Holy whores! Definitely one of the best pieces of MSMM fan-art yet. I wish I could make out everything in Homura's wings though. I can only see a barcode and Adolf Hitler.
I wonder why the artist decided to put those in there...
No, but Anne Frank was. Putting my speculah hat on, I'm guessing that Hitler would be the cause of Anne going the deep end and turning into a witch. In the old timeline anyway.
