What most of you eop, clipnog, threadreader trash don't know is that due to her condition, Sora has to perform 3D Live events only in her underwear so that she doesn't overheat. This, besides the fact that she insists on performing Lives actually live rather than prerecorded explains why so few are game to perform with Sora as it's become customary for them to strip off too whilst giving their A game - no mistakes, no autotune, no redos. A few holos aren't deterred and go along with it in solidarity.
This was hinted as one of the issues of the new studio's staff shortage: they NEED a small trained crew of all female staff for Sora & friends events but finding women that are into this kind of tech work is very difficult so the girls' managers have had to fumble their way about it after getting a crash course by the engineers. Recall her bday Live when she got the hoodie outfit and how scuffed the audio was? Yeah that's why.
