imangine thinking holo rigging is much better than niji’s. fact is all of holo rigging sucks – they sway back and forth so much, their faces look so one dimensional and like a triangle when they turn their face to the side, their mouth rigging is atrocious and they can even show basic expressions without a toggle. While niji has bad rigs too esp the older models, their good rigs blow holo’s shit out the water. voltaction members and pretty sure the newer members can even pull their tongue out and puff cheeks without a freaking toggle
Holo’s 3.0s (i think) can also do the tongue thing. And the thread isn’t necessarily wrong, Niji riggers ARE limited because Niji has a specific app and they don’t want to outsource. Some holo rigs, like Nerissa and Axel, do have strange angles and mouth rigging can be atrocious, but we have to remember that they outsource for rigs, so it’s less holo’s rigging being weird and more like some riggers have weird specks.
I will agree that I enjoy how little niji’s sway. it’s easy on the eyes.
what’s the benefit in holo outsourcing when the end result is even worse than niji in-house rigging. there are far more good niji riggings than there are holo riggings. good holo rigging is non-existent
I don’t agree that holo has no good rigging, I think bettel has amazing rigging, but most of them ARE hit or miss. And the benefit to outsourcing? I’m not too sure on that front, but I’m sure it allows for each of them to stand out, but you could also see that as a negative because it only highlights how some of them are good while others are bad. With niji, almost everyone is the same, but some are noticeably worse, all of noctyx, or noticeably better like ren and wilson.
okay ONE holo rigging is good. still far more good niji riggings than good holo riggings
lmao chill
??? holofag no need to get hurt bc people said niji rigging is better
I am actively saying that Holo has hit or miss rigging and even said that I enjoy Niji rigging better, what?
if you dont trash holo rigging you are a holofag periodt
But I did???
ahhh whatever
you said hit or miss you have to say miss or miss
holofag no need to get emotional over people not liking holo rigging
bruh dramafags really be boldly spreading lies they read from vt
https://x.com/VTShineko/status/1726659216054894900?s=20
let Luke do the work. iykyk
some other posts there said they dont update rigging lol like.. ??? and honestly, more “complex” rigging isn’t necessarily good, it just looks unnatural most of the time.
Yeah.. it was bothering me whenever I see these comments, besides swaying back and forth like crazy at weird angles most of the time, some of them have question face and neck rigs?? It’s like a floating flat face
Like yes niji has some real stiff rigs, some can’t even tilt or twist ( ex. Kandas debut model moving range)
But there are reasons for such, and if anything, nijisanjs models rarely look like they have wrong perspectives and unatural transitions. It’s quite accurate usually
it’s relaxing to watch niji rigging, not very distracting and the mouth shapes feels like more accurate now, which imo, is much more important for my immersion because talking is what they do most.
hololive feels like they’re gonna jump out of the screen or bounce around like water balloons
Agree with this.
Always feel weird whenever I watch other vtuber outside niji (corpo or indies), their mouth movement and shape not matching with how they talk, either too fast or too slow with weird shape. Also, I don’t like how bouncy and how they always look above or down like many of holo models.
Every time I see the holo models moving like no tomorrow I wonder wtf is the actual people doing. Like are they moving like that irl or is it like when someone puts their mouse sensitivity to the max and when the mouse moves just a little bit on the screen the cursor just goes zooom
holo models sway like drunk uncles and their mouth rigging sucks. indie models bounce like water balloons and have over exaggerated expressions. they give me vertigo. these people saying they more realistic are fucking nuts no one moves like that irl. yeah some older nijis are overly stiff but most of them are actually more realistic in movement and facial expressions

wtf?
> its a response to a Khyo tweet
pack it up. we already know they’re misinformed so no need to bother.
Talents? It has to be Holofags. Don’t use your treasured time to focus on them they always complain anyway. Livers accident cough they would save they have been abuse.
pako sensei drew shuppio ^~^
https://x.com/pakosun/status/1726785177177960930?s=46
uooohh pako drew another nijien art. I wonder if he is interested in drawing like the next wave of nijien. break your curse, pako-sensei lol
The new guy is playing melatonin and is already at 2.2k ccv while zali peaked at 1.2k his entire stream.. yeah guys I think the branch is done for
Go the fck away ccv holofag
how deep did that tongue go?
So deep they cleaned yagoo’s colon
op) you guys call this bait but I call it just pointing out the truth. niji’s bad reputation and the continuation of just pumping out waves is not doing them any good. Armis were welcomed with open arms because of how long it took them to arrive and also because the new guys were needed, while TTT was met with negativity because “oh ANOTHER. new niji wave.”
I want the livers to thrive, but they can’t do that when they’re competing with a new wave every few months.
holo debuted 18 talents in 2023 holofag
niji debuted 17 (20 including the latest jp wave announced today)
so? what was the spacing for those debuts? they were prob longer than 3 months. All the debuts also targeted diff audiences. You can’t tell me that the same people who watch advent are going to watch armis. Unlike holo, niji is stretching the EN fanbase thin and they don’t seem to have any intention of expanding the fandom either, which exacerbates the problem. Most of Krisis and Kunai are already 3views while armis only seems to be going up, so we can see what is working and what isn’t
Dumb fucking b1tch

bruh armis is on their 2nd stream debut buff.vanta’s ccv is on par with bettel your top stars en and wilson hits 1k ccv without raids more often then the other stars.
Tbh, i do agree niji should do a new approach with debuting time but at the same time i dont want a fandom so big that bullies livers/talents from different company or outside of their company and continues to spread misinformation from channels that are biased and not from the livers themselves.
The amount of misinfo is the one of the main reason why that viewer ship is that low. The amount of bullying that happened to fans and livers that whenever a liver speaks up(+)
(+) they are called boot licker. Livers hace voiced their frustrations and their compliments towards management. They are not held at gun point.
Frickin Aia had said she thought of graduateling cuz she didnt feel accomplished but was offered to stay cuz they believed she is doing fine.
Didnt care about ccv when she spoke up about that, and idk why other people compare different people and target audience.
Kunai bait didn’t work yesterday huh? Niji’s bad reputation that was BOMBED bc of these dramatubers and holofags that contributed LARGELY to it? Admittedly, both ankr and cover can do better as corp. but you also need to rmb that these companies work differently too.
These livers can still live very comfortably despite your problem with their low CCVs or wtv. Hell they can even pay off their debts too.
focus on supporting the rest of STARSen that don’t have debut buffs lol
Open arms my ass. Jurard immediately get shit on when A-chan told him to do holotori dance and when he tell the whole world that his kamioshi is Pekora. It stopped because of Kiara’s 3D drama.
how long did does your tongue stay?
If you wanna numberfag using holostars that you dont even claim as part of Holo, Zali had 100k subs in less than 10 days of debut. Same goes for all of Krisis.
How good do those Cover shoes taste, corpo bootlicker?
zali makes more money than you
why melokoto stole en livers seats, we could’ve had talented people like amalee but they stole her spot!!!
amalee is annoying no thank you. I love melo
bruh these tourneys are are taking up my weekends (jp & en). i’m happy so much is happening tho can’t wait for the upcoming weekends
More JP for kotomelo to collab with
Dude either pulled a seraph or is a completely new hire from non VTA Hires?
WAIT it might be Chihaya 2nd gen
I hope its chihaya
congrats anon it’s chihaya
https://x.com/iluvu_sm/status/1726802475691524417?s=20
wtf kestrel true
I can’t believe they separated Chihaya and Kuno like this…
Plus they ALSO wasted Chihaya’s long hair appeal as well. The fuck…
I was hoping for Sonata since the aesthetic and colors lined up
Omg I miss sonata
And yeah long hair rip…
I can’t believe they separated Toto and Azusa like this. Their collabs in VTA were hilarious.
Azusa already debuted somewhere else. Look at riotmusic’s recent debuts and you’ll see someone familiar.
Chise Itsuki?
Or Jill lmao I can’t tell but I think u Jill?
its Jill. Compare her model to her Azusa png you’ll see the similar hair and face.
idk but if what anon said from the last page is true and all VTA students get their own YouTube channels when they start VTA (I.e. girls’ accounts were made last year) then I think they hired the guy from the nonVTA auditions bc his account was made September this year
Newcomers look so fucking good argrr
VTA kids always do well and are welcomed back with open arms. Can’t wait to see if the dude has a pl or if he’s just a random dude they scouted
have they recently scouted anyone? I feel like they’re relying on VTA entirely now and have no need for scouting
mana, wen, kagetsu, inami and some idios girls are not from vta or at least not from the public facing vta branch. they could either be from the non-streaming vta auditions or scouted
Others might or might not be from private VTA classes but Mana is 99% a non-VTA hire because Rou mentioned not knowing about him up until right before his debut. Only then he was able to invite Mana to join the S.C.R.E.A.M cover.
“Relying on VTA entirely now” uh yeah they use their resources to train/teach them to become better entertainers I hope they hire them as niji livers?? also there has been non vta hires as well like how hard is it to look up these things
why melokoto skip vta, they couldnt wait a year to debut with these models instead?
Awesome revolution
I saw one of their channel saying it’s been created last year December 2. We’re they planning to debut them last year??
could been for anyone and niji just handed the info to log in
All past vta student(from gen 2-3) have youtube channels made for them when they joined vta , it was just a waiting game if they would join niji or be gone forever
damn, i think i need to sleep because it looked like the pup girl had a camel toe for a moment.
and the dude????
he skipped vta…
Koto schizo don’t even try…
We still dont know who they are probably someone from vta that didnt need streaming training like some of the heroes, but some jp vta fans are saying that his tweets is very similar to how chihaya tweeted. So it might be him, confirmation will be when we hear his voice.
Can someone explain how vta works
They have two types of audition one for people with streaming experience and one without. Ppl who dont have experience go to vta streaming training “public vta” as some vta fans call it, these are the people that we see streaming.
The red girl reminds me of zeta from granblue fantasy
What with the previous pages disappearing?
Lmao antis mad
Why why why melokotoclaude could’ve been this jp wave why why why did they skip vta WHY WHY WHY WHY MELOKOTOCLAUDE IN EN!? WHY!!!!
when will riku tazumi debut as a vtuber?
It’s pretty cool that Vivi will go a full month without collabing with any male besides Claude who is in her wave. I remember MeloKoto collabing with Luca and Mysta frequently when they debuted but not collabing with anyone from Lazulight or Obsydia and that rubbed me the wrong way.
Go wash your brain
What’s cool about it? Do men and women having a conversation over the internet make you uncomfortable?
No one is gonna eat what u cooked
Suika tournament and new Jp wave!! Keep the good stuff coming
Also, I think the new guy’s mama also Axia’s mama
Here they are a trio, 2 girls one boy (theyre like counterparts of EN TTT but probably not theyre also fantasy themed)

https://twitter.com/nijisanji_app/status/1726797580510834724
the production quality???
could one of the girls be fila?
nope nvm the names are right there, the girls are both VTA
i don’t remember a guy in vta with that name. he’s probably from the non-streaming vta audition
