I could see her joining XSET officially as a content creator, but looking at the reaction to her return stream and the fact that she already has merch, sponsorships, collabs, etcetc planned after like 3 days - I don't know what any of the other vtuber corpos could offer her. (keeping in mind her niche as a gamer - obviously Holo would be the ideal place if she wanted to go down the idol route)
