User blog comment:Mangetsu20/The Best Fairy Tail Chapter This Arc...?! (FT - 488)/@comment-4930882-20160611130017

I honestly think, for Irene to take on Acnologia properly she's going to need something more than just "OMG look how much magic she can use!" I mean, you're facing off against a DRAGON that's been around for what, 400 years? Damon pointed out that the chapter titles are counting down to something (inb4 after One Universe is 'The END') but, and this is just my opinion, I feel like starting from the Third Seal, the chapter titles have become more and more relevant if that makes sense?

Add in the fact that even Zeref was slightly confused as to what Irene was doing (a couple chapters ago) I honestly believe Irene's magic is 1. Something new, so not an ancient magic but in fact something from the new era and 2. Related to the way the world works. We know she can control the magic in the Earth, change the weather to spring even though it was snowing for ages, and the chapter title is One Universe, what if she can change (for a moment) how the world works and that's how she fights Acnologia?
