I feared this chapter would have E.N.D., but instead it had Ichiya. Undoubtedly the MVP of the arc right there: He defended the Raijinshuu from Wahl long enough to repel the first invasion, he saved the guild from Wahl's railgun, and now he's going to 1v1 Acnologia, and ****ing win. Jellal's magic is cool, I guess.

Acnologia can eat all Magic? It's a good thing that Etherious Demons like Natsu use Curses, not Magic. And even better for Acnologia, because Natsu's "I'm Human" moment should have prevented him ever going all END ever again. Ever.

The new lady with Ichiya is somewhat mysterious, and I hope her Identity is revealed in the next chapter, but by far the biggest theory about her I've seen is that she's Anna Heartfillia, and honestly I can't think of a better option. How she's alive is somewhat questionable, except no it's not, she literally invented Time Travel. If it is Anna, I expect she used the Eclipse Gate, possible at the same time as the other Dragon Slayers (Who I suppose she just abandoned in the woods one day)

So once more, the fate of the universe rests in the useless hands of Orga Nanagear, the only mage in existence who's magic should be able to directly damage Acnologia. As a God Slayer, his magic cannot be eaten by Dragon Slayers unless they are out of magic already. Since Zancrow is Dead and Chelia lost her magic, Orga is the last God Slayer, and therefore the last person with the magic it takes to defeat Acnologia. We're all ****ed.

Okay, for realsies this time. Magic (Meaning Ki Attacks or lasers or whatever) has been innefectual against Acnologia, but brute strength has worked. Makarov could hold him down temporarily on Tenrou, Igneel bit his arm off, and just now he was hit with Christina. All of these are examples of non-magical attacks effecting him, albeit not very much. I would imagine that this would allow Magically Enhanced Strength to work as well. If Wendy doesn't forget she can enchant Dragon Slaying Magic into inanimate objects, I would imagine that would allow basic weaponry to work on him.
