Luxiem extremely feels like chilling with the homies. Their chaotic tendencies were blended well, and the fact that they are very talented in their own fields just makes it chef's kiss

As a Japanese fan of Luxiem, I have to say that Oliver Evans played a great roll to let us know about Luxiem. Oliver is very fluent in English even though he is a member of Nijisanji JP, and did collabs with Nijisanji EN girls.
The most important thing he did (I think) was he advertised the debut of Luxiem in Nijisanji Official Channel at the time of Nijisanji Mario Kart Tournament, where about 40,000-70,000 people were watching. Many Japanese people including me were not aware of their debut until he told us. Moreover, Oliver was one of the host at the debut, which made us interested in watching the streams. Literary he is breaking the barrier between JP and EN branch.

I'm new to Nijisanji (since Eden-gumi) , this is my viewpoint, and not used to writing in English. Sorry if I made mistakes.

There was also a lot of support for the Luxiem guys by the other Niji Members. Especially Nina Kosaka did a great job helping them out in the beginning and creating a really fun atmosphere. NijiEN just feels like such a close group of friends who have tons of fun together without any gender barriers. If we compare how isolated Holostars seemed/seem in the hololive community, it's no wonder why they didn't do that well.

What I like about Nijisanji is that they don't really seperate their female and male VTubers. They can just naturally and organically collab all the time. In Hololive the female and male talents are strictly seperated. So in Hololive collabs between female and male are quite rare and Holostars just feels like a side product of the company that they don't want to associate with their female talents.

I think the biggest point you missed was the zero gender barrier. It's just really nice having male/female relationship dynamics in the vtubing space. It's made the nijisanji En girls better (particularly reimu)  and made it more acceptable to watch male vtubers.

something i noticed that i really like with luxiem is how well the characters fit the people behind them, especially with their voices and personalities. their voices fit their designs really, really well--you don't have to be an english speaker to be intrigued by the way they all talk, and i think that's really important. no one would want to sit and watch someone speak for several hours if they didn't love their voice to some degree. well done on nijisanji's part for casting such talented people.

i also think the way their roles and personalities coincide can even serve as something to laugh at when they dont exactly align (e.g., mysta being a "naturally born genius detective" who's slow and comically dumb sometimes, or luca being a "scary and intimidating mafia boss" who radiates the energy of a lovable puppy).

its so interesting how well they can still pull off playing their characters even when their natural personalities don't align with how their character "should" act. it feels like a charming twist on the tropes they have to work with, and i think everyone loves it when characters go against the trope a little.

its just so fun. i love them all. stream hope in the dark

edit: also! i wanted to mention something in addition to luxiem attracting JP/CN fans to EN. ive noticed how luxiem encourages non-native english speakers to practice english more, which is really good! they're very supportive and even make efforts to praise non-native english speakers for trying their best with the language, which is heartwarming. ive also started practicing japanese more after watching ike and shu, and im sure im not the only one. its like two worlds that were separated by a language barrier are colliding, and im happy to see it.

Also small detail but the freedom to collab with anyone could attract people from other fandoms to subs to them. Like Vox and Luca has appeared in Ironmouse stream as a guest or as a stand it when she went to bathroom in the middle of her subathon. I think the best step for Luxiem is to try and maybe stream on Twitch once or twice.

I feel like another important factor is how Luxiem seem more caring towards the fans. Members like Vox, Ike and Mysta constantly remind the fans that they shouldn't donate too much if they are struggling financially, they address the dangers of parasocial relationships, and sometimes bring up the importance of taking care of mental health. It feels like they truly care about their fans and that they would put their fans's needs above their own. This selflessness adds more to how lovable they are because they aren't always just goofy and silly, but they also have serious moments that make them seem down to Earth.

I still remember when hater said that they'll failed just because they're male vtuber before they even debuted, I'm glad that they can prove them wrong.

Luxiem was literally what got me into watching V Tubers their humor and personality and also their debut was so good and funny ^^

being a nijisanji fan doesn't mean being a fan of every single nijisanji member, it means finding a liver that you like, you don't don't even need to know every member to be a nijisanji fan, bet even some of the livers don't know every member

I think another great factor for their success is that, it's not that their unhinged and very laid-off feel was exclusive to them. The whole of NijiEN has this lax feeling that you are just hanging out with a friend and not this professional under a contract, SPECIALLY in their crazy collabs. Hell, even if Luxiem still interacts with the community more, the EN girls were already pretty big into it too. Seriously, look for almost ANY clip that has Nina on it... You WILL see her in the comment section. So when Luxiem came and just added to that feeling tenfold... It got traction since it basically made the whole of EN better for just being there.

So I'd say the whole "family" dynamic that NijiEN has is also one of the helping factors IMO.

I have to add one element that makes Nijisanji pumping out waves easier for the viewers.

The ammount of collabs and the number of people on each collab, as well as impromptu collabs on every channel, makes it so that you can start by only focusing on one streamer, and then finding out who you like by watching collabs on their channel or channels where they appear.

I feel like with Luxiem the amount of collabs increased exponentially, or at least it feels that way since NijiEN increased by 50% at the time (now 50/50 male and female, doubling in three months).

There's also the main channel collabs, where everyone from the branch participates in a game show or competition of sorts, allowing them to show their personalities to the viewer-bases of all the other members.

Of course this isn't the reason Luxiem got popular, but I believe that's how they can debut a massive number of talents constantly, and why it can benefit everyone else.

I’m glad that Luxiem exists because in the beginning I felt like the vtuber scene was catered more for male fans, which is why Hololive never appealed to me.   Luxiem just opened that door for me and they are so good at doing what they do.  Because of that I also started getting into the Nijisanji girls as well (Rosemi is a such a cutie pie and Pomu is my spirit animal) and I just love their chemistry during collabs.

Imo as a girl theyr all also pretty interesting and have different things that draw me in.

Shu : laugh, singing,  quiet but gives witty jokes.
Ike : gap moe, calmness, sane man comments.
Luca : Lucy , optimistically hyper, himbo.
Mysta: sad edgy boi, endearing stupidity.
Vox : deep voice , old man humour , arguments.

- these descriptions can be quite overexaggerated so yea have a good day everyone <.<.

One of my favorite culture in Vtubers is the interconnectedness of the community, and I love Nijisanji EN isn't shy. The boys mesh so well with the girls' insanity, and really benefitted from the previous waves what to expect and boundaries set. So you see them in clipper's comments, collaborations with other vtubers like indies or Vshojo, and even interact with famous personalities. Heck, during "Speak of the Devil" by Ironmouse with Luca, they talked about their Monster Hunter game offstream session with Sykkuno. So that's pretty pog, and love to see how Nijisanji will shake up the vtuber world.

Not only the Luxium boys are immensely talented, their design are just right. And now that Noctyx is here, welp. While I personally think Luxium have much better designs, Noctyx personality grows on you. (And Alban Knox is gaining followers at ridiculous rate. I guess that the power of cat boys)  in the end they are just really fun and are very talented.

As much as I love Holostars… they are Yagoo's personal experimental group that he loved deeply and fought tooth and nail to not get axed. They we're a product of unfortunate circumstances and to me they were my JP "Luxiem" :(((

I think by far a good factor on why i managed to watch luxiem is just from the sheer amount of ads they were pumping out in my youtube and it caused a good amount of interest for a lot of people. Personally this caused a good amount of interest for me to check out their content at least once  and instantly got hook. This entire video effectively summed how i felt and was overall super informative
