Anon-A-Miss: Not What You Think I Am

Just another fine day at CHS, when one single notification shocks everyone. The question arises- What does she want and why is she back?

To put it simply, Anon-A-Miss is back, but not for revenge. Everyone at CHS is terrified of the outcome, except they get a pleasant surprise indeed.

Yet no one is able to figure out who she is. Oh, and Sunset Shimmer and the CMC have no part in it whatsoever. None at all.
