@Kajiki - Mnnnn yes and no. Depends on how Quadimension wanted to handle it and if SHN approves. :P

See, NetEase could have easily picked a professional actress/singer for Lorra, but didn't.  They allowed the fans to choose

Quadimension, despite being a group of producers (or fans, if you want to call them that) gets to decide how they want to choose their vp. And since they're recording in June, it's assumed they already picked who is voicing Stardust.
