October 9th Bug-Fixing Build

Oops! There were a lot of embarrassing bugs in the previous build of the game. A new build has been uploaded. You can grab it from the Downloads page.

Scroll down for a list of the bugs that I fixed in this build!

Bug Fixes

  • Fixed bug that would prevent the player from selecting a student to distract when attempting to tell a friend to go distract someone.
  • Fixed bug that would cause a student to enter the “Distracted” state permanently if the student who was distracting them was killed.
  • Fixed bug that would cause controller buttons to appear on the social media website when the player was using a keyboard.
  • Fixed bug that would allow the player to gossip to a student about themself, under specific circumstances.
  • Fixed bug that would cause the game to become unresponsive if the player attempted to apologize.
  • Fixed bug that would cause two text messages from Info-chan to overlay on top of each other.
  • Fixed bug that would prevent Kokona from discovering a letter left inside of her locker.
  • Fixed bug that would cause Kokona to walk in place during her Wednesday lunchtime event.
  • Fixed bug that would cause Senpai’s eyes to point in different directions…I think.
  • Fixed bug that would change the color of the letter left inside of Kokona’s locker.
  • Fixed bug that was causing the word “Sleep” above Yandere-chan’s bed to flicker.
  • Fixed bug that would allow the player to gossip about teachers.
  • Changed the cost of a girl’s dark secret from 10 panty shots to 8 panty shots.

Phew! Hopefully those were all of the major bugs. I hope that there aren’t any other game-breaking bugs left in the current build!

Also, I hate to be a Negative Nancy, but it’s about time for me to remind people to read this blog post.

Thank you for following Yandere Simulator’s development!

Friendship, Gossip, and Bullying

I’ve finally prepared a new build of the game! This build introduces the concepts of friendship, gossiping, and bullying to the game.

This video should explain everything:

In addition to those features, some other miscellaneous improvements were added to the game. Here’s a full list of everything that’s new in this build:


  • It is now possible to damage a student’s reputation by gossiping about them with other NPCs.
  • It is not possible to gossip if your reputation is “Bad”.
  • You cannot gossip with a student more than once per day.
  • Gossiping damages your own reputation.
  • Having a high reputation will enhance the effect of your gossip.
  • Wearing the right panties will enhance the effect of your gossip.
  • You can pay Info-chan for information that will enhance the effect of your gossip.
  • Being friends with a student will enhance the effect of your gossip with that student.
  • It is possible to damage a student’s reputation by badmouthing them on social media.
  • If you lie on the Internet, your reputation will drop.
  • If you expose your rival’s dirty secrets on the Internet, her reputation will drop.
  • You can check a student’s reputation on your smartphone’s “Student Info” screen.
  • If a student’s reputation drops low enough, they will no longer be welcome around other students, and will sit alone instead of socializing.
  • If a student’s reputation drops low enough, other students will begin to vandalize that student’s desk.
  • If a student’s reputation drops low enough, they will stop coming to school.

Yandere-chan’s Room

  • Added night and day to Yandere-chan’s room. Certain activities are only available during the day, others only available at night.
  • Added a bed for sleeping, a TV for gaming, a shelf for manga, and a computer for cyber-bullying.
  • Yandere-chan now gets her panties from a drawer instead of an armoire.
  • Replaced Yandere-chan’s room with a new environment model.
  • Added placeholder music tracks to Yandere-chan’s room.

Tasks and Friendship

  • It is now possible to use the “Task” option in the student interaction wheel to accept a task from a student. There is currently only one in the game.
  • If you complete a Task for a student, your reputation will improve, and that student will become your friend.
  • Being friends with a student enables you to access the Favors menu.
  • All of the options in the Favors menu are now operational. You can ask a friend to follow you, leave the area, or distract another NPC for you.
  • Being friends with a student also means that your compliments and gossip will have a stronger effect on that student.
  • You can check the status of all of your current Tasks on your smartphone’s “Task list” screen.

Other Improvements

  • Fixed a bug that would cause Senpai to have white hair and white eyes if the player made no selections whatsoever when customizing Senpai at the customization screen.
  • It is now possible to take photographs by aiming the camera and then pressing the CTRL button instead of the left mouse button. (“RB” for Xbox controller users.)
  • Attempted to fix the bug that would cause Yandere-chan and a student to freeze in place when Yandere-chan tried to interact with a student.
  • While speaking with an NPC, it is now possible to tap the “Confirm” button during a conversation to advance the text.
  • An audio clip now plays when trying to look up Info-chan’s information in the Student Info screen.
  • After you kidnap a girl, the girl who appears in your basement will have the correct hairstyle.
  • Fixed bug that would cause Osana Najimi to disappear under specific circumstances.
  • It is now possible to access the phone pause menu when in Yandere-chan’s room.
  • The “End-Of-Day Results” screen has been sped up to twice its previous speed.
  • There is now an operational vending machine on school grounds.
  • Added a new Easter egg.


  • Adjusted the contrast of the hair textures so that some hairstyles are not drastically darker than other hairstyles.
  • Fixed a problem that would cause Ryuto Ippongo’s bandana to appear black when viewed from a certain angle.
  • Gave the teachers unique hair and glasses so that they no longer look like clones of Yandere-chan.
  • Added three new hairstyles for Yandere-chan.
  • Gave Ryuto Ippongo some less-extreme hair.
  • Improved Pippi Osu’s hair.

If I’m still going by my “1st and 15th of every month” update schedule, then this update was 7 days late, and I only have 7 days to produce a new update. It would be impossible to implement something elaborate into the game in such a short span of time…but I can think of a few features that people have been begging for that wouldn’t take more than a few days to implement, so that might be the focus of the next build. However, I don’t want to make any promises just yet. We’ll just have to see how things turn out.

I Want My Senpai Back

All work and no play makes YandereDev morbidly depressed, so I decided to make something fun with the help of several very talented volunteers:

Check out the video description for a list of everyone involved in the production of the video!

Would you like to see more “just for fun” videos like this in the future, or do you think that I should never do anything like this ever again? Please let me know your thoughts in the comment section below.

October Update Preview

Heh heh heh…I know what I’ll do…instead of calling it a “delay apology”, I’ll call it an “update preview”…yeah…that’s a brilliant idea!


It is my honor and my privilege to present you with this thrilling Update Preview!

I plan to release another video within the next few days, and a new gameplay build shortly afterwards.

Sorry for the wait! I hope that this video gives you some things to speculate about and look forward to!
