The thing with Holos is that even if they have passionate female fans they're still idols and will mostly appeal to their male fans, and even if we ever get a female only Holo the Holobronies would still watch her and repel potential females to join, I'm not saying they're gonna prevent all girls to join the fanbase but will for sure make them the minority.
For example Vesper has 50/50 male to female ratio, I think that's impossible for a Holo to achieve.
>>51340012As you said she was surprised at having female fans at all, I think Marine would be closer to a sistubers but she still shows her tits and ass a lot with attracts more males and repels female viewers.
>>51342498Mori still shows her tits and her attitude seems more towards the: "Pick me guys I'm just like you! I'm one of the cool girls you know?"
Although I do think Suisei is the closest, I don't know much about her but I remember seeing a clip of her saying she didn't wanted to be sexualized and it's clear that she want the mainstream audience more than the idol one.
Nijigirls would also be really close but the thing is that I already hated them rumao.
