The id girls are a really the fourth possibly the fifth largest language for vtubing. It's Japanese ,English, Chinese, and then Spanish or Indonesian without a cultural penetration of the other languages. Indonesian language and culture has less global relevance than Spanish, Hindi, or Arabian based languages. They are a runt of the giants of languages. If you are more niche you can get a concentrated audience for being representative of a entire language. Like French, Italian, and German vtubers get a boost for sparse compared to the big five. Like hololive or any other corpo would never launch a specific gen for these languages but they get a Cecelia and a raora to boost global awareness for the brand. Like realistically id for hololive was not even their third or maybe their fourth priority when it comes company directives. If the china branch had continued till today there would be more Chinese members than Indonesian members and if they were able to work out a deal with South Korea cover corp would have as many Korean branch members as Indonesian members by now. Theres a reason there hasn't been a fourth gen theres also a reason why they launched them with 3 a gen. The talk about this is just downstream from the fact that id is like the Xbox or the dreamcast where there is a fan base for them and they are one of the big three but they are for intensive conversations on the periferey of being relevant. there is just a gap between the top two and them. They are closer to phase connect and the immediate post selen departure nijisanji.
