>>22032415This is the only screenshot I could find that didn't look like a smile, but it was probably a between animation while speaking.
Her default expression is a smile in her old facerig setup, and in VTuber studio.
I don't know if she has other expressions and doesn't use them, or doesn't have them to begin with.
I wish I had the motivation to learn live2d animating to help with her rigging
