May 16th, 19th, 20th, 21st, 24th, and 25th Bug Fixes

Last Update: May 25th 11:15 AM

The most recent build is located here:

I’ve got some bug fixes for you! But first, first, check out this cool artwork!

You can see a larger version here.

And you can find the talented artist, Aea, by clicking here.

With that out of the way, it’s time to tell you what bugs got squashed!

May 16th:

  • Limited the speed of the “Pass Time” feature and the speed-up debug controls so that it’s not possible (or at least not easy) to cause the game to run so fast that an NPC’s pathfinding breaks.
  • If an NPC is going to meet up with a friend and the player tries to talk to her, the NPC will politely explain that they are too busy to talk.
  • If two NPCs are having a private conversation and the player walks up to them, they will get annoyed with her and the conversation will end.

  1. Later on in the game it should be possible for gossip types or one that will correspond with popularity or braveness to have the option to take a picture of yandere-chan murdering a student or standing somewhere with evidence, just a suggestion.

    • Yandere Dev says that the “Gossip” type might not be implemented due to the fact of how hard it is to stop a student that just snaps a photo and runs — even though you could outrun her, but still. Yandere Dev also stated in an OLD blog post that — because he wants the game to have as many life-like features of a Japanese school as possible — he contacted a Japanese school-teacher, and the teacher said that students don’t usually have phones on them. As long as you’re a well-behaved student, you’re allowed to carry your phones with you.

      The feature could be added, but it has to be nerfed a little, due to the fact that it’s really on the “Hard” difficulty side πŸ˜›

  2. I know this is just a debugging version, but THANK YOU SO MUCH FOR PUTTING THIS UP. I’m having a hell of a fun time playing it, even with all the glitches and incompleteness. Killing all my fellow classmates as a Yandere is more fun than it should be. I will TOTALLY buy this once it’s complete and selling. AWESOME GAME

  3. After I got the May 20th Update, The game won’t let me go to class if I have a girl sedated and in the box in the gym storage room. I suspect this is because of the added feature where Yandere-Chan can’t go to class if a corpse is on school grounds, so I’m wondering of it’s registering sedated girls as such. Also, All the remaining students I had disappeared the following day after I made a girl commit “suicide” and they never came back even 2 days later lol

  4. Uh, senpai…?

    Senpai’s face and hair textures seem to be missing. This is from the most recent release.

    • A suggestion I thought of, and probably one you’ve already got planned, if having the Rival girls being special in some way. Like say, one girl is “The Head of the Kendo Team” and thus would be stronger and harder to deal with. Or a Computer Whiz who resists your attempts at cyber bullying easier (and can hack into your stuff!) but also has the added weakness of having a computer that you can steal.

  5. Having an issue where using wasd on menus for selection causes the a jump of 2-4 options, such as when selecting a subject in class the selection jumping from Biology to Physical Education with one tap of s. The arrow keys work as intended though

  6. the first time i played after download yan sim was fine but in the second time , it’s really hard for me to press “e” button to select and “w,a,s,d” to move yandere-chan , and when go to school , i just press 1 in 4 of “w,a,s,d” button , the day will end immediately , i can’t do anything . is there anyone who also had this problem , please tell me how to fix it cz i really wanna play yan sim . tks a lot

  7. Why not multiplayer sort of like Trouble in Terrorist Town but with like 3 Students trying to murder each other while trying to blend in with the innocents who need to stay alive?

  8. I killed a male student, dragged his body until it stopped bleeding, put the weapon and cloody clothes in theincinerator (without activating). I then asked a teacher’s pet to follow me and walked in such a way that he would HAVE to walk over the blood and body. He didn’t pay it any attention. I told him to stop following me, he walked BACK over the body and blood, so I tried to drag the body in front of him,but Senpai noticed it as he was by his usual tree.

    Not sure if people are meant to not notice blood and bodies lying around, as they used to at least notice bodies.

    • M’kay, so, I did it again, got three students to follow me, and they just walked over the blood and body, ignoring it; I then dragged the body for a teacher’s pet, who ran and got the teacher. I then burned the bloody clothes and knife I had already put into the incinerator. The Teacher then decided that it was a prank (despite the blood pools and body being quite blatantly left in the open…) But I still couldn’t go to class despite everyone being convinced that there was no body..

  9. I’m sorry, but can anybody tell me – how to change textures of Yandere-chan?
    No, I know how it doing, but when I did everything, the textures didn’t become activated. What I must to do with this problem?
    P.s. I didn’t touch JSON and XML.xlsm files.

    • Open the folder holding the data for Yandere Simulator, go to Streaming Assets, and there should be CustomHair, CustomFace, — and so on — templates. Just use a paint program like or Paint Tool Sai to edit them, then save them in Streaming Assets under the name of CustomHair — depending on what you’re customizing, like Face or Uniform — and MAKE SURE IT’S SAVED AS .png. It should work then.

  10. Hi YD! I have a suggestion. What about a locker for Yandere-chan? She could have new uniforms (to change to when being bloody) and Senpai collections, like pictures of him and such. Would be awesome! Keep up the great work πŸ™‚

    • That sounds like a fantastic idea to me, and I wholly support it. The clothes from your ‘associate’ could be placed in your locker. Plus then you have to get your clothes from your locker, without anyone seeing you wearing bloodstained clothes! And find somewhere to change too.

  11. YD had mentioned coming up with suggestions for different ways of kidnapping different girls.
    I had one idea while at work today.
    Have one of the girls interested in senpai be bisexual.
    Have the ability to have yandere chan woo said girl into coming over for a night of fun.(date or lewd acts)
    Only yandere chan has a different idea of “fun” for this evening.
    Just an Idea. If I come up with more I will definitely let you know.

    • How about a good ‘ol smash over the back of the head with a baseball bat and then take them home somehow?

      Sneak alcohol into a drink so they become drunk and then convince them to come home with you?

      Er.. maybe impersonate police, handcuff them and take them home? it could be an elaborate favour from your ‘associate’.. I think that might be a bit far fetched!

      Bad rumours, so a fellow classmate kidnaps them on your behalf?

      ..Its quite tricky actually… ><

  12. I know this may not be game related but would it be epic to have a song called WhenEver WhereEver by Shakira in the game lol it’s because the song is like a stalker song and would fit Yandere Chan XD do you guys agree?

  13. Hi ! First, i’ve noticed that you can’t have the new hairstyles in your bedroom. Also it seems like Yuno’s hairstyle as some bug, it still moves when you stop running. Also for no reason, when i left the bedroom i started on the rooftop, no idea why since i didn’t do anything special.

  14. A lot of people seem to have trouble telling the characters apart, in the future will you give characters things like freckles, different skin tones or make up to make it easier to tell them apart?

    • As the game progresses more and more, students will be customized more. Yandere Dev stated in an old post that they will have different skin tones, hair, eyes, etc. It all just depends on Yandere Dev. It might be someday in the future, not recent though.

    • That’s a decision for you to make. Personally, I will support the game itself, there are worse people (A lot worse and I have had the misfortune of meeting several of them). Addressing the criticism point, can everyone claim to take all constructive criticisms in a calm manner? Regarding the perversion points, I shall decline to comment, but looking at the game itself, what did you expect? Also, can deeklekgolo be trusted to be relaying 100% accurate information without embellishment? (again, a decision for you to make) but perhaps posting that on the dev’s blog isn’t the best move. No one appreciates that type of thing being brought up in what is in essence their own private domain.

      *having read some of the stuff in the links, personally, I feel deeklekgolo is placing some of his own bias in there, the text based links (the first three) don’t do much to support his argument in my opinion. But as I say, that is my opinion. It my be wrong, but as it stands with my level of information, I can’t say otherwise. You can decide for yourself.

    • Upon further research, I heard the thing with the grudge against the Skullgirls devs has passed over by now. YandereSimDev said it went different than he thought it did after re-reading the IRC log and he ended up letting it go, admitting the shame publicy. (I don’t have the screenshot on hand atm so take it with a grain of salt too if you want, it’s somewhere in one of the moe archives) So I don’t think it’s fair to judge him on that now.

      I also understand him wanting to escape the name in some ways and start clean. I think a good amount of us have wanted that because of stupid shit we did in the past.

      As for everything else, like John said, it’s up to you to make a judgement and up to you to decide if the only text responses are real or not.

  15. Regarding the new student, her computer is always on, regardless of if she’s using it or not. Also, I stood off to the left of it, at a 45 degree angle from the front of it, and the new student promptly span on the spot.

    And the ‘old’ students. When leaving the school at the end of the day, they all aim for the smaller gate (which is closed) This causes them to bunch up, walk in a small circle, then one darts out through the gate, then they walk in a small circle again.

    When reaching level 2 language and biology, only the level two biology message is displayed. Also, not sure if there is meant to be a level 2 chemistry message either, but there isn’t one displayed for that.

    Aside from that, looking good! ^^ I’ll try to see if the level 2 subject messages display individually later.

  16. I think I found a bug in the latest build (May 24th). I pushed the purple-haired girl off the roof after school at around 4. The sound of being seen triggered, although no one was there with me. After pushing her, immediately a teacher spoke like she had been led to a corpse by a teacher’s pet, but when I looked where the corpse should be, there was no teacher or body or blood. The game prompted me to clean up my mess before the cops arrived, but with everything except ‘body’ already checked. Since there was no body to be found, I went home. Her death was ruled a suicide by police. Also, her shoes were floating in mid-air off the railing.

  17. I noticed the Teachers were ignoring corpses male students were leading them to until i started dragging them. Is this fixed in the May24th version?

    • It should be based on the notes. Maybe give it a try and let YD know the results? I did notice that issue in the last build. Haven’t tried it yet though..

      • I’ve checked it, the voice plays twice in succession; the first time they ignore it, then on the repeat, they notice it and call the police.

        They don’t notice a lone bloody footprint or Yandere-Chan holding a mop with some blood on it though! ^^

    • You could literally have blood soaking the entire school grounds and the teachers would not notice. This isn’t a bug, it’s just showing how Yandere Dev hasn’t had time yet to fix such mishaps. — Patience.

  18. Well, found things with 24th may update.
    1. Language skills level 2 isn’t showed when you add enough points. You can’t leave the suicide either.

    2. Sometimes Pippi is acting strange… She is going on the rooftop and …freeze. As well as she is staing at the lockers till the end of the game.

  19. I was in Hateful Mode and ran after a teacher with a katana and when I attempted to Attack (not sure if I was successful) she turned and got me like normal…but was running in place XD


  20. when playing the latest build after if i choose to poison food and then go to class the game gets stuck on the all white screen.

      • ah sorry for the confusion as far as i know i only picked up the poison from the cabinet at frist i thought that i had poisioned like a stored lunch box but then i relised what it was. if anyone else knows how to posion food or if thats a option yet i’m all ears lol

      • It’s most likely going to be in the next update — seeing how Yandere Dev already implemented the poison. You can’t poison food “OFFICIALLY,” because the feature isn’t fully yet developed, but in the next build — possibly — it will be possible to poison food.

  21. I was playing Yandere Sim this morning and it would not let me go to class or go home. I put it on Yandere for the display whatever. I can not know if it was because of that.

  22. Thank you so much for putting debug builds like this! Even though it’s not even technically a demo, I am having a ton of fun with play testing this!

    I’m extremely excited about watching the development of the game as it progresses and when it will be finally released! Thanks for all of this, and don’t ever stop posting this kind of stuff!

  23. Attempting to increase Yandere-chan’s bust size while in hatred mode is a bit broken. They expand, but they turn into flat pancakes instead.

  24. feature suggestion: you should let yandere-chan put a secret admirer note in senpai’s locker, or get one of the other student to deliver it to him.

  25. so i killed senpai.

    as expected, the game basically froze with yandere-chan in her dere-mode and while i could teleport and stuff, i couldn’t move. got stuck waiting until the police showed up and arrested me. apparently if you run after him when he’s spotted a dead body, he gets an attack prompt like everyone else.

    not a glitch report or anything, just thought it was interesting!

    • How did this happen exactly? I keep trying to successfully pull it off and the prompt shows up for me too, but…

      • Well, what do you know? I managed to replicate it after some fiddling around. It needs good timing after Senpai starts running.

        What a Yan image.

      • Managed to get the weapon I used to kill him just riiiiiight before the field where Yandere-chan goes into dokidoki mode. Burned it and the uniform. Students came down and found his corpse eventually but no one reacted to it and they all just left the school. Got the police report like usual and moved on to the next day (I was expecting a crash honestly), aaaaand… the classmates didn’t come back.

        Yandere-chan goes into dokidoki mode right at the middle door at the entrance of the school. It seems Senpai’s ghost still lingers here. His death must have messed up the whole universe and caused a paradox. Now Yandere-chan is stuck in endless school hell with no one except the teachers until reset. Or she can be happy knowing no one will get him now and that he’s waiting for her in the ‘afterlife’ somewhere…

        What a thrilling story.

  26. You should add the option to drown a girl in the pool, but, like the fake suicide (chainlink fences) they would have lifeguards.

  27. ok so ive been out for 2 days 2 DAYS!!!
    and theres been a update of a new girl
    a chemistry class
    and poisin
    ummmm what
    please some one update me on everything wheres the poisin how do I use what
    im confused
    glad haahaha thxx

    • Poison is located in the chemistry lab — second floor, to the left, door on the left — and it’s not fully usable yet. The Poison Food feature isn’t fully developed NOW, so you can’t really “use” it as of now. Soon, though.

  28. XDXDXD one of the most funny indi game who i found, i have a suggestion:

    1.Why not a Yuri ver?, they are lots of peoples who like the yuri storys and be cool have a gore yuri game, and i think to this make the game more fun, this ideas can be help:
    1.1 Posible choice a female or male sempais.
    1.2 So choice a female sempai, mans and womans try to confess to her and you killed the boths, giving the game more difficult.
    1.3 Try to convince the female sempai to choice you via interactions and conversation, or kidanped her.
    1.4 So she dont accept you, blackmalied her using the photos who you take.

    • Yandere Dev stated that a female Senpai will be implemented into the game in the future. It’s unsure if he might use the features stated.

  29. I’m really sorry to be another asshole making suggestions, but:

    One thing I always love with yandere stories is when they do increasingly disturbing secret things to their love interest. You’ve covered some of that with the idea of the “shrine”, but it there could potentially be other things like slipping some of your blood into their food, etc

    • YD uploads the latest build when a new one is created, the download link is at the top of this page. It doesn’t update automatically or anything.

  30. So some glitches I came across:

    1. The stairs in the gym, the ones behind the stage that lead up to those windows in the back are easily clip through-able, leading me to fall off the stairs but just be on the floor…like an Escher painting! Then the windows can also be clipped through.
    2. You know it already, but the Xbox commands come up with a keyboard still.
    3. Yandere isn’t standing on the roof but clipping through enough where her loafers’ heels are sunken into the floor. When you crouch or kneel she also does this.

    I also thought of some other cool killing tactics/additions to the game:

    1. Maybe have it so the stage has sandbags and pulleys in the back, so like, you tell someone to follow you and when they’re not looking you cut/untie a rope and suddenly a set piece falls on her and kills her? It can look like an accident by untieing the knot that held the sandbag keeping the set in the fly’s.
    2. Act out a scene from a play (Like M@cbeth [not taking any chances #theatremajor]) where Yandere-chan has to stab her co-actor, but instead of the fake knife she uses a real one. If she disposes of the fake knife or maybe plants it on another student, it would look like either the other student switched the knife or maybe it was an honest mistake.
    3. If there is a general science class, then maybe have it so after school one day, Yandere-chan can modify one of the computers so when it’s touched, it shocks someone to death. Most people would write it off as a faulty product if she does it well enough.
    4. After school study sessions to get extra study points? Like, Yandere-chan instead of killing someone can stay after school with a teacher and add bonus study points at the expense of time possibly spent killing a rival.

  31. If you don’t mind I would like to make a page of Yandere Simulator on facebook
    I have friends that own a really good pages so we can help with publisityy
    if that’s ok
    ill link the page beloow okk.

  32. if senpai sees a corpse (this is from may 25th) you can attack him. i recreated this bug three times in a row so i know it’s not random…. (he mustn’t notice you, he simply has to see a corpse, when he is frightened you don’t get nervous and you can attack him, however when he is dead you get nervous and can’t drag him or he weapon you drop…..

  33. Hello, good work on the game. I’m a big fan.

    I’ve got some ideas which could be inplemented, and found a little bug.

    FIrst off, about the bucket of water you’re using to clean the blood.
    What if you had to fill and empty it at a water supply point, like, near a stadium? Any studient seeing you with the red-colored bucket would get suspicious and you would have to lie or kill them to avoid getting caught. Also being part of the art club would make you less suspicious since you’d be able to say that it’s a bucket to clean the painting tools.

    The other idea i’ve got is, the teachers start doing body searches at the school gates and sometimes randomly inside the school. And as the tension inside the school climbs, the teachers do these more often, and begin to ask all students to give their sharp tools to keep them in a dedicated cabinet (metallic rulers, scissors, compasses, etc..). The key for it could be stolen with heavy difficulty.

    Finally, about the poison.
    I don’t know what’s planned but since there’s no cafeteria it could be interessting to put one. You would also be able to poison your rival’s bento or offer him a poisonned drink or food that you would have to prepare beforehand.

    Then the “bug” report.
    When you fake a suicide and then move the corpse, the text at the end of the day changes but it doesn’t fit with what happened. They talk about “not being able to find the weapon”.

    That’s all for me, I may be offering my services for a french translation when you’ll need it.
    Waiting eagerly for your next update ! πŸ™‚

    • I forgot to mention it, but it seemed obvious to me that the water gets redder as you dip your broom in it. πŸ™‚

    • There will not be a cafeteria in the game. As Yandere Dev said in an older post, he wants the game to be as life-like as possible, kind of like a “Slice of Life anime.” In Japanese schools, there are no cafeterias. Students must find a place to eat — their own lunches or lunches bought from stands inside the school, set up by local bakeries/restaurants, etc. — where they won’t be in the way of anyone. For example, the roof. It’s an interesting idea to be able to offer rivals/witnesses poisoned foods or drinks. It was already said that Yandere Dev would implement poisoned food — like bento boxes — in a future update/build.

      • I have a few questions on certains points πŸ˜›

        I there anything planned with the council student ? There could be some patrols in the school buildings and fields, and/or a rival who’d be a popular and influent member, always accompanied by a few students. And maybe Yandere-chan, with an astounding popularity, could become member, and even prez. (who knows..)

        Also, i’m wondering if there’s gonna be class representatives that you could more hardly manipulate but with more possibilities than just your typical student ?
