Looks like it's referencing the entrance of Mayohiga at the start of Stage 2 in PCB. The snowflakes make it obvious as well, along with the circles that summon fairies. Oh, and Chen's outfit also seems to be directly based on her appearance in it.
Really wished Cover had made her Mafia outfit official though. This one is still cool, but could have gone with something different if they wanted to give her neutral special guns. The bulkiness of a deagle-esque really doesn't suit her overall aesthetic, maybe something more classy like a revolver or a 1911.
Only thing pathetic is a person responding to ancient posts just to stir shit and then bumping themselves because they couldn't stand being ignored by everyone when no one took the bait to respond.
