>>76886039HoloEN was still new enough that Promise was formed around "Hey this Corpo is hiring ENs you want in?"
Yeah Myth was growing but Myth was it, and thanks to COVID limiting things the other more Idol aspects of Hololive was downplayed in the EN.
Promise was hired back when HoloEN was simply seen as a streaming gig and not an idol gig.
Now though they have a reputation they have a brand, and they're exclusive, remember Promise only had to audition once or twice to get in, Advent with perhaps the exception of Shiori who got in by being Western Vtuber pioneer, had to adution multiple times.
From Fuwamoco who tried to get in through EN and JP multiple times to looking at Biboo who admitted she created her entire PL career simply to build herself a resume to get into Hololive because her first submission got rejected because she had no experience.
These are girls who fought to get here, they weren't handed it. They know they are the chosen few and they banded together under that common bond.
For them getting into Hololive was a privilege they earned through their blood sweat and tears.
