Thanks again to Yonkou for the early release.

Very touching scene there between Erza & Wendy.

Guess we have to wait a little while longer to see what will actually happen to Natsu.

As for the strongest wizard, could they be talking about August? I think one of the earlier chapters mentioned he was stronger than Zeref. It could also be Acnlogia, haven't seen him around for a long time now.
