Well, for start, you could have texted me on Discord—the link is in my vrc profile, which I see you found

As for the avatar, there aren’t that many assets here; they’re pretty old, and I think they’ve probably been leaked somewhere by now.

Main:

• Base: Manuka
• Face Tracking: Triturbo
• Other assets: Dynamic Gesture and GoGo Loco (Self edited)

FBX:

• Hairs: [ けもけもかもかも！Hair ] - https://booth.pm/en/items/5071217
• Clothes Set 1 (Sweater and socks): [ 彼ニット✦マヌカ対応版✦ ] - https://booth.pm/en/items/5064571
• Clothes Set 2: (Shorts): [ Poeny For Manuka マヌカ専用 ] - https://booth.pm/en/items/5061752

The clothing doesn't fit quite right out of the box; you'll have to adjust the assets in Blender. I reworked the textures by myself, and I might have grabbed somethin' from the booth, but I can't find it anymore—I'm too lazy to look, it was way too long ago, and I didn't save the .psd files back then. The shaders are by Poiyomi; I did all the configuration myself, and every material on the avatar was rebuilt. And don’t forget about optimization: removing unnecessary polygons, deleting unused bones, etc. (Actually, you can find plenty of tools that automate this; you just need to learn how to use them properly.)
