I've mentioned this before, but I'm a Vtuber OG (I've been watching ever since Kizuna Ai, in fact), and had even watched Sora's original video from 2017 (though I may have been one of the Knights of the Round Table in that community I think. I could be wrong).
It was only then that I had rediscovered Hololive in 2020 during the Vtuber Boom, and was hooked on several Japanese (Mel, Choco, Marine for a bit, Akirose and Roboco to name a few). I did see a few clips from Nijisanji, but the management from AnyColor become corrupt, which is why I stuck with Hololive (and its extensions like Holostars, Uproar and Dev_IS). Now, Hololive is also corrupt, but it's not as bad as Niji (I also watch indie Vtubers and/or smaller agencies for that reason alone).
