She can't be overlapping everyone at once, and a person who watches Aia when Pomu isn't on still doesn't become a 'core fan' because they still have non-Aia priority.
What Nijisanji does, and I think people overlook this, is they are in a constant state of keeping the attention on the branch. There are no 'dead periods'. Debuts happen every few months, merch is always being released, EN is always involved in big events now, new outfits, anniversaries etc. ILUNA, despite not reaching the numbers of their predecessors, attracted a large fanbase of people completely new to Nijisanji. Scarle is one of the most lucrative EN girls despite her relatively low viewership and insane streaming hours because she acquired people who only give her money.
A lot of people egregiously describe it as 'quantity over quality' but it's actually 'strength in numbers', and the most important thing for Niji is to do better at balancing where the attention goes so they can all enjoy a steady stream of new viewers.
HoloEN has a totally separate set of issues. Much like Facebook, Hololive have the problem of simply not having enough humans left to mass appeal to. Everyone in the west is either already watching them, watched them and decided to go elsewhere, or is aware of them and don't bother. This is why Council peaked in their first month and then torpedoed. The only reason ID3 succeeded is because they actually attracted Indonesians for a change. But future EN generations will just be devouring the existing fans inside the walled garden.
