>>12029743I think it's a consequence of the idol branding. Sure a lot of fans are probably okay with the idols interacting with guys, but since they're branded as idols, there will be those who expect the traditional idol experience, and even if we assume they're a minority they usually tend to be the loudest.
>how the two branches have this giant wall between themIt's kind of sad to think that (from what i can tell at least, please correct me if i'm mistaken) Holostars seem to have more external collabs than internal collabs. Heck Aruran and Flare have both been part of the same company for years but he managed to collab twice with his new sister from Nijisanji that debuted a few months back before we even saw a Flare collab.
