Hololive are idols, HoloEN should be idols in theory too. Other companies make no attempt to pass as idols, they are just vtubers. Tho many try to appeal to the CGDCT audience or GFE market.
If all you really want is to avoid males on stream here's a rundown of some
>Nijisanji
Avoid it like the plague, it's basically the NTR company, all the girls enjoy NTR and do it to their fans all the time.
They will surprise you with a guy at all girls off collabs, they will pose together rubbing their hands making fun of their fans, they will have their streams randomly raided by a guy and proceed to act like a retarded high schooler with a crush.
>HoloEN
Split in the middle between those who have semi regular collabs with a few males and those who do not.
Very easy to avoid the males if you stick to the good girls, and even the whores mostly avoid the guys except for maybe one collab every week or two.
>idol
No male interactions on stream to my knowledge but they have interacted with males on their chat on stream. Despite the name the CEO clarified "it means idol in the normal sense, someone you idolize, not japanese idols" which seems like an odd thing to bring out of nowhere, so perhaps he's just preparing for an inevitable collab with males. He said on an interview that they planned to have male vtubers debut at one point but changed their mind.
So between the debut of gen HE and EN they saw the chinese profits on NijiEN and started to consider males and then saw the shit storm that happened in HoloEN and decided it was not worth it.
Two of their members have a few red flags meaning they might want to interact with males later. Proceed to that corpo with caution. Beware the eel and the prince.
>Phase Connect
SAD GIRLS COMPANY is not a meme, it's the company's identity. They will never debut males.
They have no proper rule against males on stream, but all of them are aware that their audience does not like it and they do not resent their audience for it, so for the most part they go along with it.
Some have never interacted with a male on stream. Male on stream or male interaction is historically very rare in the corpo, but it has happened. One of them stopped her GFE ASMR to voice chat with some guy she knows for 20 minutes, an actual NTR incident that drove the fans insane. Another one is aware that guys hate guys on stream and avoids it, but still has done a few interviews with guys in a very professional and formal way. Some of her fans hate it, others don't mind. It's on the same level you could see on HoloJP.
I'd say it's a very mixed bag, if the mere possibility that a girl will interact with a male on stream is too much for you to handle avoid them, but if knowing they won't have males and that male interaction is extremely rare is good enough you can go check them out.
>EIEN
New corpo, no male interaction as far as I'm aware. But the company leans heavily into coombait, so I don't know if they will have an issue with male interaction considering they are not marketing purity or GFE.
>Production Kawaii
0 male interactions on stream, except for one girl who sometimes does big collabs where there might be some guys mixed in, that's the only exception. That's actually regulated, it's all in their rules. No 1 on 1 male on stream, but the big collab option is ok.
They had one member who interacted with guys on her chat on stream but she's gone now.
They have rebranded into an idol company, so its a good bet.
