Nijisanji EN is what happens when you hire hags who used to browse tumblr in 2008 and discord groomers to be the bulk of your streamers, the end result was predictable.
Each company has a culture that reflects who was hired into that company. Most of the girls in Nijien are slackers who probably furiously retweeted Obama when he was president, liking everything he said. Many of them are dropouts who feel entitled to success.
Production Kawaii is mostly normal, friendly girls with 6 figure day jobs as programmers, most of them have Master's degrees or have been to college and have day jobs and educationally mog the other companies.
Hololive EN is mostly 'actual' streamers, the kinds of girls who were min wagies and broke college students with loans whose first choice was to make it from being a streamer.
Phase Connect is full of the kinds of chicks who open a date by talking about how they were at the doctor to renew their xanax prescription because they're so fuckin quirky and crazy (ironically they also make fun of quirky girls).
Prism is full of girls who are always on hiatus since it's not serious to them.
Idol is full of women who served in the military.
Obviously there is sometimes overlap, culturally, since they are all hos aged 18-39 running in similar circles but the types of girls getting hired are influenced by the types of girls already working there.
