I smell a case!!!

Jokes aside:

If this Vivi is from Anti-tower and considering these two images are from the Hildibrand Season 2 section of the 2.3 update. The Anti-tower is most likely part of the Hildibrand Season 2 storyline. This would hint into what Hildibrand season 2 may be about.
I don't think it would be the case. People complained how they were forced to do the Hildibrand quests in order to unlock the trial roulette (both Ultros and Gilgamesh part 2 battles are in there) and I think Square said they wouldn't do something like that again for 3.0.
