So, she's the first one to properly graduate huh. Honestly not super surprising in hindsight, between her dislike of restrictions and the chinks. She might also have felt a little bit "othered" by the idol nature of Hololive in a "Am I really the only one who wants to do anything even a LITTLE bit out there?!" sort of way.
I personally have mixed feelings about it. On the one hand, I genuinely liked her as a content creator, and I liked the vicarious feeling of psuedo-jingoism in the 'battle' with the chinks. She genuinely put in effort and was by far the most proactive in making Hololive interact in a macro level (Asacoc, Meme Review, etc).
Having said that, in my personal opinion, I'm not super sad to see her go, chief reason being her mental health. I know her type; if she's at the point where she's literally crying on stream, with THAT kind of personality, then shit has gotten waaaaaay too far. Humans are generally not programmed to accept constant criticism, public figure or not, and constant hate even less so. It wears on the mind.
Also, less pertinently, her content philosophy and direction constantly and visibly clashed with Hololive's. Not saying it's worse or better, but different and in many ways mutually exclusive. Hololive's collaborative nature being their selling point, this sort of culture divide probably contributed to her struggles.
People are saying she should open her own studio and pick up talents and I honestly hope she does this and poaches talents like Mori, Ollie, Risu and the others who are more in-line with her approach to vtubing. I'd certainly watch it.
I guess this also explains a lot come to think of it. Lifting the collab bans, the sheer AMOUNT of collabs.
Coco, it's been real, and you were a real one.
