I'll have to concur. I looked into it myself, and I definitely hear the vocal similarities. For anyone who wants to do their own comparison, I found the perfect video for it. Just a heads up; the video is hosted on Bunkr, which is commonly used to host porn, especially Onlyfans leaks and the like, which I believe this video is, but the video in question
is not NSFW. Its just a recording of her talking in some kind of roleplay, sound only. I mean, she gets risque towards the end, so use headphones, but nothing too bad. You can listen to it
here and compare it with her work as Ember Amane, like her recent Palworld video.
