There would have been a way around this. A very simple way even. The moment Acnologia's body is caught in Fairy Sphere, he could have been hit by a weakness which allowed the 7 DS to take him down. For example he could have lost his ability to eat magic, or just have massive stomch cramps for that matter. -_-

And instead of Erza knocking Acnologia out of the sky alone, that too could have been a team-effort...

But nope, it has to be about NATSU and ERZA!

So why did Mirajane even switch into Satan Soul again? Just to pose and then leave it to Erza?
