Well so Fairy Heart is like a Super Etherion weapon wow. Well Zeref was acting like a jerk this chapter, just tossing Mavis aside like a rag doll, but if he was more polite and handed Mavis over to Precht, he would kill him, so Zeref was doing him a favor.
So we learn more about Precht and hints of drove him to madness. I think his whole journey to finding the one magic was originally was to try to bring Mavis back, and at some point it just turned into an evil goal.
What I don't get if Alvarez wants to take down Acnologia, why don't they all just team up, we got a common enemy, this war is pointless. Perhaps if Makarov knew about this sooner, maybe he would have been able to strike a deal.
And we see how moved everyone is by Mavis' story, even Gajeel, and I loved everyone's reaction.
End of the chapter, Natsu ready to take on Zeref, looks like Zeref long time wish has finally come true. And we are going to learn what Natsu been hiding on his arm all this time finally.
Next chapter, Prelude To The Final Battle, Hiro keeps saying this is not the final arc, but his action makes it seems like this is the final arc.
Anyway great chapter.
