This is one thing that Nijisanji is currently doing that's tasteful, debuting males and females together. If I wanted to be a vtuber I wouldn't want to be in some gay boys club where I was forced to collab with, draw, sing songs with, and reference other dudes all the time. The segregation shit Japan does is so gay. It's what leads to all the schizo unicorns and fujoshi. There should be options for people that don't want to be forced to interact with one gender.
