Whelp, Saya is officially gone now. As I posted in the liveposting thread, she confirmed that it was her personal decision, there were no disagreements or drama that led to this, she holds Phase in high regards and thanks them numerous times for giving her a chance, and that Sakana even asked her to stay.
Sadly, it seems she definitely has regrets, mostly stemming from her being so shy and not collabing and interacting with the others even though she really wanted to. She says she genuinely does love her genmates and will definitely be keeping in touch with them. Also said that she will shill Phase until the day she dies (welcome to the Phasefags, Saya).
An interesting thing to note is that a few times throughout the stream, she says she's "taking a back seat". She won't be streaming anymore and probably won't be posting on her socials anymore, but she says she
may show up for collabs and covers at times. She also confirmed she still has a cover that she's been working on coming out in the future. So, that would be nice to see.
Personally, I didn't watch her much, but I did enjoy watching her from time to time when she wasn't just doing reactions to shitty zoomer memes. Absolutely no offense to her, but because of this, mainly brought on by her lack of streaming consistently, she was on the low end of the spectrum for talents leaving that would hit me the hardest. Still, as I'm a big Phasefag, it's a shame to see her leave. It felt like she fit in well with Gen 3. Shame that they've been going through a lot as a Gen, but their current three active members are strong enough to carry on, and hopefully Hina will eventually make her return.
Best wishes to your future endeavors Saya, and hope to see you pop in from time to time.
