it out with different secondary magics, but her strength seems to be in support. Mira, on the other hand, is a very battle-oriented mage, who has only one enemy throughout the whole series she can't seem to beat: namely, Mashima himself, who loves to give her the worst possible battles. However, I believe at some point we have to hold him accountable for the hype: Mira was introduced as Erza's rival, and was repeatedly stated to be her equal, and I refuse to handle her anything less than that. Is she's even only equal to a gmg-time Erza (which is a fairly acceptabble assumption, even disregarding my previous, clearly delusional comment - I mean, okay, I know, going by the battles, she's clearly not equal to Erza, but let me be a fanboy this once, ok? thx.), then she should bag this fight easily.

TL;DR: I give my vote, my life, and my soul to the most beautiful bipolar dominatrix, Mira-chan.
