Orrrr, she'll take the money and a portion of her fans and go back to her previous occupation. The key difference here is that Kiara always wanted to be an idol, but for Mori it was a means to an end, that end being her rap career and hanging out with e-celebs, which she does now and doesn't really need Hololive for anymore.
Ask yourself this. If it came down to a choice between collabing with e-celebs and staying in Hololive, which do you think she'd choose? That's the different between her and Kiara.
