Kizuna AI (Decimated)
The eyes are just an issue with the shader, change to CubedShaders, set render as cutout then turn down the Alpha Cutoff as low as possible.
Also be wary, the eyes are set as dynamic bones as well, just be sure to exclude them from any dynamic bones you intend to put on the model.
Decimated the hell out of it to make it into VRChat, but hey. I have it now.
