>>3897060in the case of HoloEN? only two had extensive vtubing experience prior. One had dabbled in it, but only had surface knowledge of the tubing.
Across all gens though, EN was if anything the outlier, and not in the way you think. There are many JP gens that straight up have no indie vtubers in them. Here's a list of notable holos who were not indies prior to hololives:
>Botan>Matsuri>Coco>Haachama>Subaru>My Oshi (pic related)>The Entirety of Hololive Gamers>The Entirety of 3rd genIf I were you, I wouldn't be surprised if EN2 has 0 former indies in it.
