June 15th Update

Over the past two weeks, a very large number of bugs reports were submitted. I fixed every bug as the reports rolled in, and by the time two weeks had passed, the game had accumulated over 70 fixes and improvements! I’m pretty sure that this build represents the biggest difference between two builds in Yandere Simulator’s history!

Although I was planning to not release any more builds until Osana was finished, the current build of the game is such a massive improvement over the previous one that I can’t help but release a new update. For the longest changelog I’ve ever posted, scroll down past this striking artwork by DeadlySicretOfAchlys!

Long Weapon Rebalancing

Short weapons (like knives) can be concealed, so that the player can transport weapons in secrecy. However, long weapons (like baseball bats) cannot be concealed. For years, this meant that long weapons were objectively inferior to short weapons, and that there was no reason to use long weapons.

To give the player incentive to use more than one weapon type, long weapons were given an advantage; victims killed by a long weapon would not leave blood pools. However, this made long weapons too overpowered; it removed all incentive to use short weapons.

To balance the advantages/disadvantages of both weapon times, non-concealable weapons are now 5x more suspicious than concealable weapons; this means that students will notice you carrying long weapons and become alarmed 5x as quickly. This means that the player needs to be very careful and stealthy when carrying around a long weapon, or else their reputation will get annihilated quickly.


  • In Japan, you have to be at least 20 years old in order to purchase alcohol or cigarettes. Yandere Simulator takes place in a fictional version of Japan where you need to be at least 20 years old to purchase pornography, too. This is why Yandere-chan needs a fake ID, despite being 18. To reflect this, the “18+” in the stores has been updated to say “20+”.
  • The player is no longer able to save the game under circumstances that would instantly screw the player upon reloading the save file, or circumstances that would be very difficult for the game to re-create. A message will appear on the pause screen menu when saving the game is not possible.
  • To make it possible to complete a Multi-Mission that involves poisoning more than 2 characters, it is now possible to purchase infinite Lethal Poisons from Info-chan, but only during Mission Mode. (Lethal Poison is also now less expensive in Mission Mode.)
  • Saving/Loading now tracks kidnap victims, whether or not there should be a fence on the roof, the school’s current level of atmosphere, and whether or not there should be metal detectors and security cameras at school.
  • The game now properly tracks Study Points (if you put Study Points into a school subject, then load an earlier save, your number of study points will revert back to whatever number they were when the game was saved.)
  • Characters who were “patrolling” at the time of a save will now resume their patrol accurately upon loading that save, instead of returning to their original patrol point whenever a save is loaded.
  • If the player spilled blood, saved the game, then cleaned up the blood and saved the game again, there was a bug that would re-spawn the blood pools that were cleaned up. This bug has been fixed.
  • Lockers that you can hide bodies inside of now have cyan outlines in Yandere Vision (like every other tool that facilitates getting away with murder).
  • There is now a “How to make money” tutorial pop-up when you try to purchase things at school without having enough money to buy anything.
  • From now on, if you crush a phone with your foot while carrying or dragging a corpse, you’ll drop the corpse before crushing the phone.
  • It is no longer possible to view Senpai’s student profile in Mission Mode, since he is canonically dead in the Mission Mode Timeline.
  • If the player drags a corpse nearby the mythical tree behind the school, that corpse will no longer spawn blood pools.
  • It is no longer possible to leave bloody footprints within the proximity of the mythical tree behind the school.
  • Certain items (clean school uniform, money) can now be ordered from Info-chan multiple times in a single day.
  • The player will now see a new texture on Yandere-chan’s phone when taking a picture with the phone’s camera.
  • Because Musume’s Task requires Horuda to be alive, Musume’s Task is no longer available if Horuda is dead.
  • From now on, the jingle at the Calendar screen will sound creepier as school atmosphere drops lower.
  • From now on, the game will continue loading if the player alt+tabs while at the loading screen.
  • Saving/Loading now accurately tracks which bodies are currently hidden in which lockers.
  • It is no longer possible to steal a student’s phone if that student is watching you.
  • A delinquent can no longer shove you while he is solving a puzzle cube.
  • Replaced placeholder “new smartphone” graphic with original artwork.
  • Saving the game will now track the current location of the radio.
  • The Electronics Store now has appropriate theme music.
  • Added one new hairstyle for Yandere-chan.
  • Added a bunch of minor miscellaneous aesthetic changes (reducing poly count of models with too many polygons, updating a few props in the Drama Club, changing the color of the glass on the trophy cases, adding a few more glass cases near the entrance, etc.)

Bug Fixes

  • Fixed bug that would cause a member of the science club to perpetually walk into the school fountain if the player loaded a save that was created while that science club member was walking towards a storage closet.
  • Fixed bug that would prevent the “Dispose of Weapon” checkmark from filling in on the “How to get away with murder before the Police arrive” checklist, if the victim was killed without use of a weapon.

  • Fixed bug that caused the mouse cursor to be visible when launching the game, even though the mouse cursor is not used to make selections anywhere in Yandere Simulator.
  • Fixed bug that would cause the mouse cursor to appear onscreen when the player started a new game, even though the mouse cursor isn’t used at all in Yandere Simulator.
  • Fixed bug that would cause the game to fail to acknowledge that a corpse was hidden in a locker, if the corpse was removed from the locker and placed back inside.
  • Fixed bug that would glitch out a mind-broken slave if the player visited the guidance counselor while a mind-broken slave was on her way to kill someone.
  • Fixed bug that would cause a Student Council girl to pepper-spray Yandere-chan after being kicked out of the Student Council, if she witnessed murder.

  • Fixed bug that would cause teachers in the Faculty Room to be completely unable to see Yandere-chan attacking a fellow teacher in the Faculty Room.
  • Fixed bug that would cause a corpse to permanently stop bleeding if it was put into a locker, taken out, put back inside, then taken out again.
  • Fixed bug that would cause the gym to stop rendering if the player aimed the camera downwards while walking around on the catwalks of the gym.
  • Fixed bug that would cause Taro Yamada’s name to be displayed as “Senpai” instead of “Taro Yamada” when first opening the Student Info menu.

  • Fixed bug that would cause male students’ bone structure and faces to change if they were placed into a locker and then removed from it.
  • Fixed bug that would cause “Disable Distant Animations” to snap to “25” if the player loaded into the school after setting it to “Off”.
  • Fixed bug that prevented some of the text in the Mission Mode menu from correctly updating when the player generated a random mission.
  • Fixed physics bug that would cause the “Where is my classroom” pink trail to collide with pickups and send them flying into the air.
  • Fixed bug that would cause Yandere-chan to permanently freeze in place if she used a stink bomb on a teacher while holding a weapon.
  • Fixed bug that would prevent the player from being able to adjust some of the game’s settings while inside of Yandere-chan’s home.
  • Fixed bug that caused cauterized corpses to produce blood pools if they were placed into a locker and then taken out of one.

Good News

Hey, guess what? I optimized a bunch of things in the school scene, and I don’t know which thing specifically made the biggest difference, but where I was previously getting an average framerate of 50~55, I am now getting an average framerate of 55~60. Woo hoo!

Return of the Pillowcases

After the Oka and Budo pillowcases were added to the Crowdmade store, I received inquiries about whether or not the previous pillowcases of Yandere-chan and Yandere-kun would ever return. I’m happy to announce that those pillowcases are now available in the Crowdmade store again! Go check ’em out!

  1. It would be a better idea if u change one girl of the club from first year classroom to Classroom 3-1.Eg Mina Rai from Classroom 1-2 to Classroom 3-1. And the boy of the clubs can be switched from Classroom 3-1 to Classroom 2-1.Eg Sho Kunin from Classroom 3-1 to Classroom 2-1.

  2. I thought it might be a good idea,just to balance the non concealable weapons more balanced.By making the police investigate them if they were out of place.Like, if you to the pipe wrench and killed someone you would have the option to place it back.If a weapon was out of place the police would take dna and if ayanos was found she would be arrested if no evidence was found to prove she didn’t do it.The perk would be that teachers dont call the police about these weapons, there only dangerous if you dont place them back and if police come to school

  3. Wait a minute, the build tha contains Osana is going to be the official demo ???? Are we actually this close ??!!!!

  4. imo the best way to balance the weapon is to add weapon cases that are in the killer alphabet challenge, which can be bought in info-chan or online store, then you can hide the weapon without suspicion but they will bleed

    • There is a way to get those cases though
      they belong to the delinquents, and you can steal pretty much anything a person has that isn’t nailed down
      So just steal their cases and badda bing badda boom

  5. Just stop it 🙄 yandere dev is still working on osana and he did metion in the last post that if there are bugs he would post a another build so just stop hating on him hes trying to get osana done and shouldn’t have to see people like you hiding behind a screen knowing fine well that you don’t have the audacity to say it to his face. Aka shut up 😁

  6. Glad to see some bugs have been fixed 😊 i can’t wait for osana to come out and there to be a official demo to the game 😁 keep working hard your doing a really good job on the game! Dont let anyone get you down ☺️

  7. Has anyone else been having issues trying to download the latest build? I’ve at least tried four times to download it directly from the launcher, but each time I try, my computer tells me that it won’t download it. I just want to know if anyone else is having this problem.

  8. I know is importante that every type of weapon have one beneficios and one defect, but technically when you hit someone with a baseball bat, that person bleeds. But anyway is my opinion, i still love the game.

  9. hi yandere dev, when i was installing yandere simulator on my computer on this website
    But, did I get a virus when installing yandere, is it the application or is it the website?

  10. This is random but I always thought that it would be a good idea for a way to befriend a rival is by watching them do something they enjoy. What I mean is that I always thought that it would be cool for Megami to be an ice skater and a way to befriend her is to got to a competition of hers to keep her company

  11. yanderedev is working very hard on this game and he does his best, and that makes me very happy, and I congratulate him for his great work

  12. i hope one day there will be bodypillows with each one of the rivals!
    can’t wait to hug my favourite honey bun amai💕

  13. I would’ve loved to buy a Yandere-kun pillow case but I’m from a very religious family so my parents would kill me😩😩😩

  14. I think when the player gets near a corpse, Ayano should lose a little bit of her sanity. I want it to be more challenging to get away with murder, because now I think it’s way too easy. Just a suggestion.

    • Wouldn’t it become too hard for beginners to play the game? Maybe if you play the game longer (in the time of gameplay) the harder it gets or something like that.

      • Maybe Yandere Dev could (once Osana’s released) implement a difficulty setting and the sanity around corpses thing could be something on a higher difficulty.

  15. So the SC member’s voiced lines are going to come in the next build hopefully, but will Megami’s ever change ? Or stay the same until she’s there ? Love the game 😉

  16. Hey Yanderedev
    Will you put props on the others floors like you did on the 1st floor or not,I’m just curious

  17. Hey yandere dev I believe I already asked this question have been busy so its hard to remember lol but anyways will you ever give the names of the rivals parents? Like Megamis mother for example or will we have to find out in game? Anyways great job on the game! And have a fantastic day!

  18. I love how much amazing progress you are making! keep it up! you have such wonderful skills and i cant wait to play. Just one thing, osana is supposed to be the easiest rival to kill, so don’t feel pressured to make it super hard to kill her, everyone will love the game no matter what and we understand that the other rivals will be harder to beat. The reason i say this is, if she is too hard to kill then the players may get frustrated knowing that it gets harder every time, they should only feel this way later in the game, not for the first rival. Have a wonderful day and keep up the amazing work.

  19. I have couple questions. I noticed you have a lot of empty spaces around the school. Are you going to eventually fill those in or leave them barren? Also if you decide to fill them in what will they look like and be filled with? If you decide to leave them barren is that for a purpose? If so what purpose would that be?

  20. de berian aser gue el juego se pudiera jugar sin tener gue escagar para cuaguier cuputadora yo tengo el guego descagado pero a y gente gue guiere juagar sin descagar

  21. Have you fixed the bug where there was no blood on the player but others still see it after showering?

  22. Wow and i want to ask is osana in the game or she is still not? Cause I heard someone said that she is in the game 😍

    • Some people have modded the game to make Osana spawn, but these mods do not give you the true “Osana Experience”. She’s not officially in the game yet.

  23. I know that there is a download for mac but it doesn’t work for me. Does anybody else know how to get it on mac? I’ve tried the download on this site, winebox, and a few others but none of them work.

  24. okay so i absolutely love how much work youve put into this game and im beyond grateful and i really hope you read this because i was wondering if after everything is perfect and youre happy with the way it is and youre looking for something new to add to the game maybe you could try a free mode ? where all the same mechanics are there and everything except you get to pick your suitor say if you want to fall in love with one of the delinquents or a random boy or girl or club leader, you could choose them before you start the game kind of like how you pick what senpai looks like before the game loads. like it could send completely random girls after him and you have to stop them passively or agressively like with senpai except maybe you could make it so that you can talk to the suitor and make him fall in love with you ? i dont expect you to do this but i just thought it would be really cool. thanks for your time !!!

    • I would like to put a “free mode” or “endless mode” in the final game, but it’s not a priority for the current debug sandbox or the Osana demo.

      Thanks for your kind words, though!

  25. Recently, I compared the latest build of YandereSimulator to the build of YandereSimulator from 2014 to 2019. It is so good to see YandereSimulator develop. 🙂

  26. Will there be a consequence if Yandere-Chan murders all of her classmates? Wouldn’t it be weird if it was just her and the teacher?

    • There is a secret ending, if you kill all the classmates and teachers and only senpai is left in school then an ending triggers, oh and if you kill up to 50 students then the next day the school is shut down

  27. Will it be possible for the player to view their reputation from their phone? Or like a tutorial window or something pops up every time the players reputation takes damage when they aren’t at school like after we kidnap a girl it’s say your reputation has taken 10 damage or something or like if on the weekends we do side stuff to gain or lose reputation outside of school

  28. Actually yes. Unless it’s been changed recently, if 50 students are killed the headmaster will shutdown the school and then Senpai is transferred to another school. Ayano will lose the ability to pursue Senpai, and it will result in game over.

  29. YandereDev will you put the rest of the basement tapes before or after demo release,I wanna discover more thing about Yansim’s history

    • He said that there’s no need to add the basement tapes right now because in order to unlock the basement tapes, you have to kidnap a girl each week. Ayano would have to make space in her basement for new kidnapped victims and would find the tapes underneath the boxes and stuff.
