I hope she doesn't receive death threats like the other Saine sister who left nearly a year ago.

Makes me wonder why she had to return back after several months.

I recall reading something recently where she mentioned she'd use the avatar during long streams. Like she uses contacts which aren't comfortable for the long streams she usually does, so having a live2d would be convenient.
