However, she was still labeled Essential, which is why you saw that message about the character's death and the prophecy. Rest assured, we are still moving forward just fine with the story of Hololive and Vtubers.
The real question is, who is the Yagrum Bagarn of Vtubing? The real, actual, axiomatically Essential character, whose death would mean the irreversible loss of both the Main Quest and the obscure Back Path?
