Puella Magi Madoka Magika - WB: Magical Girls Are No Longer Secret seems to be phrased as though it might be an AU, though I don't know enough to be sure - from a bit of Wiki-diving, it looks like it might describe the end state of the series? Please clarify.

I realized after I nominated this that I could have phrased it better - what I'm really interested in is an exploration of what happens post-canon following the "reality reset" in the final episode and extrapolating on what that world looks like from the tantalizing brief glimpse in the episode (where it is unclear if magical girls remain secret or not). I'm just not sure of a concise way to phrase that - definitely open to suggestions!
