This update isn’t too special; I just wanted to upload a new build to reassure you that I’m still actively working on the game and making steady progress every day.
But, depending on how things go, the next build could be a lot more interesting!
- There were always meant to be 10 Headmaster cassette tapes, but putting lore tapes into the game hasn’t been a high priority for a long time, so I neglected that feature for the past several years. Recently, I had a power outage for a few hours, during which I wasn’t able to get any work done on the game. So, I used that time to write the last remaining Headmaster tapes! The Headmaster’s voice actor has recorded the tapes, and I’m almost ready to put them into the game; I’m just waiting for an audio engineer volunteer to apply an “old-timey cassette tape” effect onto the recordings.
- The “Yandere-chan and Info-chan meet for the first time” text message conversation was written back in 2015, and is some of the oldest content in the game. I feel like the writing was pretty rough, and that I could have worded things much better. I also feel like there is some important gameplay information that needs to be imparted to the player (panty shots aren’t the only way to earn favors from Info-chan). With these things in mind, I decided to re-write that conversation. The voice actresses finished recording it recently, so the next update will most likely contain an updated Yandere/Info conversation!
- Ever since I first implemented the Student Council girls, I’ve wanted each of them to have voice acting…but it was difficult to locate the ideal voice actresses for the job. Recently, I decided on the actresses who I believe would be perfect for the Student Council girls, and the plan is for them to record very soon! Depending on their availability, the next build may finally contain voiced lines for the Student Council girls!
- For the past 5 years, Yandere Simulator’s school hallways have been empty and devoid of props and decorations. It was never meant to be that way; the hallways were always meant to have props, but there were always higher priorities than aesthetics and decorations. At this point in time, though, we’ve finally reached the stage of development where there is practically nothing left to be done, and I have recently received a ton of appropriate props for the hallways, so it’s possible that the next update will finally contain fully-decorated hallways!
- There is only one more “lore” tidbit that I want to be included in the Osana demo. After it goes into the game, there will be no remaining “lore” items taking any of my time away from Osana. I have the necessary models and voice acting for it, so it’s possible that you may see it in the next update!
By the time I release the next update, it’s likely that I will have finished all Osana-centric tasks. After I hit that milestone, the last remaining task will be to give the game a fresh coat of paint (new UI, new HUD, new title screen) before releasing Osana. I want the new graphics to be a complete surprise, which means that once I begin working on the new graphics, I won’t be releasing any more builds until Osana is complete.
In short, what I’m saying is that, after the next update, there may not be any further updates until Osana is finished. It’s not a 100% guarantee, but there’s a strong possibility that this will be the case. (If critical bugs are discovered, I may need to release bug-fixing updates or something.)
Anyway! To see a list of everything that was fixed/changed in the latest build, scroll down past this gorgeous artwork of Prealle!

Fixes, Changes, Additions
- When I upgraded to Unity 2019, Unity defaulted to producing 64-bit executables, meaning that the game stopped being compatible with 32-bit systems. I recently tried to produce a build that would be playable on 32-bit systems, but when I tested it, I encountered a bunch of crash bugs, so I had to revert back 64-bit. Unfortunately, Yandere Simulator may be restricted to 64-bit systems for the forseeable future.
- If a teacher (or student council member) sends Yandere-chan to the guidance counselor for carrying a weapon, the weapon will be taken away and put inside of a box in the faculty room. As of now, if Yandere-chan is spotted carrying a fire extinguisher, the fire extinguisher will now be returned to its original position instead of the box in the faculty room. For now, fire extinguishers are (deliberately) the only exception.
- Prior to this build, if the player joined a club, the game would remember what club the player joined, even if the player reset the day, got a game over, or loaded an earlier save immediately after joining the club. As of now, the game will not carry the player’s club status forward to subsequent days unless the player successfully makes it to the end of the day.
- Removed exploit that would allow the player to get an easy panty shot by getting so close to a student that they were clipping inside of the student’s body, then pulling out their camera, inserting it inside the student’s torso, and aiming the camera straight downwards at their panties.
- Fixed bug that would cause the “follower countdown timer” to remain above the head of a student who was previously following Yandere-chan, if the player attempted to splash them with water twice within one day.
- Fixed bug that would prevent the player from being able to use the “Find Student Locker” feature if the player had placed a note into a student’s locker earlier in the day, and then killed that student.
- Prior to this build, a bloody weapon would not be considered “suspicious” if the weapon itself was a non-suspicious object (such as a screwdriver). This oversight has been corrected.
- Prior to this build, the act of using a handheld blowtorch to cauterize a corpse’s wounds was not considered to be suspicious behavior. This oversight has now been corrected.
- Fixed bug that would allow Yandere-chan to take a shower while standing outside of a shower stall if she activated the shower prompt while standing in just the right spot.
- It is no longer possible to sit on the bench where Sakyu / Inkyu have their daily conversations, during the point in time when they are meant to have a conversation there.
- If a Teacher’s Pet runs to the faculty room to report a murder to a teacher and discovers that all 6 teachers are dead, they will run out of school instead.
- Obtaining the “Genocide Ending” will now result in dark, creepy music playing during the game’s credits, instead of the normal credits music.
- Fixed bug that would cause the laughing feature to become broken if the player was mashing the laugh button while loading a save file.
- Fixed bug that would cause a phoneless’ student’s phone to magically re-appear in their hand if they heard Yandere-chan giggle.
- Fixed bug that would cause the map to perpetually move if the player was holding down a movement key while summoning the map.
- Fixed bug that would prevent students from being able to notice Yandere-chan if she was aiming her camera while crawling.
- Wielding the drama club props will no longer be considered suspicious if Yandere-chan is a member of the drama club.
- The grass in front of the school will no longer fail to change colors properly when lighting/atmosphere changes.
- Fixed bug that would cause Midori to perform a “texting on phone” animation while searching for her lost phone.
- Saving/Loading will now properly track how many blood pools were at school, and where they were located.
- Saving/Loading will now properly track the locations of all buckets/mops/bleach containers at school.
- Saving/Loading will now properly track the contents of all buckets containers at school.
- Saving/Loading will now properly track how much blood a corpse has spilled.
- Various code optimizations to make progress towards improving framerate. (Previously, I was at 47~52 FPS, but now I’m at 52~57 FPS!)

Wow! So cool this update,continues making progress YandereDev,I can’t wait to see Osana in the future,good job!
i love yandere dev this build might be amazing i will always yandere sim ur so close
Sweeeeeeeeeeeeeet, I’m excited for Osana 🙂
I updated the page and … BOM!
Yandere Dev has updated the game!
THANK YOU YANDERE DEV! I LOVE YOU!
Good Job Yanderedev
I’m so excited and amazed how the game changed, I remember how all the club rooms were empty and Kokona… I’m feeling so much nostalgia. Thank you Yandere Dev for improving the game. Can’t wait for Osana and to think that after so much time she’s going to be finally in the game I’m just so excited! Keep up the good work!!! ❤️
Oh dang, cool! This sounds really promising.
Whoa! I really wanted to hear the Student Council voices lines! I’m so excited!! This sounds promising!! Good job YanDev! We’re suporting you no mather what will happen!! 🤗🌸
Matter* 😅😂
me too ı dont want wait until june 😦
I’m really excited for the new update! 😀
I can’t wait! Take all the time you need, I’m so excited!! Good work!
Osana will definitely come out this year. Plus even if she won’t be in the game yet,at least we get at least one medium update per month so it is ok. Plus if Yandere Dev has more ideas for the final game, I personally have no problem with that.
Sorry if this message sounded rude.
It looks like somebody delete his/her comment. So yeah…just ignore what I said😅😅😅
This is so exciting!
What are you on about he never said anything about 3 months he said there’d be one more update mabye a bug fixing build the Osana so please stop pulling numbers outta your ass ya
Ignore this someone was being rude but looks like there comments gone
So excited final stretch baby 😃 good job yandere dev you’ve worked so hard for years on this game and it’s all starting to finally come together
(I also hope the new building will be designed like the storage rooms and yan chans basement because I really liked the design 😋😊)
Hey YanDev. I was playing this build and when I’m holding a prop from drama club is saying that I’m visibly armed even if I joined the club. I hope you see this,have a good day! 🌸
same
Same
Hm, it might just be a small bug.
Technically, it is true that you’re visibly armed but the students won’t say anything because you’re in the drama club.
They are saying that “That is a prop from drama club? It is for a play or something?” or something like that. I don’t remember very well.😂
Hey yandere dev when i try to download the Unity 2019 Build with the link instead of the lancher it doesn’t work And if i did every girl (including yan chan) was disfigured i dont know how to send a picture.
If you mean disfigured as in only floating hair, teeth, and underwear, then it’s a known issue. The female material, for some reason, requires Shader Model 5.0, so 8+ year old Intel graphics devices (earlier than 2012) and 10+ year old AMD/NVIDIA graphics devices (earlier than 2010) will not draw it correctly. We are still hoping to create a fallback for older graphics devices, although no promises.
thanks!!
thanks for the help!
OMG I’m so excited to see new props in hallways, voicelines for Student counciland new conversation lines in Ayano’s and Info Chan’s dialogue!!!!!! AND GOD DAMN I WANT TO SEE NEW TEXTURES AND GRAPHICS!!! I adore updates!
I am really happy that you are working on things that was at the back of your mind. And I also have been wondering why the student council girls have no unique voice despite being very special characters.
And I have a feeling that after releasing one more build. You will change the graphics and animations. This could take months……
But I will wait…..
Also one question:
Are you going to add anymore students. You said you wanted 88 students int the school. But you only have 77. Just wondering…..
Have a good day yandere dev…..😊😊😊
He has some spaces reserved for rivals. 10 spaces for rivals, a few for mysterious obsticles(I think) and other students.
Oh my gosh, where is Osana… 😱😱☹️☹️
We need to be patient
IM SOOO EXCITED TO PLAY THE NEW BUILD!!!’
I just have one tiny question…
When you ask a student to follow you and the timer appears for let’s say a minute. When the timer stops and you ask them again to follow you, shouldn’t the timer be a lower number like 45 seconds? Otherwise it’s pretty worthless and just comes out as annoying to continuely ask them to follow you if they just follow you for the same amount of time. (If that makes sense at all).
Oh, Yandere-Dev you tease. Stopping us just as the next big update is right there.
Though to be fair, the power outage might’ve just been at the perfect time to finalize the dialogue since it’s one of the most time consuming and unreliable thing to wait for next to models.
not sure if this is still happening, but when will the PE part of the day be added? i’m pretty sure yandev said at some point that was a planned feature but i’m not certain
Hm, after Osana probably!
Next bug BZT-
I think you mean “ Necks 🐞 BZZZT” 😂
So anyone been on Twitter lately?
okay, first of all yandere dev. you are making so much progress!! but the school model just doesn’t look… fitting. i feel like the game would be so much better if the schools forts are bigger so the students won’t have to walk in a big kanga line.
if you look up “ Yandere simulator mission school mod” it shows a mod of a beautiful school that looks so good.
if you used that school and took out of a few room or spaces that are not needed the game would be perfect!
i like that idea, but i feel like we’re so used to the current school, lots of ppl wouldn’t like that
Every day the game gets closer and closer!!
I’m really looking forward to discovering all the lore in the next build:D Personally, I don’t care about the UI and stuff like that, but I know it’s important to you, since you want the demo to feel different from what we’ve been playing until now. I just hope it doesn’t take too long, as I am practically salivating at finally getting to play the demo and try all the special eliminations on Osana; like matchmaking, rejection, gossip, befriend/betray, framing, maybe kidnapping Raibaru and have her murder Osana or the other way around. God, I’m gonna have so much fun with the demo once it’s ready
wait so because the student council will have voices in the next update, does that mean they’re gonna have their own tasks? and if so, does that mean we’re gonna be able to join the student council?
Perhaps….
So is it not okay to add silhouette students in the background of Yandere Chan’s view and maybe have them fade away little by little when the atmosphere of the school becomes low? I don’t know if this idea has already been said 😕
I also thought it would be cool if the credits of the genocide ending to have bloody petals falling down!
Sounds evvviiillllll >:3
very >:3
I am so excited!! I’ve been following this game for a few years now, and it’s so great to see so much progress being done! I can’t wait to murder people in cold bl- uh-h-huh? *Smiles innocently*
Hello Yanderedev, I became Midori number 2.
I have a lot of questions about game development.
Could you answer it please.
I can see that you haven’t watched the forty minute long video on his YouTube channel explaining people like you🖕😛 You clearly don’t understand that one person, that still should take time to focus on himself, is creating a highly ambitious project that takes multiple years. He even said that he shouldn’t have put so much emphasis on Osana because he didn’t want his audience to think that she was his main priority, and he wanted the game to be absolutely polished u til he started making sufficient progress on her. So please, before you post a nasty opinion that no one asked for and that has already been talked about in previous videos, maybe consider being patient for something that is going to break records, even if it comes out in a decade from now😋
Why are you being rude? As I see your mother didn’t teach you manners little one? Let me explain, a game is made in such a precise way to swing its ideas, the key elements of the game, core game mechanics, etc… However the problem with Yandere Dev is that he doesn’t organize his ideas, which handicaps the development of the game. Instead of taking responsibility for his mistakes, he makes videos that aim to manipulate brats like you, if you see what I mean. So being called “people like you” by you is really very flattering, I’d rather be called a jerk by a stupid person, than intelligent by someone like you. This shows that we do not have the same reasoning at all. Otherwise Yandere Dev develops a game and collects a salary at the end of the month (donations), he even said it himself. Prioritizing futile things and caring more about yourself is a great lack of respect, but you don’t know the right manners and logic in itself, you couldn’t understand ❤️♚😍
Hey. Yanderedev.. what about the new characters model?????????????
Might be included in the polishing of the game or after Osana!
Alright, More Lore. I can’t wait for the next build to come out
Hey!!! Take it easy… YandereDev is traying his best. You don’t need to be so rude with him
I’m sorry but we’re not ducks, nor pigeons. He didn’t even make a single progress in two weeks, knowing the fact that he had to release Osana or at least improved the game’s aspect this month. He received in total more than $60000, in six years and he has the audacity to complain. The thing that I hate the most is that he keeps dreaming about some sort of strange scenarios on reddit and keep answering fans’ mail. We aren’t pigeons or ducks. He gain a lot of money but not even deserve it. I don’t care about all the drama related to him, I don’t give a damn about who tf he is, we didn’t give him money for that. We gave/give you money because he is the developer of Yandere Simulator, and that’s it. The only thing we want from him is to work on his game, we’re not asking more. All the YanSim’s drama happened to him because of his lack of skills
We are getting so fuck_ng close 😆😆😆. It’s crazy to think that the first time that my friend talked to me about YandereSim i said “i don’t know dude… That doesn’t sounds very funny” and now i can’t be a single day without playing the game. THANK YOU YandereDev for this master piece 🙏🙏🙏
K, but I actually find it hilarious that you sensor the i in f***ing rather than the uck XD. (Sorry, know this is random but it made me smile) Also, I KNOW RIGHT?!?!?!?!!!!!!!!
Ohhh!!! I have a question, this might be a spoiler but i really want yo know. How many differents endings are you planing for the final game ?
There’s a little mistake but you know what i mean
15 at the very Least. It depends on 25 factors.
Which Rival was eliminated in which method (10)
Did the Player collect All of each tapes? (4)
Senpai’s sanity (1)
Info-chan’s relationship with Ayano (1)
How many people are still alive in the Game (1)
How many people are inside ayano’s basement (1)
Ayano’s reputation (1)
Etc
I can’t remember them All
My personal hope is that the endings will be on a sliding scale from very sweet and wholesome to utterly dark and disturbing. Like, the most wholesome ending would come out of matchmaking all your rivals and never doing any yandere actions, and then when you confess to Senpai, he will accept and be so happy that there’s actually a girl who loves him (if matchmaking is the most used elimination method, Senpai will begin to worry that there’s something wrong with him and that he’s not as appealing as other boys), and an example of a dark ending would be one where Senpai was witness to the rivals deaths (like poisoning Osana), and has just become a broken shell.
Why it’s quite nice to comment on this blog or website I am quite excited to play your game but I am going to wait till your game is fully done. Yet quite excited. ❤️
Wow! Everything seems to be so close to the final stage of Sandbox! Is really promising to see everything this, and the next build will have
Wish you the best of lucks
Mate, fixing bugs is not making progress? You would like to play a game like this, but filled with things that would really make the experience awful? No one likes a game without polishing at least a bit, and trying to renew really old aspects of the game is because of that, making the experience better, that’s why he has taken so long to make this game, and in the last bit of development all we can do is just, like we already did 6 years, wait.
Maybe you should take in care another point of view, or putting yourself in place on YanDev, it will make seeing everything clearer
Don’t waste your time explaning this to that guy. If hi is not happy with the development of Yandere Simulator he should get out of this blog and don’t bother….
So I know this isn’t really that important to the game (or maybe it is?), I had a thought of having a transgender student at Academi High aka Akemi Himari (I actually looked that the most popular boys and girls names and thought, hey if they are transgender maybe they could have a boy and a girls name? You could also switch up the order and make the name Himari Akemi, its not my decision, maybe they could be a childhood friend of Taro?) This might add another level to the game, like if you befriend her/him/they you could get info about Taro’s intrest’s (One of course being reading) but like maybe they could tell you what books he likes? Then Yan-Chan can maybe buy it from a book/manga store know more about it and have even more of a connection to Taro? This could be a fat game changer considering that they would know stuff about Taro that even Info-Chan doesn’t know (Weird, something Info-Chan doesn’t know? Strange) Maybe they wouldn’t appear in the first week considering Osana is a childhood friend of Taro and that might get annoying, who know’s? This could help Yan-Chan a lot. Maybe they could be a bit more of a guide in an easier mode and just a regular student in other modes? Maybe in a hard mode they could be hesitant to want to know you after they seen Yan-Chan get flustered by Taro, that would take some persuasion to get them to be friends with you? Possibly performing yandere action’s and AH/HA (Their initials maybe) would damage her image to Taro, it would quite fun and make the game harder, maybe. Or a completely different path would be that they have a crush on Yan-Chan making it harder cause they would follow when they weren’t doing anything also making it harder to get away with, “things” and maybe you could matchmake them with someone else who likes them? Or would that be too much like what you with the rivals? A completely different subject, if Yan-Chan knows things that Taro likes she can get her numbness up to help her stop getting flustered by Taro and can build a relationship with Taro? Maybe this cant be done because it would trace away from the real plot or maybe not. Possibly getting numbness up you need to do things that would take people a while to figure out for themselves and it would add a challenge to it? This was a really long comment, the thought popped into my head randomly so I thought I would type it out as soon as possible. Congrats for actually reading all this comment, stay safe. Peace.
That’s a pretty good idea.
I think you are right. If Taro is the only reason for Ayano to Live, it would be more logical if she wants to know everything about him, i mean ¡EVERYTHING! That would make the game more difficult and interesting. It’s necesary make emphasis in the rivals but Sempai plays an important paper in the game
I’m quite excited to see the whole story line of Yandere simulator. I can see that you’ve put a lot of thought into the game and a lot of creativity, plus all the effort!
Why didn’t I receive an E-mail……But we are so close to having Osana in this game ! UwU ! Im excited 🙂
Stop. It.
Just to know there was a person that… I was just replying to that person and I think they deleted the comment? Sorry for sounding rude : /
Dude! Were so close to the demo. It’s been 6 years of development, but I think it was worth it! Look at Akademi High now and how it used to be in 2014 builds!!! I’m super excited! I use Lovesick part of Yandere Simulator at night, DUDE IT’S SO CREEPY XDDDD and all the challenges are awesome! But hey, I have a few ideas to be added into the game
1) the Check components option: this option checks your PC specs and picks the best graphics options to get at least 30 FPS by reducing or fully removing physics, and more!
2) the Unstable version mode, where you type at the main menu “yanderedev” and you will get the experimental version of the game (Osana in the game, the latest work YandereDev did to the game) and you could help YandereDev by submitting bug reports before releasing the official demo
What do you think?
I found A bug : when the sports club run on the field they are so slowy
I think it’s just their speed; but if they are going extremely slow, it may be a bug.
Yes !!!!! I NEED THE VOICES !!!
The Student council girls are my favorite characters, it’d be super cool to hear their voices !!!!
And I’m also curious about the tapes ! I’ve wanted to hear more about the Headmaster for a long time !
Thank you, Yandere Dev ! You just raised the hype to a high level in one post !
I think it would be better if the bad ending’s font color should be red and the background of the bad ending credits should show a dark bloody scary hallway with bunch of dead bodies and glitch effects since its a genocide ending. And the good ending credits should show the cherry tree behind the school with a bright sunset with the “Star-crossed lovers” theme song playing
It sounds quite awesome!
This is actually fantastic! I’m really dazzled and excited for the next update!!
Keep up the great work YanDev!
Hey yanderedev! I just wanna share the most nostalgic moments I had with the game that made it really funny and thrilling af. It was those times when I can still try to run away when teachers or delinquents try to chase me but it’s all for naught and get a jumpscare every time the teacher caught you cuz they fast af. It was scary but was soo funny when I watched others experience it as well especially when jay plays it that was always the heart racing part. Dunno just miss those times. I know it will never be back because of bugs but it was a good experience.
I miss those too. Yandere ghost adventures was probably One of my favorites. Jay and the NurseBooty having Netflix and chill
