User blog comment:Besteverunited/What do you all think will happen in chapter 476 Bid Farewell to the Magical Girl?/@comment-27900536-20160302031921

Truthfully, I think one of two things will happen.

1. Only Wendy loses her powers, (after unleashing some secret dragon slayer art) thus preventing Acnologia from killing her.

2. Both mages lose their powers however, Porlyusica does something later on to restore their powers.

I strongly believe in my first thought.
