I didn't watch Aqua much, but she always got along well with those that I did (e.g. Pekora), so it sucks to see her go. The strength of a Vtuber company/corp is in its people's bonds - indies may have more freedom, but they can't easily find other talented comedians or entertainers to regularly collab with.
These bonds forged can't be easily broken, but neither can they be easily forged... and one wonders where Aqua will go after this.
