Butchered It's Not A Phase choreography during the concert, and the MV only released after she announced graduation, likely with quick work of a second artist. It was initially supposed to release in May, if not sooner.
Miscommunication led to Fauna and Mumei not having a MC part during the EN concert
I think it was way later after Gura's graduation, artist on Twitter released an animated commission that was likely supposed to be Fauna + Gura second scripted ASMR, and there is a precedent to management blocking specific ASMR (that's why a lot of that happens in members only, and why Fauna lost interest in ASMR for a while if some of her other scripts got rejected)
Her manager was a total fuck up that never really helped her with anything, and she might have had some problems with getting a replacement (especially when she doesn't speak Japanese)
Not unlikely that she had some projects that got killed before we learned about them
She might have disliked the direction of the company when it came to shilling merch, but that's just a speculation based on her not participating in any sponsorships and collaboration merch (like jackets, watches, dice and all the other stuff other members were selling) for a good year since these started becoming more commonplace; she rarely shilled other merch too, often only talking about it when prompted by chat
Probably some other stuff, but that's all I remember or can speculate right now
