Hmmh you can tell that regloss girls worked really hard for these dances and most of them are absolute beginners. It's still the usual scuffed hololive dancing rather than full tryhard.
Seems like regloss was fully set up to be a KR idol group, ultra autist dancers/singers who cant stream for shit. Something nijisanji tried to do and also that one korean boyband vtuber or strawberry prince.
They set up the system for it and everything needed behind the scene. But somewhere along the line, hololive decided to say fuck it and recruit using hololive normal audition with streamers first physology. Instead of dancer first.
At least now with 3d its easier to tell dev_is from normal hololive because their outfit will entirely be different.
