I just spent some time finding the original avatar post of Puck online, and I found it, but the guy has disabled sharing. He only shares it on Twitter, according to google translate, and to those he deems worthy since he uses privateer or something. He also explicitly states he does not want the model used in VRchat, which is probably why he has made the model private. Well we know how that has happened already.

I know no one cares, but I didn't see these listed before and it was surprisingly easy to find if you just use google and Japanese. I'm still however trying to find the version that already has rigging done to it, or would you guys think it would be easier to use what I have (mesh, models, textures, some custom anims) and learn how to piece it together? Naturally I'd love to just have a ready made thing and go through CATS and edit it a little and BAM, but that isn't going to happen since I know no one who has the file and is sharing. I know one person and they are rarely online in VRchat.

In any case had to share. It's been a long day.
