I don't think a vtuber with any following would ever use Ai since it's a big no-no in vtuding communities, but there is so many weird things about this picture. Like lumpy space princess's different eyes and Jake coming out of Nux's arm, but still being in the background. The writing on the mug also looks like the Ai text. Also Jake's arms are just weird. I saw this while looking through YouTube as a promotion and was expecting to see the comments say it's Ai, but nothing. Mostly everyone saying it looks cool.
