User blog comment:SethHeartphilia/Whos stronger Erza or Mirajane/@comment-1153699-20150701011432/@comment-24943679-20150712001712

I feel like if Mirajane had more willingness to fight and had not lost her powers, she would be unbelievably OP. Her takeover is shown to have a lot of potential. If she takes over powerful curses or magics from demons, that would allow her to beat Erza. The two battle differently as well. Mirajane usually doesn't have advantages over her opponents, so she relies on raw power. Erza usually looks for weaknesses, and defeats them that way. lol or, since she is a main character, she might give the signature Fairy Tail friendship speech.
