I have both some small news and very large news(credits to simpcity) so I will start off with the small news 1st.
Small News: Even though she was a NSFW VA for animations on rule 34 as aero_buddy the reason its small news is she is doing Rosedoodle kind of content on fansly.
Very Large News(credits to simpcity): Some vtubers on Youtube might fear Saba because attention would go to her 1st before that attention goes to them. Apparently the same might be said about Fansly. The power Saba holds on youtube as a Vtuber, this absolute semen demon vtuber might hold that kind of similiar power but on fansly instead. I think there is a good chance Bao, Nihmune, Cottontail, Trickywi, Vienna, Yuzu, Shylily might have some regrets dropping Sinder too early instead of using her as an ally because only she would be capable of combatting this semen demon by removing her own lewd level restrictions from stealing the vtuber coomer audience.

the last update it had was on June 24th, when the pfp was added, the account is still unverified. Think Saruei might be fucked to because 3d > 2d. Now of course this might still be too early to raise the red flag for a lot of twitch vtubers that coombait. Because we dont know if she will be super boring like rose doodle, boring like Sinder, or go beast mode like Mel and Bao on a late afternoon day stream. What we do know is that she loves 3d animations(especially overwatch kind) and has shown high interests in making her own voiced NSFW audios that go with them.
I dont think she would do hardcore streams like Mel or Bao but considering what she might charge, hot vtuber 3d model and voice it would still be a large threat to lewdtubers depending what traction she will get on grabbing a huge audience.
