>>58723476The only official answers so far from Cover (including 2 streams from A-chan, Xtwitter statements, talents confirmation, Regloss talking about themselves) is that they will be more group focused and will tackle some more diverse challenges compared to traditional branch. What that means, we have not yet seen.
As for the differences we can actually see so far:
>a branch channel that is relatively more active than other branches>Revealing Idol outfit before debut>Debut group song>"normal lore" compared to regular holos, and a setting (Choberiba) that can potentially be used for physical events in the future (only speculation)>Girls have some unique niches that is included in their official profile (manga, rakugo, fashion)That's all we know. Some anons speculate that since Kanade is Korean, the branch might be for non-JPs, but there's no proof so I'd take it with a grain of salt.
Hope this helps.
