I'm most hyped for FuwaMoco. My autism would like to call them the Abyssgards, for formality, but Abyssgard is a hilariously unfitting surname. The hype is definitely at least partly due to their shared channel being unprecedented in Holo.
Cover would not have designed twins beforehand because they would be difficult to cast. So we can infer they had major input into the models. That is itself a deviation from how their senpais got their models. When did they discuss their models though? When did they apply? Is this why EN3 took so long? (I don't actually believe that.) Or perhaps they were scouted? If they were, designing the models for them and giving them a shared channel would be easier on Cover's corpo sensibilities than if they weren't.
As for GGN, i dont think its them mainly because of the 2024 idol thing. but who knows? maybe that was just a distraction.
Yesterday, I said in the main thread that this is the reason I counted out the GGN twins. Not because of the workload (they could pull a Calli), or because of whether they're allowed (contracts can differ, but quite a number of Holos moonlight). But because they described Amerily, their 2024 idol project, as their "final chapter as idols, however long it takes". If they said this knowing they got into Hololive, that implies they don't think of their Holo gig as a chapter of their idol career. They're free to think that as long as they're happy to do the Holo work, and I don't think anyone should think less of them for it. But certainly many Holos think of themselves as idols, so it's weird.
Too many other things are lining up though. Twins (with experience sharing platforms and earnings), EN/JP fluency, Vtubing experience, idol aspirations, similar debut thumbnail to the GGN debut thumbnail, tweet style. Someone asked if the V&U twins spoke Japanese - from the wiki, they spoke English, Japanese, and Korean. But they disappeared for what the company described as personal reasons, so they may not be ready to reappear. Ally and Sally are a much closer match overall.
If FuwaMoco are Ally and Sally, what I think they want is to be IRL idols, and to use the Holo money and exposure for their last shot before they age out of it. Which is sweet in a way.
I'll probably like the others as well, but I don't have long walls of text to write about them.
Also Lui schizo'd over FuwaMoco and now they're scared of her lemao.
