Question: Are Vtubers also somewhat rising among non-japanese speaking creators? Like, do e.g. native english speakers come up with VT personas as well, successfully? If so, are they all anime still? Or is it still mostly a Japanese thing among some Japanese publishing companies and private vtubers?
well, Hololive (Japanese vtuber company) have an English branch. Outside that there is also plenty of English vtuber already. Nyanners, Melody, Iromouse to name the few and they are pretty successful.
Vtuber is here to stay, it provide alternative to those who don't want to show they real face
