I haven't seen any in a few years now. Last time I saw a bunch of Ayu cosplayers was after the Ladies Night PV.
Since then I've seen photos of people dressed like Ayu in the Sparkle PV and the red dress from the Mirrorcle World PV, but nothing more recent than those.
It may delight you to know I'm planning an A Song for XX A museum cosplay for the near future lol
