Taken from nyfco mostly, been following along and double-checking:
Josuju Shinri = Lex Parte
tweet comparison - basically a self-dox
some of his friends as Lex interacted with Shinri's tweets first or exclusively
content interests match
Machina X Flayer = probably Ais Riale
based on similar tweet style, Melty Blood, mannerisms
tweet comparison
Gavis Bettel = Lord Commander Chaos (before that, Zuthar13)
based on art similarities with LCC's content. For example his
irl brother did most of his thumbnails as LCC and Zuthar, and seems to be continuing. Background artist seems to be the same too.
artist follows/likes
friend follows/likes
example artist connection
Banzoin Hakka = probably
Hiraga
based on very similar tweet style, one friend follow, "break" timing
I would say Lex and LCC are confirmed and Ais and Hiraga are very likely.
Presuming that's all true, my takes pre-debut:
Shinri/Lex will probably be a good talker with good stories (he's older and went to law school), but I will likely bounce off his content. Good for the female fans though. Apparently he can play FPS fine so he'll be good for the Apex/Valo guerilla collabs. Also a fan of StarsJP so maybe we will see more interaction between the Stars branches.
Flayer/Ais is a good all-around streamer with a bratty personality. Not quite the shota that some people want but the bratty kid for sure. Can voice act. I'm on the wait and see train regarding his content, but he'll likely generate some good clippable moments. As an aside Ais, Lex, and Hanbyeol(Altare) all knew each other.
Bettel/LCC is that guy who's been on the gaming content grind for 10 years. Some people say a more gaming less chatting version of Vesper? I'm on the wait and see if his content catches my interest.
Hakka/Hiraga is a kick-ass
utaite, with a voice more suited to rock and harsher vocals. Might follow the Axel route of not having much streaming experience. Honduran living in the USA. Excited for any singing he does, he has one hell of a voice. As in, he can
scream (aside: Xandu became Ike Everland).
