Honestly my only gripe with this is that they debuted a bit too soon. To put in perspective at least; Obsydia debuted really quickly after Lazulight, However, Obsydia was hinted at in their debut art with the glitchy pictures of Selen, Petra and Rosemi. So Obsydia we kind of knew ahead of time due to speculation and it also was for a total of 6 girls, 3 in each wave which is more palatable. Luxiem debuted with a roster of 5 which is what some would consider to be a "full roster" in terms of vtubing. That's all good and they (still) had/ve a ton of hype behind them. Noctyx is another group of 5 males which at this point even as a Nijisanji fan is bloating the roster of EN vtubers up a lot. Luxiem did really well so it makes sense to follow up with more males but I honestly didn't think it'd be this soon lol. Really I'm just employing my general Nijisanji mantra now and that's to follow who I like enough to actively follow (Pomu, Rosemi, Selen, Reimu, Luca) and just kind of half-follow everyone else maybe occasionally.
Kind of a tangent here in relation to this. Nijisanji has kind of proven with Luxiem there is a (growing) audience for male vtubers and that is being felt by Cover/Hololive (see the past whatever hundred pages ago where people were speculating on StarsEN) and smaller orgs like Tsunderia (which already has some males) and Phase Connect (Fishman went from "no males" to "maybe some males" in the Tsunderia interview he did). I just really hope that at least the smaller orgs understand that Nijisanji's males thrive the most from the freedom of being able to consistently have co-ed interactions/collabs rather than being like Holostars with rarely any interaction with the majority of their female peers.
