I'm pretty new to Nijisanji so I can't quite recognize who everyone in this piece is supposed to represent, or if they're animalizations, mascots, or fanbase mascots. I've tagged and annotated the ones I recognize, hopefully that'll help anyone who decides to try identifying the rest.

EDIT: Found a Twitter post that identifies most of them.

Thanks to this comment I was able to find all of them.
I identified the last 3 creatures on the top right corner and yes they're all from VirtuaReal.
Maybe I'm wrong though
