For those that missed the news, the artist of the light novel that became #anime Guild Receptionist, Gaou, was exposed on a talkshow (at the end of June) for having inappropriate relations with a 14 year old.
His VTuber art daughter #YuukiSakuna was caught in the crossfire for just being his biggest client. She obviously wasn't involved much with Gaou beyond being a business partner for commisioning art, but the repeated use of her image in the expose stream and news/discussions about it obviously took a toll on her.
She had a relaxed streaming schedule to begin with, but totally stopped streaming after that came to light, and recently returned, abandoning all projects that directly involve him that she wasn't contractually obligated for (e.g. the Round 1 collab had to go on), and using an image from a different artist instead of her VTuber model for the stream.
She tried to joke about it, calling it a "city blown overnight", and saying that she'd go back to "pre-debut VTuber, model pending".
