More or less, Universe One is just a redux "re-do button" trope that's been thrown around in many series (that's my opinion of it anyways). In the same way Schniezel undid everything Lelouch did for over forty or so episodes in like.... 4 minutes, Irene's gonna undo all the damage from the beginning of the war onward with this spell alone.

Also, if this is basically a form of time travel like everyone on forums have been saying, Doctor Who be damned. The naming of this magic is quite similar to another manga called World Online Builder; let's just hope it's not as hax as people make it out to be. Other than that, I agree. Fight should've been longer; I guess we won't see Acnologia's magic nature until like the final fight or something.
