Gen 2 - two streamers, two twitcasters, one successful ASMR specialist
Gen 3 - three streamers, one utaite, the biggest name in JP ASMR ever
Gamers - two NND personalities, one NND personality/vtuber
Gen 4 - one kson, one streamer, two utaites, one experienced streamer/vtuber
Gen 5 - one esports pro with a bit of vtubing, one big name vtuber/NND personality, one unknown twitcaster/utaite, one failed idol, and one big fucking mystery who might've been an unknown vtuber who's already made more than a hundred million yen in SCs under a year and shown an amazingly keen business sense when it comes to merch
Most of them don't have much of a track record in vtubing, if any, and I don't think any of them were the equivalent of 1 million subbed Youtubers on NND.
I also don't think the Western streaming scene should be any less diverse than Japan's even if you select only for those with otaku interests, so if Cover's scouts do their thing they should be able to get along just fine without needing to tap too much into the current pool of Western indies.
