Time for a NijiEN ILUNA scouting report (aka shit I cribbed from /vt/). Remember, any of this shit could be wildly incorrect:
Maria Marionette: leading rrat seems to be that she is
Himechin, a fleshtuber/twitch streamer. /NijiEN/ has already taken a liking to her. Definitely a strong selection, if it is her. She is also 100% Pomu's type. She announced a hiatus from her activities and she does sound a bit like Maria, but I'm not sure that I'd call this certain as of yet.
Kaneko Kyo: main rrat seems to be a Youtuber named
Quinn Benet. Basically the polar opposite of Maria - /NijiEN/ is already doomposting about him, and I can see why. His content seems like low-tier clickbait shit. Frankly I'm kinda sad that this is a strong rrat (very similar voice, and Quinn announced a hiatus from his channel). Then again I thought Nina would be terrible and she ended up being alright (imo) so maybe I'll give him a chance.
Ren Zotto: I saw some people linking him to
Jordan Sweeto, aka
Sweetotoons. A few days ago people were floating his name as a potential Tempus member. I think it could be him, the voice is similar enough. I feel kinda indifferent, he seems alright but not really my style of content creator.
Aia Amare: One person named an indie vtuber named
LuKya as a possibility. According to her bio, she's French but also speaks Japanese, English, Vietnamese, and Chinese. Aia did tweet in Vietnamese but has not hinted at knowing French as of yet. She graduated back in April. She seems pretty good, but not many posters seem to have jumped on this rrat so maybe it's not very strong.
Scarle Yonaguni & Aster Arcadia - haven't seen any theories as to their PLs as of yet.
