User blog comment:SethHeartphilia/Whos stronger Erza or Mirajane/@comment-25152698-20150910231012

Is this really a question? Erza is Titania for a reason.

Sure, Mirajane has three separate transformations, but that doesn't take away from the fact that Erza has an endless array of armors and weapons. She's a former guild master for crying out loud! Mira was easily defeated by Azuma, when Erza defeated him at more than his very best. Erza is the third strongest Fairy in my opinion, behind only Laxus and Gildarts. Heck, they even mentioned Erza was a candidate for becoming a Wizard Saint.

What other support could you possibly need?
