Sayu reveals she's joining a company

She doesn't say which, but I'm happy for her in any case. She said in the past, that if she was to join a corpo, she'd join Phase-Connect, not VShojo. But she did also meet up with Matara at Offkai and talked things over with her, who knows. The counterpoint is of course that Phase-Connect has open auditions around now, and she's more than big enough to keep her current persona, something they only allow for quite established people.

Sayu did approach Kson about joining Vsj early on, but while Kson was sympathetic, said the some of the other members weren't sure about Sayu yet. This was still when she would tangent into venting about her old job and I think that might have been the issue. The other issue is that at the time, she didn't really have a strong connection to anyone at Vsj and viewers were just trying to meme it into existence. While I still think she would jive better with the other members of PhaseConnect, Vsj isn't completely out of the realm of possibility.
A month or so ago, Sakana revealed that PC is already in preliminary talks with three new Invaders. If Sayu is going to end up with PC, she would have been one of those three. I think PC has a few already locked in, but wants to round off the next wave with a few more and that's who auditions for new Invaders was opened. I'm not really a fan of Genshin Impact, but I do try and catch Hag Emblem or any other collab she's in.
Some people also suggested Idol, but they just debuted their "Encore" gen, so I doubt they're ready for another similar group so soon.

Remember to add click savers.

I don't know what those are.
- I'm not being entirely serious here, but a click saver is revealing what's behind the click bait so people don't have to click the bait.

The fact she didn't say it was VSJ, but that she keeps her IP makes me think it is a smaller company.
