>>13263561she took a ton of time off a while ago, and clippers clipped her to keep her relevant. She came back to a huge audience of her old audience plus a bunch of newfags. She barely streamed for a while so it had the effect of when she did stream, it was sort of like an event akin to the viewership Ayame gets when she does stream and a lot of viewers tend to jump on to check her out live after an eternity. Shion just started to stream regularly instead and has been inclining because of that casualfag audience turning into dedicated viewership. At least that's my take on what's happened, but I know trying to understand trends in vtubing is futile and fickle.
