It’s finally time to reveal exactly what the “Mysterious Obstacle” is! I hope you’re going to enjoy hearing all about her!
During my trip to Los Angeles last week, I became very, very sick – way too sick to record voiceover narration. Fortunately, the voiceover for this video was actually recorded before I traveled to Los Angeles, so you don’t have to listen to a coughing, sneezing YandereDev talking about the Mysterious Obstacle!
With that said…while I was making this video, I realized that there is some important information I failed to mention. Usually, when I realize this, I simply record some new voiceover and insert it into the video….but that’s not an option this time; my throat is way, way too jacked-up to provide a pleasant narration right now.
So, in order to provide you with the information that I really wish I had communicated in the video, I have to settle for writing out a blog post. Without further ado, here’s what I’d like to say:
“Are you finished working on Raibaru?”
Nope! The point of the video was to reveal the nature of the Mysterious Obstacle and justify her existence from a game design perspective. The point of this video was not to announce the completion of the MO. The good news is that very little work remains to be done; at this point, I only need to implement a handful of miscellaneous conversations between Raibaru and Osana. The MO will reach 100% completion very soon, probably within the next 2 weeks.
“When will you release a build containing Raibaru?”
I’m sorry if this disappoints you, but I won’t release a build containing Raibaru until Osana is finished. As a game mechanic, Raibaru’s existence only has meaning if Osana is present. If Osana is not present, there is no reason for Raibaru to be accessible in the debug sandbox. They are a co-dependent pair; there’s no reason to implement one without the other. In short, you’ll have to wait several months to actually encounter Raibaru in-game.
Yes, you can probably modify the game’s code in order to spawn Raibaru, but if you do this, the Raibaru that you spawn will probably not be an accurate representation of the final Raibaru. If you manage to spawn Raibaru and figure out a way to eliminate her while she’s still a work-in-progress, whatever method you used may be ineffective on the final Raibaru.
“How much more work needs to be done on Osana?”
I’m hesitant to provide a specific percentage or bullet-point list, since it’s possible that I’ll forget about something and remember it next week. At this point in time, the tasks that jump to mind are:
- Finishing work on Raibaru
- Implementing Osana’s suitor
- Implementing Osana’s “Befriend or Betray” side-quest
- Making sure that none of her pre-existing events have broken since the last time I worked on her
- Testing absolutely every elimination method and fixing all bugs / exploits / game design flaws that I encounter
Wow – it’s really not a large number of tasks, when I think about it! I’ll update this bullet-point list in the near future if I suddenly remember something important that I forgot about.
There are also a few other questions I’d like to answer pre-emptively. Please click “Continue Reading” to see!
“Is there a new build today?”
I’m sorry, but no. All of the work I’ve been doing recently has been related to Osana, the Mysterious Obstacle, or spoiler-related stuff that I can’t show you. Whenever I export a new build of the game, I disable a lot of stuff from being visible or accessible; all of the stuff I’ve been working on lately falls into that category. Even though I’ve been very busy, I don’t actually have a new build for you today.
“When will you release a new build?”
While I was in the “Pre-Osana Checklist” phase of the game’s development, my focus was on frequently implementing important game mechanics and releasing new builds as regularly as possible. Now that I am in the “Working on Osana” phase of the game’s development, it means that I’m spending all of my time working on stuff that I can’t share with you.
It’s possible that we have left the stage of the game’s development where you can expect me to regularly release new builds with cool features, since the game is nearly feature-complete at this point in time, and now my focus is on Osana. I still intend to release at least one video per month, but it’s hard to say exactly what those videos will be about, since from here on, almost all the work I’ll be doing is spoiler territory.
The next build will be released whenever I’ve compiled at least 10 bug fixes, or 10 additions/changes to the game that are unrelated to Osana.
“There are still unfinished items on the pre-Osana checklist! Save/Load, FPS improvements, and SNAP! What about those?”
I’ll implement save/load after Osana is finished, for the reasons described in this post. I’m tempted to strike “FPS improvements” off the checklist for the reasons mentioned in this post, but as always, I’ll continue doing what I’ve always done: making various miscellaneous improvements here and there, fixing whatever issues I find during the process of developing the game. (I’m planning to upgrade from Unity 2017 to Unity 2018 soon, and there are several reasons why this has a high chance of improving the framerate significantly – let’s hope that it works out!)
Those are all of the things that I wanted to mention! As always, thank you for following the development of Yandere Simulator!

A unity upgrade would be great. I think that unity 2018 has a few other features related to pathfinding and low quality models at a distance, though I’m not sure. Nonetheless, it will be a great improvement!
YOU SUCK YOU NEED MAKE RAIBARU TO BE REMOVED OR MAKE HIM COWARD AND VERY WEAK OR ELSE…….
Him?
Raibaru confirmed a trap lol
Raibaru is basically Rival-Chan! I’d knew she’d become a full student soon!
It’s a girl
OMG LOL I can just imagine a little spoilt brat like you whining endlessly behind the screen just because you think that “the game is too hard!” or “I don’t like the mysterious obstacle!”.You should either:
1) Stop playing yandere simulator because you can’t respect what yandere dev is trying to do.
2) GID GUD at the actual game instead of complaining.
3) Understand that not everything is about you.
or
4) Continue whining and sending threats that won’t even mean anything like the little pussy that you are.
Hope you work something out! 😉
Really dude you’re f*cking gonna give this little a hard time well then f*cking go you piece of s***!
And stop he’s a f*cking little kid! You need to stop being rude and start paying attention what he’s thinking when you say this he might be suicidal! Can you just stop bullying the poor guy?
I don’t think the mc master is 5, what 5 year old spells so good? There probably 15 or 14 ish.
And they put it in all caps 2 be rude.
I’m on Benjamin’s side sorry.
No one insults yandere devs hard work.
I’m sure you would be upset with this mc master kid if he did the same thing to all of you.
He also threaten yandere dev with “or else” which makes me upset to see yandere dev being threatened.
I’m not trying to bully this kid, if anything, he is bullying and threatening yandere dev. Judging from previous comments made by him (they are mostly threats and demands to make the game easier,scroll down to look for them), I already know that he’s a kid. No sensible adult would actually write stuff like “I WILL HACK YOUR COMPUTER!” or “MAKE THE GAME FREE OR I’LL DELETE IT!”. I am not trying to give this kid a hard time but his comments aren’t justifiable and are rather rude. I might be biased as I do respect yandere dev’s work but this kid should be giving criticism not blatant threats.
Ok, dude chill you’ve replied to this like 6 times now…
Oh, dude, why are you so rude? In my opinion MO is enough cool ’cause it makes gameplay more interesting…
I hope your comment was a joke… (and sorry for mistakes I’m just from Russia so i don’t know english very well ^.^)
Your english is accurate
Hello MC Shithead i just wanted to say that you are a Shithead and you should pobably play something for A LITTLE KID LIKE YOU ARE AND YOU SHOULD CHANGE YOUR NAME TO MC SHITHEAD
With anger Marko Plays
ARE YOU F*CKING SERIOUS RIGHT NOW STOP BULLYING HIM! BECAUSE HE’S ONLY A KID ALRIGHT?!!! HE MIGHT BE SUICIDAL! And you’re a f*cking b*tch if you ask me cause you’re the little brat here! 😄
Well it’s kind not our fault if he’s being a brat online and criticizing a game that a developer has been working on for many years and he’s trying to shit on it because he doesn’t approve of what the developer has done…
Sheesh bro calm down YandereDev can do what ever he wants to his game and if you don’t like what he does then leave.
I’m sorry, I accidentally sent you the above message.I wanted to send the message above to someone else.
Take care how you talk.
MC Master – Take care how you talk.
if you dont like raibaru just use an old build of yandere simulator that doesnt have raibaru
Yes I agree can people stop being rude to him?
Hey, kid, if your under 18 years old then you can’t play that game yet. So don’t watch it either. I don’t try to be rude, but you have to understand, so please, stoo, okay? 🙂
wow you think the game would be fun if he did that lol your such a hater and not to mention stupid
Lmao you’re like five are you even supposed to play yandere sim? Go play Minecraft kid.
NO THREATENING YANDERE DEV! I THINK RAIBARU IS A PROMISING FEATURE!
If your simply upset about Raibaru because she can stop you from easily winning the game, then your missing the point of the game. The point of Raibaru is to make the game what YandereDev wanted it to be – A stealth game. Her purpose is to make it hard, not easy. If you are really this upset then i don’t believe you are old enough to be playing this game, because it is aimed towards adult audiences. Not children.
Raburu is a girl…. and this game has been in development since 2014 when u have waited since 2014 for a game u can wait a few more months.
Can’t wait for SNAP!
Me too!
AND REALEASE OSANA WITH NO DEFENSE I WANT THIS GAME BE EASY OR ELSE…
Calm down, you spoiled baby.
ARE YOU CRAZY?You could just stab her in one second and the end????!!!!
If it isn’t a challenge then what’s the point?
Jesus dude, you should be grateful that Yandere Dev is putting a lot of money and work into Yandere Simulator. He makes the game more harder just so we don’t zoom Straight through the game and try to figure out what to do to Eliminate them. If you don’t appreciate Yandere Dev doing this then maybe you should play some other easy game.
just use the easter eggs you *beep* *beep* #newyansimfan
Shut the fuck up no one care about what you think
Or else what i dont think you can do anything behind that screen of you’rs you
Spoiled Brat
Can you f*cking stop this?? You know people can go to the older builds!
use PROPER grammar you 3 year old
Dude can you not? Yandere Dev has been working on this game for the longest time and many of us are proud of him. This is his choice, and I really think Raibaru makes the game more interesting, and tricky in a good way. Tbh It’s your fault if you can’t actually defeat a game 🙂
Yandere dev has said it in his old videos
it would be boring if there’s no obstacle to kill osana just by pressing that “F” attack button
he want us to use our brain and i think it would be fun if it’s a little challenging
and also there is a none deadly ending for confess to senpai it looks pretty easy
if you want to play the game so easy so bad then download osana mod without Raibaru (protective chan)
don’t be spoiled.
20 bucks says they’re trolling
WTF with the “indestructible rival”!
The teacher are pussys if Ayane upgrade her streng, but don’t mess with another students like the Student Council or the Rival’s Bodyguards.
I WILL KILL YOU OR hackking YOUR PC ALL
And I hope the same to you.<3
Dude chill. Threats won’t get you anywhere, it’s just showing how stupid you are.
weirdo
SHUT UP ALREADY YOU SHITHEAD
Oh no!!! Please don’t hack his devices! Then he’ll lose AAAAALL the progress on Yandere simulator
(Verdorbene Scheiße.)
We have to call FBI
And I hope you burn in hell where you belong:)
I take advantage that I arrived early to say: thank you very much, I LOVE YOU
Since there isn’t a lot of LGBTQ representation in Yandere Simulator, it would be really cool if Raibaru secretly had a crush on Osana.
It would give Yan-Chan someone to set up with Osana, and give more reason as to why Raibaru is so determined to apprehend Yan-Chan if Osana gets killed.
As a fellow lesbian I approve
Yeah that would so cool.
I approve of that
Not exactly! Since you’ll be able to have a female Senpai in the final game, her name will be Taeko instead of Taro. And if the stretch goal gets fulfilled, perhaps a Yandere-Kun! c:
Taeko: http://yanderesimulator.com/img/characters/senpai-chan-full.png
Yandere-Kun: http://yanderesimulator.com/img/characters/yandere-kun-bloody-full.png
That’d be so cool! Let’s be real, Raibaru and Osana would make a pretty cute couple, they’re already comfortable with and confide in each other (which is something Osana can’t seem to do with Senpai), and it would save YandereDev the effort of making a new character to be Osana’s suitor!
Yeah it would be cool but as Yandere dev has said before, coming out in high school isn’t very popular in high school and students tend to come out after high school. The LGBTQ+ community in Japan is still somewhat looked down upon but maybe Yan dev has a way around it. Whatever happens I fully support the ship anyway
That’s a really good idea! It would be so cool if he would put that in.
I love that idea! The shippening has begun!❤💛💚💙💜
Honestly, he has already spoken about LGBTQ representation in the game – specifically how in Japan, it is very rare for students to come out as such until after graduation! Though I agree it would be a wonderful idea, I wouldn’t get your hopes up due to his prior research of how it is in Japan. Unless you choose to make senpai female, it is likely that most (if not all) will remain either straight or showing no preference either way if it does not concern the gameplay. Having said that, choosing a female senpai will make all rivals bisexual and Yandere Chan otherwise lesbian!
That would actually be really interesting! It would add a lot more variety to the game!
High school students don’t come out in japan/ it isn’t spoken much He’s trying to make it as realistic as possible
*Corection
I can’t read porobalu so i read the first bit and assumed something don’t come at me pls
*Correction 2
i read a reply oops
I’m glad to finally know her identity! Her backstory and everything is amazing!
IF YOU DONT MAKE YAN SIM IS FREE I KILL YOU OR DELETE YOUR GAME
Ok… are you smart enough to do it…?
Because I reeeeeeaaaaally don´t think so!
Omg xD ur so awful
alright it’s confirmed that you are probably like 5, also i am sure yandere simulator will be free. and do you REALLY want this game to be easy? because then it will be boring and and a waste of time.
It IS free.
You are so stupid
you should know that you dont know hot to do either of those things
Can you f*cking this kid alone for once?!!!!
I’m pretty sure you’re the same kid using a different account. Your grammar proves it tbh. Can you stop making stupid comments just to try to defend yourself by pretending to be a different person (plus, no one pays attention to that)
do you know how to read?
I’m reading your comments. Just keep calm. It’s yanderedev’s game. He does whatever he wants.
911 whats your emergency
yes a spoiled kid is threating to kill someone over a game
ok whats the game
yandere simulator
ok we know his address we’re sending the cops over now
Only if you can use actual punctuation
You COULD delete the game, but there are something called backups.
@MC Master
Is your head ok? Calm down, kid.
lmao they game is confirmed to be payed people need money ya know?
Can’t wait
^^
Have you forgotten about snap mode or are you gonna archive it until after Osana?
Oops, sorry. I somehow skipped the last part
It is okki
ooooooffffff that’s a lot, but all of this is amazing
I KNOW HOW TO KILL RAIBARU
Keep up the good work Yandere Dev! You are doing amazing work!
Reblogged this on Ansatsunosuru and commented:
OOHH YEAAA HOPEFULLY JAY (AKA DAT DUDE) will make a video of this!!!
You made a lot of progress! I can’t wait to find a way to kill rival-Chan but osana will be the final target
This really makes the game more interesting.
I want to know if Ribaru will be the “guard” of all the rival, or just Osana
Just Osana
Other people will be bodyguards for others, like the delinquents to Osoro (they’re not invincible, but there may be other factors that make Osoro more difficult) and Hanako doesn’t need a body guard because Senpai in a way is invincible, and she’s almost always spending time with him.
YAASSSS I CANT WAIT FOR JAY (AKA DAT DUDE) TO MAKE A VID OF THIS!!!!
YEA SAME
Dude are you loving or hating i mean WTF
Prolly in a few months but HELL YEAH
OH MY GOD !!! This is really very unexpected!!! I apologize for the mistakes, I’m from Russia, but I want to Express my opinion about it. Cool thing is that there is very little left and we will see Osana in the game. I was scared when I saw “mysterious pripyatstvie.” Usually, the teacher (or someone else) just “wringing his hands” Ayano, but I THINK SHE BROKE HER ARM… It’s quite difficult to Express your opinion in another language, but I tried… I don’t know about you, but we in Russia thought that the “mysterious obstacle” would be info-Chan
First here to comment:
YandereDev can you please bring back the old font Futura Condensed Medium in Yandere Simulator…
im very greatful u started creating Osana and starting creating Raibaru i can’t wait see this aprehend scene
It’s usually things like these that make you wanna have a gun right?
I’m very happy that you made such progress in the MO, but I also have to say that I’m pretty disappointed in her appearance and her name.. to me, it looks like you didn’t put a lot of efforts for her to be a unique and well developped character…she’s the clone of Rival-chan, which I don’t really understand because she could have some matching accessories with Osana but without being her litteral former appearance, and her name is in my opinion completely unsearched…Raibaru…Rival…meh.. It just gives me the impression that MO is unfinished or muddled, and it’s sad because she’s supposed to be a very important character, not a random NPC or meme.
I absolutely love your game and love your work and it saddens me to write a disappointed message because I’m always happy of what you make for the game but this time I just feel like at least giving Raibaru another name, more researched than a simple japanese sounding transcription of “Rival” and giving her a more researched appearance would be so much better!
Nevermind, thank you anyway for your work, have a nice day Yanderedev! And sorry if my english is uncorrect or weird!
He’s had the idea for Raibaru and her looks for a long time, maybe since he changed Osana’s look. Plus in anime shows or anime games, the cute-looking characters have hidden strength, and it would be easy to doubt her and learn that she’s invincible. Maybe changing the name would be good but I dunno, he’s probably had the idea for her name for a while too.
Yeah I know but I didn’t mean that by her appearance, I’m talking about the fact that she has the exact same hair model, design since the beginning of the game, and I find it quite sad that she’s just Rival-chan, a meme, who was supposed to be Osana, she’s the litteral 1st appearance of Osana…I’m sorry I can’t explain it very well in English, I hope you get what I want to say!
Hey, may be I know how win against her, Budo won a fight against her so we can manipulate Budo to fight her again and kill her ? (sorry i’m bad in english ^^’)
not possible because you can’t manipulate someone to kill their crush of what I know
YES FINALLY I KNOWCTHE MYSTERIOUS OBSTACLE!!! I Really Didnt Think Rival Chan Would Be The Obstacle…
So awesome!
I do have a question. You posted a question of where is SNAP mode, but didn’t really answer it.
That’s okay edit it quickly!
I am a little confused though as to why we cannot have a build without Raibaru. I completely understand she’s pretty much nothing without Osana, but I would love to see her at least do more than she is right now. Her walking around is way more interesting than standing beside a tree. It would also be interesting if Budo or Senpai change their behaviour, like Budo blushes when is around her for example.
I also want to break Ayano’s arm more. I would say I’m pretty sick, but breaking an arm is pretty tame for this game.
YandereDev works day in and day out to create and develop this game. If it werent for him, This game would have never happened. And how dare you suggest that YandereDev should delete a brand new character thats currently being developed. And, Your just mad because once you play the game, It would be very hard for your little pea brain to get around Raibaru.
(Comment was for MC Master)))
So, the mystery of Budo’s crush has finally been solved
Great work Yan-dev and to be honest I haven’t actually played the game
Wait, would it be possible to match budo and raiburu together(cause budo got a crush on raiburu), so raiburu spends time with budo instead of osana? This could make it to where Osana is alone at certain points in the game.
Thank you so much for being so dedicated to the game’s development Yan-Dev! Honestly, seeing how much effort you put into the game and how much you like keeping us on our toes for the next feature to test out is inspiring to aspiring future game developers that may want to take the indie route! Keep up the great work, and rest if you need it! ❤
I’m sorry, if I’m wrong, but… Is that mean, that it will be possible to get rid of Osana by “friendship” with her? Just like with Kokona? I just noticed that itteraction between Osana and Ribaru are similar to Kokona and Saki… almost.
This makes Osana’s special rival for Ayano. Well, it’s funny, that I didn’t appreciate her earlier…
Good job, Dev! ^^
NOT EVEN IN MOTION CAN SHE BE STOPPED!
To be completely honest I think it’s too much to have the whole no talking thing, I can get ignoring music and I can get being hard to kill (though not indestructible, if Yan-Chan can kill budo then she should be able to win a minigame against Ribaru the same) but honestly what kind of person just completely tones out other people when walking beside their friend? What if she had toilet paper on her shoe?
Hello Yan-Dev i hope your game gets even more popular then now and that you be better and if you snezee bless you and of course Have a good day coming from a Serbian fan 😊
Yay, that happenned, finally. ❤
I think that to beat Raibaru, we will have to convince Budo to teach us martial arts, since he won Raibaru in the past.
Omg this is such a good idea
if bijuu mike see’s this
look for a comment by someone named
tresvsss they think they know how to beat raibaru
What’s the relationship between Senpai and Ribaru? (Dunno if I spelled that right) Since Osana and Senpai are friends, and Ribaru and Osana are really good friends, are Ribaru and Senpai friends?
Hey YandereDev! I have noticed something in YanSim…
The player can dismember the students, but when they are dismembered they have the school uniform on, even if they wore something different before that. For example the bullies, they have a shorter skirt and some other accessories, but they vanish if they get dismembered.
Hopefully that is necessary enough to you, keep going! ❤
If you could have at least three difficulties (like Normal, Expert and Professional) just like in Hitman, that would be great because not everyone is going to be able to beat the game that easily. YS is proving to be quite difficult at this point, with bullies, student councils, teachers, delinquents, witnesses, the mysterious obstacle and many more. I mean, I’ve played Hitman: Codename 47, Silent Assassin, Contracts and Blood Money yet this game is a whole lot harder than those games. I know it definitely isn’t easy to get away with murder, especially in a public setting like a prestigious high school but it’s a game!
i have an idea! She’s no umbrella right? Sooooo… that means we can burn her!!!
Or, according to her story, we can kidnap prisedent…. (THAT GUY WHO WON DEFEATED HER BACK THAN) and make him kill her!!!
Smart right?
i know a way to eliminate her put a bullet through her skull
I hope to someday own a PC or laptop compatible with YanSim so I can play the debug builds! As of now I only have a Chromebook so I cannot play it. You are an amazing developer Yandere Dev!
The name ‘Raibaru’ irks me somehow, I know its just “Rival” pronounced with a japanese accent, but the name doesn’t feel like it belongs to her… Maybe I’m just not used to it yet, after all, Rival-chan was really popular
I love how he inconspicuosly fails to mention SNAP. I love it when people do that (no sarcasm. I would like to learn).
Well now i’m super excited:) Your doing an amazing job YanDev:) Also sorry to hear you got sick
