You are clearly disconnected from this whole trend and it shows. It isn't going away by just being a fad, these girls (and guys) are on their own, many times, proffesional entertainers (they get scouted and casted) the most popular ones do a shitton of entertainment content, it's non-stop; they are the full package, from singing to dancing, to gaming, to full otaku speeches on how much they love their manga/videogame/comic/movie/Gunpla/etc; they make the viral content. Take these out and they can still do their own thing, and here is the catch, the biggest one: all these agencies hiring a billion vtubers... collaborate with each other all the time, meaning you have crossovers of personalities all the fucking time. I'll give you a fucking grotesque example: picture Ninja streaming along Pewdiepie orwhoeverthefuckkidswatch every couple of days, the viewing numbers would multiply and break records every time. Once you get into an agency that clicks with you, you are set pretty much forever.
I'm totally in, I saw it as a fucking retarded thing before, but... Lord, not only the girls are funny, or so nerdy I can't help but die to be their friends, they are truly beautiful human beings; a huge fucking contrast to the western women/thot attitude on twitch culture. It's... good content; they get letters of people telling them they saved them from deep depression so many times.
Of course there is also a raunchy side, and yeah man, I enjoy it as much. Don't send help lads, this hole? it was made for me.https://www.youtube.com/watch?v=KXGwAZ1dZVw
