so what are the predictions so far?:
bijou: beryl
nerissa: caitlin myers/ mom0ki
shiori: nasumi moe
twins: ggn girls/ ally and sally
didnt nerissa respond to a tweet in korean? can mom0ki speak korean?
Bijou's front runner right now is Waabyuu, who has historically played a lot of Souls/Elden Ring games, and Bijou made an unmistakable reference to Malenia's iconic line. She has said before she is thankful for vtubing as it introduced her to souls games, while Beryl and her past lives has AFAIK never played Elden Ring. From the list of notable retired vtubers, I think she's the only one who played ER to a big degree, and her voice fits the character, so I remain 70% confident on her.
And from what other people have said, Nerissa's Korean is oddly very polite for a twit, so people are speculating she is using machine translation and/or is having someone help her with it. As for her JP, it's basically very basic. As far as I see it, from the list outlined in the 2nd post of this thread, the only other songstresses are Miori and Beryl, but Caitlyn mogs both of them in terms of view counts for her songs so is the 'safe' choice. That said, Caitlyn's covers are ALL English, so Nerissa using foreign languages is a strike against Caitlyn, but I'd say it's still 50% confidence it's her.
As for Natsumi Moe being Shiori, the latest development with the eyes has IMO risen the confidence to about 30%.
