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 Yandere-chan to permanently freeze in place if she used a stink bomb on a teacher while holding a weapon.

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. I’ve noticed saki’s breasts are not the same size when she was carrying the tray. before she was carrying a tray, her breasts were at the size that it’s supposed to be. while she’s carrying the tray I think the breast size resets to 1 instead of it staying at 1.8

  2. I’m so excited to see what awesome improvements you’ve made to the game when you implement Osana! 🙂

    I do have one question though, are you going to change their uniforms? The current uniforms they have are for middle school students, not high school students. (I’m not trying to sound like a picky person, I was just curious is all) 🙂

    • You can change the uniforms in the Senpai customization screen if you don’t like the middle school uniform

  3. Hello, I would like to ask you something, do you think that in the future it could be translated into Spanish? And I’m not talking about the voices, but only the texts of the actions, dialogues and that kind of thing, please, I love the game as well, but those of us who don’t speak very good English could use a translation and would enjoy it. much more the game

    • Yandere Dev said that since the script keeps changing, the translation would become outdated quickly, so he needs to wait for the script to stop changing. Maybe after the demo is released, there will be a first translation ?

  4. Something tells me the environment is going to change soon. I remember seeing one of the checklists being something about changing the games environment.

  5. Dear Yandere dev,
    I was wondering if it is possible to change the students walking ways so instead of walking behind eachother like a conga line they waled side by side or something similar. I personally have no problem with this but when I watch people playing yandere simulator for the first time all of them say things like “normal people dont walk like that” or something similar. I just want to know if it is even possible to do since there are lots of students??

  6. Wonder if he is actually fixing his code to improve the frame-rate. I wouldn’t even mind waiting another year for Osana if the game could function and update faster

  7. Yandere dev, PLEASE, fix the bug that won’t allow me to dip a mop in a bucket. It’s SOO annoying!!!!!!!!!!

  8. Hey Yandere Dev, I found a bug to do with the gaming club:

    If you join the gaming club, then play a game to boost your stats, then save/load, the stat you boosted will return to rank 0.

    Also question: will we be able to customise controls in the demo or final game?

    • “Added one new hairstyle for Yandere-chan.” FINALLY

      Seriously though, great work Yandere-dev! Bug can be so hard to find and so random at times. You just don’t expect to see a pink line being a physics launcher. I hope we’ll get to have a copule weeks after Osana is released, before you put it on kickstarter. Im sure three’ll be lots of bugs and glitches and the like that no one person could ever hope to find on their own.

  9. Hi, I love the game, but the save/loading bugs are driving me insane! For example, if I save at say 3:30pm then get caught sometime after that, then I reload, I am back at 7:30am but it says “Cleaning Time” and all the students go to class and are stuck there.

    • Huh, that’s interesting. Can you repeat this bug anytime you try to make it happen, or does it only happen under specific circumstances? (For example, only on days when a memorial for a dead student occurred?)

  10. Hey YanDev, This keeps happening, whenever i kill someone the time i killed someone (ex: i killed them in lunchtime) the time goes back to 7:30. its annoying me.

  11. Is it just me or does the drama club have curtains that expand to hide the whole back now? When I reloaded the game the curtains weren’t there anymore

  12. Osana finally I have just found out about this game 3 months ago by kubz scouts and Razzbowski keep doing what your doing you rock!
