>>60182341Like for Mori? Huge, she'd be basically guaranteed to get regular radio play from the song and it could easily snowball into even bigger things.
For Hololive and vtubing as a whole? Honestly, not that big, basically every Japanese person who follows J-Pop already knows about Hololive, and Ado doesn't really have that large of an international fanbase. But I guess some international weebs who dismissed Hololive's music could give them another chance.
