>>44195239>>44195306I don't think that's relevant data. Out of curiosity I've tried to limit the search to Japan, and Hololive is almost a flat line, which even assuming they would still lose to Nijisanji, is completely unrealistic.
I think the difference might be in the fact that Nijisanji is treated as a topic while Hololive (and Vshojo) is considered a company.
