>>90809156-- Pomu
In Niji, was a 1.5k streamer, but showed consistent growth over time, growing to 3k and even surpassing some Luxnocs. After graduating her audience is significantly higher, around 4k, and seems to be going up.
-- Selen
In Niji selen was a 3k streamer, which declined to like 2.5k when she gave up apex near the end. These days her audience is about the same level, although a much higher ceiling for events and collabs.
-- Nina
In Niji could consistently peak over 1k when she wasn't playing super debuff autismo games. Although she started leaning into those more because, although the peaks were lower, she got a consistent devoted audience. After graduating her audience was significantly higher mostly because of the Vshojo buff.
-- Pikamee
Was at the 1k-1.5k level. Massive hype around her graduation and a pleasant change of character, combined with the Vshojo buff left her significantly higher than before. Arguably she also got a huge bounty for being so respected and having so much nostalgia attached.
-- Kunai
Her audience in NijiEN was 80% female, mostly pity viewers. After graduating she ended up marginally higher, although what's notable is the composition of her audience is now mostly male. So technically you could say she ditched her unwanted viewers and got the ones she wanted.
-- Coco
In Holo was like 2k-4k level. After leaving she ended up a bit lower because she radically changed her content.
-- Mysta
is in the same boat as Coco, radically changing his content and ended up significantly lower. The Vshojo buff does not exist for him, since he is a male talent.
-- Kyo
Is in a similar boat as Mysta. Radically changed his content and lost significant viewers.
My conclusion.
All of these people after graduating ended up at the same relative level, but marginally up or down depending on their change in persona. The only big outliers being Pikamee and Nina.
