I’m still not sure why. For the corporate ones, like Hololive, I’m quite sure it’s just management driving it for audience engagement, at least on most of them. Lesbians are very fetishized by male audiences, so it appeals to them, while also keeping parasocial behaviour alive, as those men can imagine a relationship with the vtuber since there’s no boyfriend in the picture. Nonetheless, there’s a couple where I’m sure they’re pretty gay, Ollie and Kiara come to mind, and OkaKoro as a relationship seems genuine enough as well.

For more indie vtubers I do not know what’s going on with the queerness. It’s either faked like how I assume it is with most corpos or there’s some sort of selection bias. Maybe the type of woman likely to become a vtuber is also the type to have grown up in male online spaces, and assimilated some of the attraction to women during their puberty? That rough idea would track with male vtubers seeming pretty hetero overall, at least to me.

I’m just taking random guesses here, might just be talking absolute bs, I’m not sure.
