>>7805448Fujoshi is a meme buzzword on this website that people use to describe all female otaku, but fujoshi are a very specific group of women who are interested specifically in fictional male/male relationships. They don't care if it's "official" or not, so any friendship between males is enough to set off their imaginations, as long as they aren't butt-ugly.
The majority of male vtubers have a majority male audience, so the female audience's importance when it comes to a male vtuber's popularity is vastly overestimated anyway. But they gachikoi like any lonely people do, so it's not like they should be ignored wholly either.
Basically just be entertaining and attractive and an audience will come to you.
