Scarle says she won't be going anywhere and she has a lot of stuff she's working on, but given that her girlfailure moment spiralled out of control in the fanbase and Fulgur did his really strange move, while I'm currently optimistic about her circumstances Nijisanji still has plenty of chances to fuck up unrelated to her.
With this false alarm, I honestly think the chances of them shutting the fuck up and the status quo returning because the average vtuber fan has a really short memory is slightly higher than it used to be. But, again, I'm being really, really rainbow right now.
