My Predictions are
Froot: Gets hit with the final yab through either her or her mother's stupidity and graduates from content creation joe cat style (long shot).
Naynners: has been in a downward spiral for a while and will just quit vtubing to focus on flesh streams and other content as its clear shes at the end of the rope.
Gura: retires as it is clear she doesn't want to do this anymore.
Yuko: Seems like there is a lot of rumbling behind the scenes, and Idol may detonate if they can't right the ship, and the first sign of their collapse would be her leaving to save her own skin. if this happens, there's a good chance most of the other girls follow through; that's still an incredibly remote possibility now
Most of the EN Nij talents: Kind of a cop-out, but Selen shit show is looking Final Yab tier, especially if it comes out that she tried to kill herself; there's a good chance most of them jump ship. Like, what's happening to Nij ID, so it's a real grab bag of talents leaving..
Muyu: I honestly think most of the phase girls are in a good place right now, including Muyu, but given just how dog shit her life has been going as of late, phase is all she has. So, while this is the most unlikely prediction on this list, she would only graduate by killing herself. I hope to be wrong on this and that she gets the help she desperately needs from the other girls, but the possibility of her killing herself remains.
