Hmm... If Artoria and everything she ever did was deleted (everyone's reversing the transfromations), wouldn't that mean Ira and Victoire would still be in Hildr's clutches?

No. If anyone ever played Nier, the first one not Automata, and got to Ending D, they'd have an idea how this works.


But to summize, when someone is that thoroughly erased from existence, their actions are ascribed to others in their collective memories. So in this instance, people would recall it as Ira or Victoire being responsible for this escape.
