>>76215388As far as I'm concerned, Elira is kinda mainstream compared to the rest of her peers.
Pomu: cute girl that is into idols and Solid Snake
Finana: coomer girl that plays gacha games. mostly Hoyo games
Petra: in the background most of the time, helps support other talents by making assets for their streams and mixing for their covers
Rosemi: mysteriously tomboyish cute girl that also likes fighting games and plays a lot of FPS games
Selen: the brotuber with a more "male" sense of humor than most guys
If you compare Elira to the rest of the people she auditioned with, she's arguably the closest to a "typical anime watcher" which I equated with "mainstream". Feel free to call me a retard at this point if you still believe so, I've explained my point adequately enough.
