This isn't really a clever plan and its the most likely explanation. She wants out. She's made it abundantly clear she wants out. Niji is effectively holding her career hostage, refusing to release her, but keeping her suspended, so she doesn't make any money. So, this is her way to force their hand. Doesn't require her to be smart, just manipulative and desperate.
Truthfully, with everything that's happened, her best bet is to get a lawyer involved and threaten Niji with a lawsuit. This suspension could count as workplace retaliation, which is straight up illegal, since its largely a response to her complaining about the sexual harassment. Not to mention that they didn't even investigate the initial complaint, which she could also sue them over. Even if NIji had the money to fight the case, that's bad PR they don't need right now. And no company wants to risk discovery. For a company like Niji, it would be devastating. She claims to have more receipts, including discord logs, messages to both staff and legal, and more to that recording of Aster, which, from the way she talks, is far more incriminating. Having all of that come out in a court case is not something that Niji wants. She probably has more than enough to simply force her way out of the contract at this point, or even argue that Niji's actions voided it. Considering how damning all of this is becoming, Niji will probably just let her walk in order to be done with it. The only thing is that if Twisty walks, Aster HAS to walk too, and probably at the same time. He's become too toxic to keep around, and the allegations against him are too damning to ignore anymore. If Twisty is terminated, Aster will have to be terminated at the same time, so that Niji doesn't look like their taking his side in the dispute. At this point, they can just fire him for cause, and be completely and legally in the clear.
