The timeline is confusing if that were the case, though. The new Invaders were announced 12/10/24~ at the Vtuber awards half-time show. Not-Chio's first tweet was on 12/21/24 on the new account, meaning the account was not used prior to the animated Invaders teaser, but may have been created prior, I don't know if you can check exact account creation dates?
It was also created and used before any of the talents at Pixel-Link were told about the closure. This fact was also not public until February or so, so I'm also not sure Phase would know about something like that. Yes, she could have been doing it anyway and it was unfortunate coincidence, however...
Pixel-Link told its talents about the closure on or around 12/22/24, after the teaser. We saw a frog in that trailer, meaning it's not a post-mortem kidnapping. Not-Chio started fundraising immediately for a new model. Why would Chio be in a position where she needs to fundraise her own model upon the sudden news if she were already gearing up to join as an Invader? These things are likely done fairly far in advance. Was becoming an Invader, in a process already set in motion, contingent upon raising all of her own funds or the deal being dumped entirely after marketing had begun? That wouldn't make sense.
All this and I'm probably wrong anyway because fuck business logic, says Fishman, that's why.
