  • The player can no longer change into a club uniform while they're covered in blood.
  • Adjusted the text that appears if a teacher discovers the corpse of a girl who seems to have committed suicide (but was actually pushed off the roof by Yandere-chan) so that the text is accurate no matter what time of day it appears.
  • Added Bad Time Mode.
  • There are now 7 Personality types, or “Personas” in total.
  • The 3 new ones are Coward, Evil, and Social Butterfly.
  • (Female) Students will now react when the player aims a camera at them. Their reaction depends on their personality.
  • For now, all male students will have the Loner personality or Teacher’s Pet personality, and will not react to the camera. I can’t give them other personalities or reactions because, at this point in time, I don’t have an animation rig for male characters, and I can’t transfer female animations to male skeletons.
  • If the player joins the Photography Club, students will not react to the camera, and will allow the player to Photograph them without any problems.
  • Added a humorous “WARNING” message to the beginning of the game. I might remove it, if people complain that it gives the game the wrong vibe.
  • Added a bunch of “Fake” students who exist so that the player can join clubs that don’t have official club leaders yet.
  • An accessory will now appear on Yandere-chan’s body when she joins certain clubs (Cooking, Occult, Martial Arts, Photography).

  • Added 6 new hairstyles for Yandere-chan.
  • Added 1 new hairstyle for Senpai-kun.
  • Ever since the first week of the game’s development, Yandere-chan’s eyes would shrink when she lost her sanity. Previously, her eyes would shrink into very small dots. This reflects an “angry” character, not a “hollow” character, so I have changed the minimum size of her eyes. Her eyes can still shrink, but not as much as before. Her eyes are meant to say “I am empty and dead inside”, and not “I am violent and crazy.”
  • Previously, Yandere-chan’s eyes would become blank and lifeless when “Yandere Vision” was activated. Now, they become blank when she loses sanity.
  • Now, when Yandere Vision is activated, Yandere-chan’s eyes become red.
  • A shadow now gradually falls over Yandere-chan’s face as she loses sanity.
  • It is no longer possible to tell a student to "Go Away" if they are currently walking from one place to another. It is now only possible to tell a student to "Go Away" if they have actually reached some destination that they intend to occupy for some time.
  • Previously, telling multiple students to "Go Away" would cause them to all travel to the exact same spot and attempt to occupy one position in space. Now, telling multiple students to "Go Away" causes them all to go to different spots.
  • Telling a student to "Go Away" will no longer make them spend hours standing alone somewhere. They will now only “Go Away” for a maximum of 60 seconds.
  • Students are no longer willing to perform favors for Yandere-chan if their next class begins in less than 30 minutes.
  • Gave original hair models to the first 6 female characters so that they don’t have to walk around wearing modified versions of Yandere-chan's hair.

  • Enabled more hairstyles for Senpai during Senpai customization.
  • Implemented a new hairstyle for Midori.

  • All body parts (head, torso, arms, legs) can be picked up, carried, dropped, and incinerated.
  • NPCs and police do not react to body parts yet.
  • As of now, dismemberment only works on females.
  • As of now, the body parts that appear after dismembering an NPC will always be clad in the default uniform.
  • It is now impossible to struggle against an NPC if the protagonist is holding a weapon that is too large to conceal, such as the katana or the circular saw. If a weapon is too large to conceal, then it's too unwieldy to use in close quarters and would only make Yandere-chan more vulnerable during a struggle.
  • At the request of an important person, all Undertale audio assets are now removed from the game, and the appearance of the "Gaster Blasters" has now been altered so that they are completely unique.
  • It is now possible to pick up a corpse and carry it while walking or running, if the player has leveled up their Physical Education stat at least one time.
  • Implemented a real "dump corpse into incinerator" animation, rather than re-purposing a "throw" animation in order to place a corpse into the incinerator.

  • It is now possible to dump corpses off the rooftop at locations where the railing is low enough.

  • Added a work-in-progress exterior to the school gymnasium.
  • Renamed Shi Ta to Shima Shita.
  • Added two new hairstyles for Senpai.
  • Mai Waifu now has rainbow-colored eyes. In other words, her eyes now gradually change their color, cycling through every color of the rainbow, every moment of the day.
  • Students now have a spoken reaction to witnessing the player carrying around a circular saw.
  • Attempted to implement support for all aspect ratios, not just the 16:9 aspect ratio that I've been using up until now. Warning: Any aspect ratio other than 16:9 will be buggy during Yandere Vision.
  • Yandere-chan now wears thigh-high stockings instead of leggings in all of her outfits.
  • Gave the titans in Titan Mode a new texture.
  • Removed several copyrighted tracks and replaced them with original tracks.
  • It is now possible to dismember male corpses.
  • Added the Ritual Knife and the Demonic Ritual.
  • Stabbing someone with the ritual knife brings Yandere-chan into a void with the Pain Demon, the Flame Demon, and the Lust Demon.
  • Pressing D twice will summon white hands to circle around Yandere-chan.

  • Removed the D debug command.
  • Replaced the sound effect when the player travels to the void.
  • Added new voiced lines for Flame Demon.
  • Added a new debug command to the debug menu; pressing the T key will cause the camera to switch to an "over-the-shoulder" viewpoint when fully zoomed in. Players who play with the camera zoomed in will actually be able to see what's around them.
  • Added a new background track to the game (that means adding 9 versions, one for each combination of atmosphere and sanity). When the school day begins, the player has a random chance of hearing the old track or the new track.

  • Placed delinquents outside of the garbage disposal zone.

  • Seven new hairstyles for Yandere-chan were implemented.
  • Changed the hair color of the corpses at the title screen.
  • Added fire extinguishers to the school.
  • Removed the "Warning" scene.
  • As of now, when multiple button prompts are visible onscreen, the game will highlight the one that is closest to the center of the screen, rather than the one that Yandere-chan is standing closest to. (This fixes the “Can’t pick up objects dropped near incinerator” bug.)
  • From now on, if a student witnesses a corpse while they are running to the locker room to change their clothing, they will switch their personality to “Loner” and run out of the school, instead of following their normal corpse-reaction routine.
  • Previously, when a student was following you, they would run when they were more than 5 meters away from you, and walk if they were less than 5 meters away from you. Now, students will run until they are 2 meters away from you.
  • Nearby pickups now have a little icon floating above them, instead of having a button prompt and name above them. The button prompt and the name of the object won’t actually appear until the player gets close enough.
  • Added textures to the castle area in Yanvania. Yes, that’s right, textures! Previously, the whole thing had no textures whatsoever! Everything was using solid colors until today! Check out Yanvania again!
  • When the player looks up a character’s information in the Student Info menu, “Club” will now change to “Occupation” when displaying the information of an adult.
  • Now, if the player kidnaps the week’s current rival, reduces her sanity to 0%, brings her to school, and hands her a weapon, she will commit suicide.
  • Updated Yandere-chan’s character model to use her trademark black stockings at the character customization screen.
  • Removed the ability to enter a changing booth while naked (it was causing bugs).
  • Senpai’s reaction to witnessing Yandere-chan taking panty shots is now voiced.

  • Added a hiding spot on the third floor outside of the computer room.

  • Added three new hairstyles for Yandere-chan.
  • Added a new hairstyle for Senpai.
  • Updated Mei Mio's hairstyle.
  • If the player puts Sakyu’s ring inside of Kokona’s book bag but does not report Kokona for theft, then Kokona will simply find Sakyu’s ring inside of her book bag and then return it to her after school, making it impossible to frame her for theft in the future.
  • Replaced the copyrighted music from the Cyborg Ninja easter egg with an original track by Damprog Music.
  • It is now possible to customize Senpai with facial hair.
  • Changed “Report Panties” to “Report Panty Shots”.

  • The answer sheet in the faculty room is now much more difficult to steal because teachers will react if they see Yandere-chan stealing the answer sheet, and the faculty room will always have at least one teacher inside of it.

  • Mind-broken slaves will now spawn to the right of the school gate, behind some bushes, to provide an explanation as to why the gym teacher and other students don’t notice them.

  • A character who has changed out of her school uniform will now no longer try to change shoes at their locker.
  • Implemented better “check locker for note” animations.
  • Improved the mind-broken slave’s suicide animation.
  • The idea with Social Butterflies is that they would run and hide in heavily-populated areas. However, if a murder occurs IN a heavily-populated area, then Social Butterflies “hide” right where they are standing. To combat this problem, Social Butterflies now run to a collective hiding spot and huddle together, rather than “hide” in plain view of the killer.
  • Researched and successfully implemented a method for modifying textures while the game is running. (You can currently only see one example of this in the game right now: Midori’s stockings and panties are now green.) This opens up tons of customization potential in the future!
  • Students who have witnessed Yandere-chan commit murder will now always perform a face-hiding animation if she aims her camera at them.

  • Added an easter egg connected to the turtle in the Light Music clubroom.
  • Added a kitten. (No functionality yet. Appearance not yet final.)

  • The “Press Q to censor panties” debug command now affects all of Yandere-chan’s school uniforms, and all female students.
  • Added a static effect to the screen when the player attempts to run out of the school grounds.

  • The player can use the Love menu to instruct a suitor to go talk to the current rival.
  • Once the rival and the suitor are alone together, the player can use the wireless headset to give instructions to the suitor as he speaks to the rival. This opens up a dating minigame.
  • If the player is able to raise the rival’s Affection Meter to 100% before 5:00 PM on Friday, the rival will put a love letter into her suitor’s locker that will cause them to go to the cherry tree outside of school.

  • Time will now pass at 50% normal speed during Lunchtime. This is because a lot of story events will occur at Lunchtime, and the game’s clock was ticking by way too fast for all of those events to occur within that phase of the day.
  • Improved the animations that Yandere-chan and students use when students are gathering around Yandere-chan and preparing to perform a group takedown on her.

  • Adjusted the settings for the “Rim Light Test” that is accessed by pressing the “R” key at the Settings menu. If you weren’t satisfied with how it looked before, try it again!
  • From now on, if the game is desaturated (because of low school atmosphere or LoveSick mode) the colors will temporarily return when Yandere-chan walks near Senpai.
  • There is no more “Yandere Simulator or LoveSick?” screen. Now, the only way to activate LoveSick Mode is to press “L” at the title screen.

  • The player will now hear a voice clip from Info-chan when setting a bug.
  • Previously, the player had to set a bucket of water above a doorway using the same button that opened and closed the doors, leading many players to accidentally set a bucket of water above a doorway when trying to open the door. In the latest build, the player will now use a different button to set a bucket of water above a doorway.
  • The “Gentle Eyes for Mai Waifu” feature it’s now properly disabled in this new build.
  • Senpai will now consider it to be suspicious when Yandere-chan is aiming a camera at his face, and will react the same way he does when Yandere-chan is acting weird in his general vicinity.
