As far as Vtubers go she was not that huge. I'm guessing she was doing it mostly for fun and she had some money in her pocket and wanted to dip her toes in the corpo world. I feel like there is way more knowledge out there on how to run a corpo and how to not set your talents up for failure. Tsunderia, Phase, Kawaii, Prism and Cyberlive all feel like they get points for jumping early into the mix but at the same time there were a ton of unknowns on how to work things out. Hell even IdolHE felt like a bit of a prototype.
Now the market/audience seems to be better defined. There are a few things you can go for and it will guarantee that you will at least get baseline success. Maybe part of the reason she started Vtubing was as a way to understand the scene. Even half a year working at something gives you a different perspective on things. Her being female might also help her with dealing with her talents and their emotions.
