I noticed that but since it’s the first episode I didn’t want to jump to conclusions. The other irl characters were also represented symbolically, so it’s probably either to communicate that the character is the one that matters in the scene and the actor is irrelevant, or could also just be a way to maintain the “illusion” so to speak. At the very least, I’m inclined to believe that if they understand this much about vtubers, they must have made a concious creative decision to represent her as the character irl. Whether or not that was a good decision remains to be seen.

Either way it still bothered me though.
