she might be more interested in jp vtubers outside of holo, she was basically part of the foundation of the EN side of things when she was part of eilene crew. The resident moe poster could chime in with better info but after the falling out with eilene she fucked off to a corner on twitch and just streamed to a small audience and with her friends. She'd probably fit in more in niji to be honest but maybe she saw how ame does and thought she can ride the wave the same way. The girl can't sing for shit and her third stream was a karaoke
I don't think she's that retarded to not know what's expected of her, the question is if she has what it takes to deliver.
