>>5414987I'll give you a rather in-depth answer because you seem cool enough. They're Hololive V-tubers. Hololive is an agency of virtual anime girls (Real girls who stream with a webcam on and use a Live2D app to appear as models). These V-tubers are enormously popular and are easily all among the most watched streamer on the planet. Pekora for example is the 2nd most watched female streamer in the world behind Amouranth. About 85% of Hololive is Japanese with the other 15% being English and Indonesian. They primarily stream video games, sing, dance, hold concerts, voice act, do ASMR. They all stream in character and try their best to keep their real life identities a secret but that's almost impossible to do because of the Internet. The girl (Of which there are about 50) in the OP is named Shirogane Noel who people suspect is "Canan8181", a popular titty streamer.
This thread is mostly just talking about the real-life counterparts of these popular anime women.
