Well quite a chapter. First of all the post Larcade stuff, glad that Kagura and Minerva got their closure, and maybe in the future they could team up, probably not in this arc, I think all of them are done for this arc. Sorano what kind of a dream are you having and about whom? Macbeth, Sawyer, Eric, or even Merody, you have some choices. Nice for Kagura to hope Erza doesn't die, but you know better get the heck out of here before Larcade gets back up. Now if only Minerva can bump into Millanna and she can really wipe the slate clean.
Erza vs Irene, yes that fight is going to look awesome in the anime. Irene is doing to Erza, but Acnologia did to her, and that is not take Erza's seriously and play around with her, you think Irene would know better. It is going to come around to bite her later.
So the confirmation that Irene is Erza's mother, and perhaps Erza hundreds of years ago like the 5 dragon slayers, Erza never took Freed's ruin test, so who knows. Irene queen of the dragons, you can interpret that in may different ways, Irene is a dragon or Erza's father is a dragon. Maybe Irene was a dragon slayer, I still want to know how she got that scar.
My theory Zeref told Irene to have a child as part of his plan, and have a dragon slayer spawn along with the 5 dragon slayers to go to the future and beat Acnologia.
Anyway great chapter, I am glad we finally got the Irene reveal, and also glad that Kagura and Minerva had that moment that I have long waited for.
