This is gonna get downvoted a lot i guess but I have to get it out; while I do enjoy offcollabs between NijiEN and think they’re fun, I feel conflicted by the fact that if this is a confirmed offcollab between Nina, Luca and Sonny, judging by Sonny’s schedule it would fall directly before/on Lazulight’s 1st year anniv, and now the fandoms’ attention will be split between the two events when it should definitely be focused towards the anniversary, and this is coming from me, someone who is subbed to Nina and a Lucub/Briskadet as well. I understand that there may be issues like scheduling and such, but can they really not find a time that would not fall before such a monumental date for NijiEN? This really leaves a bad taste in my mouth and now I can’t even find the energy to be excited for the offcollab…
^ *before the anniversary, not before/on, I really shouldn’t type while being drowsy istg, now i got the dates mixed up, but yeah my point still stands
We can always hyped both events at the same time. It’s not unusual to have some important events clashed in vtubing.
if i see from the past few event, there will be a chaos ofc, but that’s between the boys. idk if they care enough about the girls or haters will causing some drama. let’s just see.
you both have different points but your statement have more sense than the anon below you and i feel the same way. should’ve thought things through, checking schedules and sht shouldn’t be too hard.
this reminds me of the Mysta UAkaraoke and Sonny Birthday totsu so much. Like mother like son.
i think we still can be supportive to both event. No need to bring bad atmosphere or creating drama like this.
op here, yeah on hindsight my statement do feel like ripe ground for drama and i apologize to everyone who feels like it’s smth i commented to start one, I only wanted to vent my thoughts anonymously here instead of twt where it has the potential to be seen by thousands. My comment wasn’t made out of hate, it was merely me letting off some frustration I have. That is all.
Ngl I feel the same way it does feel a bit weird and was also surprised since the anniversary is quite near. And as much as everyone wanted to hype both things I don’t know of that will work I even miss some things when off collabs happened. Unless they streamed the off collab stream way earlier before the anniversary and them hyping up or endorsing the anniversary too, then maybe it will work.
Nina working her ass off leeching on Luxiem. Wow. Is she not content being the most subbed female Niji En? All her new subs/followers are from Luxiem supporters. Tweeting things like “(insert Luxiem member here said this on discord lmao”. ??? Don’t f***ing come at me. It’s a fact that Luxiem hard carried her. She’s purposely doing these offcollabs with the intention of growing her channel, and not genuinely wanting to see her colleague/friends. She’s just proving that she couldn’t achieve what she have right now without being a leech. Sasuga, Nina.
If I were her i’ll do the same. Who don’t want money, her luxiem offcollab made good donation. Sasuga mom of niji en lmao
Just like my mom fr fr taking all the money lmao
i might think of doing the same but only when i’m in desperate need of money and fame i dont think i can be that shameless tbh
all the other girls probably noticed how she got her fast growth but still doesn’t do the same because they have some pride at least
Sasuga indeed xD
I also noticed that she goes out of her way to collab with the boys but not with the girls. I mean she’s closer to the ones living in canada and yet she still hasn’t done an off collab with them. Lowkey would want her to do an off collab with elira and do a totsu drinking stream. But I guess not, the boys are her priority I guess
It’s so blatant as well. Watching Nina always feels like she’s trying to sell you something and I don’t like that feeling. I can’t put my fingers on it like I don’t get that vibe from anyone else
THIS ANON, THIS IS WHAT IVE BEEN FEELING. It’s like this desperate vibe to fit in and be liked…. idk
She’s extremely sus, even with her pre-nijisanji debut clips where she defended some toxic person related to her (i think) sub count
Is there any reason why she’s the most subscribed to among the girls, I can’t put my head to think of a reason, sorry if this was harsh but I do think she doesn’t deserve it
makes her content involved around luxiem mainly
i’m not saying leech or anything like a hater but it is a fact most of her new subscribers come from the luxiem fandom
also she play with the yt algorithm like spamming shorts, i guess thats one thing appraiseble she’s good at marketing herself
her subscribers shot up after the off-collab
It’s Luxiem. You’d be surprised how many of en boys’ fans who don’t watch the girls only know of Nina and Reimu and think she’s 1rst gen.
she roleplays as Luxiem’s overdoting mother, ofc she’ll be the most subbed one
Is she going to ID to meet mika or something?
OMG MOMMY FOR REAL
she lowkey enables the babying of the niji members, especially the boys
she’s allowed to treat them how she wants because they’re friends, she’s closer to them than the fans + she’s established this ‘mom of the group’ persona.. the fans tho are not… and if the boys are uncomfortable or want to speak up about it for it to truly stop like shu they will..
(cont.) so in a way, it’s kinda on the boy’s responsibility as well.. if you’re only blaming her, whiteknighting for the boys, then you’re a part of the problem in babysitting the boys as well!!
Of course it is also the responsibility of the boys and fans, i’m not denying that at all. i’m saying that she may have influence since she often says stuff like “awww, baby…”
the boys literally call her mom lmao.. its just the luxiem / noctyx fans to be honest..
im not a nina viewer.. but we can’t really blame other livers for what happens within the boys’ chats or the attitude the fans take towards them..
if any honeys are christians you should think twice before supporting her.
she just insulted Jesus today, and calling Him , the w word that I cant even type it.
Yes if you arent christians or if youre atheists you’d be happy and “it’s nOthIngBuRgeR” but insulting other religion is crossing the line.
insulting your viewers’ religion is basically insulting your own viewers.
nice bait lol, good try
what bait? https://youtu.be/B3q4R2Ay7a0?t=16120 check this yourself
pendejo lloron
I’m a Christian but Nina was just asking if he was a “w” not insulting. She was confused since the chat is telling her that “chucho” means Jesus and w**** in different languages. Don’t make it an issue here.
Can someone tell me what does w word stand for ? Im guessing witch or wizard, sorry if this was disrespectful I genuinely want to know..
w word = w***e
Anyone knows if the karaoke is uploaded somewhere? Thank you!
Today’s karaoke stream is just peak content
She’s so perfect for the role. I watched a lot of her collab streams and I love all of her interactions with the other livers because she knows how to match their energy well. I don’t get why most of the people would be mad/jealous of her whenever Nina interacts with the other livers especially Luxiem. She knows how to set boundaries without making them feel uncomfortable and be entertaining at the same time. People should really just stop being delusional and touch some grass.
Came back and saw this comment. Choked on my tea.
I was given a link to another comment and was just scrolling. This comment…..did not age well. Lmao.
yoo this will age like milk and its on page 1, very pog
https://youtu.be/oC3YBN1Kabs Oh she can actually act well
NEENER SPACIBAAA
Is there something this woman didn’t do in life? Not only she already worked everywhere but she is also multilingual damnnnn
At first, i thought that her roleplay as Ethyria’s mom was very cringe, i mean, some of the things she would say during their collabs was very cringe. But now i’m so used to it, it feels like i was brainwashed.
Am I the only one who doesn’t like the mc drama between Nina and Pomu? I know it was just a joke and they are fine with it. But it sounded so real at that time. I think Alban did take it seriously and tweeted an apology (deleted now). The atmosphere was so awkward. Esp after nina talking about reporting to the manager, I didn’t feel comfortable.
It is ok to create fake drama, but plz next time don’t make it sounds so real. And at least inform others who are in the collab, so that they won’t feel awkward or guilty about what had happened.
I am sorry if I am overreacting to a joke, but it just made me feel uncomfortable. I just wanted to watch a chill minecraft stream 🙁
wait, what happened?!
Was it because of someone mined the glowstone on Nina’s tunnel?
no, this happened last week i think
What? What happened?
for anyone wondering, op should be talking about the 4/8 mc stream with alban
I remember luca stopping them and elira freaking out .
And also i remember alban goes invi then accidentally hits pomu then luca chased him ahhahahha
looking at this now it would have been better if you mentioned the “dying channel” thing, so many things happen in NijiEn MC i also thought you were talking about the glowstones
Man IDK but out of Ethyria she feels the least genuine and I find it weird she’s the most subscribed to in the group. She also doesn’t match the wavelength of the other 3 when they’re together, kinda like a buzz kill when she talks.
She doesn’t fit in with the vibes✨
I know her from Luxiem, end up liking her but I just wanna to say this branrot I have:
She is actually giving extra effort trying to bring Luxiem member closer. I have this under weird sus that Luxiem member may have some personal problem and Nina alway doing an extra effort to get them closer. Why I said this? Because she didn’t do much with Noctyx = could it be Luxiem have some gap wider than Noctyx?
Well I could be too soon judging this but my sussy meter just keep rising after hearing what Nina implied on her stream about Luca (specifically)
but whatever, I found myself like her personality more and more
*her comment abt Luca didnt do plane after off collab stream
she’s just a leech
Shut up gachikoi
came back to say that u were speaking the truth lol ppl really thinking ur a gachi when ur just speaking facts
anon spoke the truth when others are afraid to tell it
こんなに外と中が一致するV初めて見た!最高か!!!!!!!!!大好きだよニナママ!
Her name is Anastasiya Bila and her was interviewer in the Hearthstone ESL (https://www.youtube.com/watch?v=8Bvq3IY4Fcg&ab_channel=Lamborghiniaccount) and then she became Community Manager for the XSplit (https://www.xsplit.com/pt-br/blog/meet-our-newest-community-manager-anastasiya-bila-aka-obezianka)
oh my god that interview is actually so cringe LMAO i couldnt get past the first awkward handling of the mic LMAO why would you put someone so talkative and someone who doesnt leave their room ever, together like that fakdjfajknfakjf WITH ONE MIC
Wait so she isn’t actually blonde, i just knew this. But it’s so nice to see her irl, hope ppl doesn’t do anything crazy with this info
No wonder she got to be around so many places, and she’s good at being a leader figure imo
She’s seriously so cool. I’m not surprised Nijisanji hired her considering she worked for fricking XSplit
oh god what an interview lmao that poor awkward gamer dude. thank you for the links tho. and ppl say nina doesn’t have any talents… bro she’s had more experience and talents than any other nijis
She comes off a bit flat when put beside her genmates.
LMAO WHAT IS THAT INTERVIEW ITS SO AWKWARD
so she’s kinda similar to shishiro botan in terms of portfolio and also that interview is so cringe (as expected from those fanbases)
Now that Mysta mentioned that him, Nina and Vox are about the same height and Ike is tiny while Ike is around 175cm, I’m curious about her height now lol
She’s also 175cm (https://www.exploretalent.com/resume/anastasiabila/2070201)
Damn they’re like giants
shes pretty tall for a woman but it sounds like you’re around shorter men if you think theyre giants LOL no offense
If we’re going to talk abt Asian average height here (im aware she’s white) yeah she is giant lmao
she’s really tall omg for a woman tho idk for eu woman standards
but didn’t nina say she got the smallest bed bc she’s the shortest one?
She is very cute and beautiful!
Fun fact about her old username! Obezyanka means monkey in Russian
i love nina but im starting to get annoyed bc shes everywhere and im seeing her even on my soup
soup?? lol
wtf dude lmao
Take your meds buddy
yo i laughing so hard right now wtf lmao
close to the boys
I’m living for it.
Normal people with regular mixed friends are like that.
I’m sorry you don’t experience such normality in your life
stay pressed. I just said close to the boys >.>
most Chaotic Neutral vtuber
Does she ever keep to her schedule? Genuinely curious, it seems every week she over sleeps or rescheduled bc she has errands. She doesn’t even have a full schedule like other members who hold day jobs
i think thats just how she is?? i dont really watch her since debut but i also notice she doesnt have a dedicated schedule or often post her schedule late. i think she also mentioned it before she hate doing schedule
she really seemed to try and be on schedule when she started in nijisanji but like two months in it went sideways.. this is actually what bugs me the most about her, she used to be my oshi until I couldn’t freaking catch a stream live >:( but yes, this is just how she is.
btw one time she overslept and the viewers had i think Finana text her on discord where Nina said she’d overslept and Finana posted a screenshot of the messages on twitter and then later on the stream Nina got a little angry for her showing private messages but brushed it off quickly and that’s when I kinda thought that her last minute errands could be just her being unable to wake up on time most of the times.. i do like honest people better
Too many incels on this comment section.
Someone really broke down because vtuber had a boyfriend,lmao
Why the f*** do you guys care so much if a vtuber has a bf or not lmao
Their fantasy that all women want to impress their incel ass is ruined if women they watch get boyfriends lol
Lmao people give money to regular streamers for being entertaining all the time. If the only reason you’re giving money to a vtuber is because you wanna f ** k them or smth and get all P***y because you can’t then better go out and touch some grass, my guy
what does female/male have to do with anything? she’s just an entertaining streamer, that’s all.
You do know that you give money to a lot of people who date or are married, right? Like the internet you pay to be in here, it goes to someone who has a boyfriend or husband.
I see a streamer who entertains me, I help support them. If I stop finding them entertaining, I stop supporting them. It’s not that weird lol.
Calm down sons, its just a drawing
I started watching her lately and this comment section is confusing??? What did Nina/her past do???
far as i know, (monkeyism)she doesnt
sorry i accidentally clicked enter lol, so far as i know (monkeyism) she doesn’t really care abt her viewers and even roast them and brag up abt politics and stuff one of her viewers on twitch mentioned abt the fact that she only talk/cares abt the one who give her money (sorry my english is bad) there’s a video abt this on bilibili
Man this comment section is wild.
go touch grass kontol
So why does that matter, it’s nijisanji they’re all chaotic
Isn’t this the b***h the ruined Millie’s collab potential after the Unrailed collab? Millie has lost her chaotic charms in subsequent collabs after that. Yet Nina did the same thing Millie did in the recent Uno collab with Luxiem. People in vt even called her out on her hypocrisy
Right lol
timestamp and the video source?
It’s Nijisanji they’re all chaotic why does that matter to you if Millie loses her chaotic charm dont blame nina for something someone else can control
what are you even talking about
You are such a clown, man. People cannot separate between being playing a character and being genuine.
Don’t think millie lost her chaotic charms, her fan base (and enna’s) lives off that s***. But yeah, nina’s hypocrisy on the matter is kinda cringe. Dom’t think she really fits well with her own Gen. In fact they seem to doing better without her and with others. She didn’t even bring much to the table on thier 6 month Collab and she’s the one that hosted it.
Guys stop touching grass that’s weird.
Go touch grass guys
this comment section did not pass the vibe check
Man, y’all need some help
NOOO MY V CHUBA CAN’T HAVE A BF AND GOING OUT NOOO
IDOLFAGS = KILL.YOURSELF RUN VERY FAST HEAD FIRST TO THE WALL OR BETTER YET, PESTICIDE EASY AND FAST XDDDD !!!!!
Get your medicine, dude.
un/ NOOOOOO MY MOMMY CAN’T HAVE A BF T.T
rn/ d*** IS PROBBLY GOOD UOGGGH S3GGs!!!
Bruh.. What wrong with u guys???
U guys need to touch a grass
what is wrong with everyone lmao, just enjoy 🙂
The internet is a weird place
to everyone
touch grass fu**ers
Man, after all these years I thought this community has grown but it looks like western fans still don’t get the entire concept of the soul of vtubers.
Those are the < 5% schizophrenics from 4chan that can't stop yelling
lol I see nothing wrong with her – at least she haven’t got a bf after joining nijisanji like some holow**res from counsil
Incel detected
Get out holocu***ld
not gonna deny that ur an incel huh, incel xddddddd
not gonna deny that ur a cu***ld huh, cu***ld xddddddd
how is this even cu***ld explain lmao
cuc***ded western fanbase loves to sent superchats for t***s like Fauna and Mumei so their multiple boyfriends may enjoy free condoms!
did someone hurt you anon? I think you need more than a mental therapy, let people enjoy other people’s work, You’re an incel calling all women who have a normal relationship a bad name. that alone is by the definition of an incel. we don’t care they whether or of not they are in a relationship or not. what matter is that is whether or not they entertain us. that’s what matter . Both me and my girlfriend enjoy their content. if we don’t enjoy their content, we could you know….. watch something else? we’re living in the golden age of entertainment. like seriously , if you want to watch the quote on quote a v***in vtuber, than by all mean, go ahead, the doors are wide open . Like Miss nina said on her stream
https://youtu.be/OySsn26dsk4
also an incel like you reminds me of Plymouth shooting incident. it’s about an incel who’s willing to take others people’s lives just because women refused to that date him( gee… i wonder why). so my advice would be go see a therapist or better yet apply for mental asylum instead before its too late
Why do you cu***lds think that we’re incels? Enjoy other men’s d**ks if you want, but that’s just disgusting for us.
Mumei had 3 boyfriends at the same time, you may easily become 4th and may be getting some holonudes as well!
you really think you had any chance to F*** any of these girls? please….. i’m pretty sure their bf is far more gigachad than you
Eddie’s a total c*** (Fauna’s probably similar to that one CN member who was a total s***ty person)
Petra has a boyfriend you du*bF***
Look at Petra’s page carefully, dummy.
There only was some suspicions, and Petra herself said at her twitter that she has noone to date.
i’m pretty sure she said she’s never had a boyfriend other than in otome games, then again people can say stuff that’s not true but some people don’t care about someone’s personal life, only weirdos care about someone else’s life outside of streaming
WTF is wrong with yall? So immature sounding like kpop fans, but instead of bts or blackpink it is “Hololive is better” “No, Nijisanji is better”
Pomu and Kiara, Suisei and Toko, Matsuri and Hoshikawa, and many others are laughing right now at this deeply unconvincing attempt to create drama between people who pretty much lunch together.
She’s probably doing the Senzawa strat, leave her old community so that she could change her life around.
She probably did, people can change Senzawa would do drunk streams when she wanted, she also probably wants people to forget she made that viral OK Boomer song twitch streamer Neeko used on a tiktok a few years ago, Nina isn’t doing anything bad that will make people hate her, if they hate her cause of her past then that’s their problem not hers.
holofags are being proud right now but they forgot that they have SO MUCH talents who brought a BIG fu***ng scandal for example when m**na being impregnated by her fans oops my mouth slippery~~~
xD
Holo…
…you do realize she’s nijisanji right? You do realize who nijisanji are?
Boy, if you think that’s yabai, are you in for a shock.
interesting info, any further details?
leftist pig gonna ruin another good thing
How is she leftist? Gotta know so that I don’t watch her.
Because mentioning politics in media = bad amirite
I mean most people don’t watch streamers to hear their political opinions, if anything it’s to get away from real world issues. Plus most people who talk about politics on stream don’t tend to know what they’re talking about and their communities are an echo chamber. With that being said, it’s completely possible that she nuked her old accounts so that she could start over and get a new community because she either changed her views or decided that she wanted to leave the sphere of politics in general.
*watches the “I just wanna have s*x” clip*
…she’ll fit right in.
love her more now, she’s pretty based
hater gonna hate
The death of NijisanjjiEN
more like Hololive (even if it’s not obvious)
i don’t think so pal, seems fine to me most of their followers aren’t sensitive babies cause of someone’s past life, i don’t like politics but i know not let someone’s past decide if i want to watch them or not. I didn’t watch Millie when she was indie cause when she streamed it was always like 3am and probably didn’t think she streamed mainly in english
