>>61431005It's because Niji doesn't support new debuts.
Look at Advent and ReGloss's debuts, the majority of Cover put a pause on their activities and made the debuts a big event that got teased over the course of months, culminating with a lot of members (on the main channels or their own) streaming their live reactions to the new generations' debuts. And then even after debut you had a bunch of holomembers sharing their thoughts and hyping up the new girls more, how they want to collab with them, how they got to chat with them off-stream before, etc.
Even if you didn't care about Advent or ReGloss, Cover made sure that everybody was aware of their existence and now they're regularly part of collabs everywhere you go.
What did these new Niji guys get? A tweet, premiere dates, and nothing else. Other nijimembers straight ignored them and overlapped en masse to cannibalize the viewership. They may even throw them under the bus in the future just to secure their own positions at NijiEN. This happens every time.
