>>37931943She is in fact EN, and would likely leave if the rest of her Gen is gone. Hasn't happen yet, but when more than half of a Hololive unit grads, the rest will likely just follow along.
Also cut the "biggest Vtuber" in the world shit, she doesn't even get the most Supers in her Gen, nor get the most views, or have the video with the largest amount of views in Hololive, or in her Gen for that matter. She as of this moment has the least interactions with the JP members out of all of Myth to boot.
