>>34740516If we're only talking about the girls and not the stars, Marine reported a 20% female audience, and Matsuri and Towa are also relatively high. In EN it's probably Kiara and Mori, though there are more femsaplings than you'd expect.
As for the lowest, I know Subaru reported her audience as being only like 5% female, though I wouldn't be surprised if some holos were even lower.
