May 15 update (archive)
I’ve got a new build for you today!

To read the list of everything that was added/changed/fixed/improved in the latest build, please scroll down past this artwork of a sadistic chainsaw-wielding Ayano, drawn by an artist using the pseudonym Ayano Aishi!



Improvements

  • The “Ayano discovers corpse and sword under cherry tree” cutscene now has voice-acting for Ayano! Well, I’m using the words “voice acting” loosely here, because it’s just gasps and “Hmm…” sounds – but, that’s still technically voice acting! This scene may be updated again in the future with a few more “Hm?”-type noises, and potentially might get updated with lip-sync, too.
  • One of the paintings hanging in the Aishi home was a painting of a panda. This was pretty random (and a lot of people accused the panda of being AI-generated) so it has been replaced with an original illustration depicting Jokichi and Ryoba on their wedding day. (This image may be updated in the future.)
  • If you have enough Info Points to unlock a student’s profile, you can now unlock it from the Student Info menu instead of going into Info Chan’s Services menu to unlock it.
  • The kitten near the incinerator area will now meow when you stand close to it. (There is a 1-in-100 chance that it will meow in an unusual way…)
  • Amai now eats lunch after her Monday lunchtime event with Senpai, which allows the player to kill her with poison as early as Monday afternoon.
  • There is now an 1980s Mode version of Schoolday 12, meaning that all 13 Schoolday tracks now have 80s equivalents in 1980s Mode!
  • Raibaru’s unique socks have been added to the list of socks you can choose when editing a character in Pose Mode or Custom Mode.
  • The cops during the end-of-day police investigation sequence now have unique faces, instead of all being clones of one another.
  • Updated the artwork for the Dark Delights advertisement that can be found in the street where you can buy things from shops.
  • There is now a “MISSING” poster for Sumire outside of Ryoba’s classroom in 1989.
  • The “hint silhouette” for Budo’s Task now reflects Raibaru’s new appearance.
  • Tsubaki (one of the gardening club girls) now has hair physics.
  • Updated Osana’s swimsuit texture.
  • Updated Iruka’s hair texture.
  • Updated Seiyo’s hair texture.
  • Updated Ajia’s hair texture.

Fixes

  • In Custom Mode, if the player went into town and stood in a specific location and angled their camera in a specific way, parts of their 3D model would be rendered in the corner of the screen by an invisible camera that is normally not meant to be active. This bug has been fixed.
  • If School Atmosphere was low in the 5th week of 1980s Mode, a “Sleuth” character who had sunbathing in their schedule would walk up to a student at school and then change into their swimsuit in front of that character. This bug has been fixed.
  • In Custom Mode, when the player tried to use the color picker to choose the protagonist’s eye color, her eyes would not update instantly as the color was being picked, and would only update after the window was closed. This bug has been fixed.
  • If the player used the “pass time book” in the school library to advance to the next phase of the day while a student was wet, that student would not perform the rest of their daily routine properly. This bug can no longer occur.
  • If the player attended Light Music Club club activities with the camera between the club leader and her microphone stand, then Ryoba would “orbit” around the club leader like the moon orbiting the earth. This bug has been fixed.
  • If a mind-broken slave began to commit a murder-suicide and the player opened their map at the very beginning of the animation, the victim would die immediately and the slave would commit suicide. This bug is no longer possible.
  • If the player saved their game while a student was sunbathing and then loaded the save, the sunbathing student would walk back to their locker in the shower building instead of resuming sunbathing. This bug is now fixed.
  • While fixing a bug that prevented students from noticing you taking panty shots, I accidentally made all students instantly notice you taking a panty shot from any distance. This bug has been fixed.
  • If the player killed Osana using the rooftop fan, cleaned up all the blood, and tried to go to class, the game would incorrectly believe that there was blood present at school. This bug has been fixed.
  • In Custom Mode, if the player designed a student who sleeps in the school infirmary, the “smother” option would not be available when that student was sleeping. This bug has been fixed.
  • It was possible for the player to activate the “cut rope and drop sandbag” button prompt while standing 8 meters below it, instead of directly next to it. This bug has been fixed.
  • If Senpai was not at school (stayed home to mourn the death of a rival), the “leave a gift on Senpai’s desk” button prompt would still appear at his desk. This bug has been fixed.
  • If the player framed a student for murder, in the “Cop analyzes DNA” scene, the cop’s hands would be empty, instead of holding the appropriate prop. This bug has been fixed.
  • If the player used the mirror in Ayano’s home to customize her hairstyle and then went to town, Ayano’s default hair would return. This bug has been fixed.
  • In 1980s Mode, if the player played the Light Music Club minigame, the 202X Mode laptops would appear in Classroom 2-2. This bug has been fixed.
  • The “kitten turns its head to look at you when you’re nearby” functionality broke at some point in time. It has been restored.
  • If a bottle of Bleach fell upside-down, the player would lose the ability to pick it up again. This bug has been fixed.
  • The Dark Delights advertisement was appearing in 1989, a time period when it shouldn’t exist. This bug has been fixed.
  • On some computers, the PPStarrs easter egg was rendered with the wrong face texture. This bug has been fixed.
  • Raibaru still wore her loose socks even after changing into her swimsuit. This was a bug; it has been fixed.
  • Due to a bug, Nemesis was always spawning wearing Raibaru’s new socks. This bug has been fixed.
  • Due to a bug, Senpai’s student portrait looked all weird and stupid. This bug has been fixed.
  • Some of the corpses in the intro cutscene were bald. Oops! This bug has been fixed.
  • Fixed 4 typos in Osana’s subtitles.

Authorized Fan Merch

I’ve authorized another Chinese fan of the game to manufacture and sell Yandere Simulator merchandise. If you’re curious, you can check them out here: https://ko-fi.com/hmkrl

That’s it?

I apologize if today’s build seems underwhelming. I was planning to include a lot more content, but a lot of things didn’t fall into place.

For example: Last week, I mentioned that I had new voice lines for Amai, and was going to add them to the game as soon as her “Amai Meets Senpai” animation had been updated so that her lip/mouth movements were synchronized to her new voice lines. However, the animator who was going to update the animation ran into a pretty serious problem; his computer died! So, that addition will have to wait until his computer gets fixed. No estimate on how long that’ll take.

I don’t want this blog post to look like a big list of sad whiny excuses, so I’m not going to bother listing out each reason why certain additions have been postponed. The only thing I’ll say is that I really hope the next 2 weeks go by a lot smoother than the previous 2 did.

Thank you for following the development of Yandere Simulator!
 
Oh boy, time to review the fix notes, I'm sure this won't cause any level of neurological trauma...

How in the actual fuck do you have a standalone render camera set up to trigger in specific orientation situations. This isn't merely "Quirky" this is actually retarded. I assume by the positioning and the "parts of their model" comment that this is the facecam that's sometimes used. So why would you ever have its trigger conditions matched up to angles and positions rather than a fucking boolean. Even an If/Else block is hard to make this retarded.

Paired animations strike again. What makes this one weirder than last is that the club leader absorbs the player into her hierarchy, rather than the prior one. Its doubly weird because you generally want any player initiated action to be player controlled, so if you're merging trees, the player should be the absorbing entity, not the other way around.
 
Ok It's like he's blatantly focusing on things that he could do after the games released. Oh wait he's been doing that for years.

Whoa, Cam, what is wrong? Why did you private this one? I thought "we've been lied to" and it all was just facts and logic! Can you private this one as well, please?

Also, why were you taking down so many of your videos, Cam? Are you afraid of something?

Also, funny detail. My video was ok for 1.5 years and then suddenly got removed. Can you guess who left the only fucking comment on the Rumble version after several days after this? You'll never guess!

Cam, if I ever find out that you had something to do with it, I will go medieval on your ass. You know I can do this, I am not your retarded ex-buttbuddy Diesel. And I have way more receipts than you do, believe me.
 
I am an informatics drop out with baseline understanding of how to run a development project and every time i drop into this thread i feel like i'm having a stroke. Typing Code and making things "work somehow" isn't what makes a programmer. This shit makes no sense.
 
I tried searching up Soul Calibur (and various spellings) in this thread to see if anyone clocked another example of Alex's sheer plagiarism. I found nothing except discussion about the rape fanfiction he wrote, so forgive me if somebody's already posted this. You guys probably already know about the Basu sister update with the mysterious cutscene under the sakura tree, right? But did anyone else notice that the weapon Ayano finds is a litte... familiar?

Screenshot 2025-05-20 145710.webp

Well it's basically Ivy's whip from Soul Calibur. Ivy isn't the only character to wield a sword whip in gaming but based on Alex's history, it's most likely he copied the idea from there.

On May 16 Alex posted about trying to fix the framerate with a new build. https://yanderedev.wordpress.com/2025/05/16/low-fps-try-this/ Archive: https://archive.ph/pmV6c

It ties in with the new bug fixing build post.
May 18 bug fixing build (archive)
In the previous build, the game was configured to use “Direct3D 12” instead of “Direct3D 11.” Apparently, this caused a huge number of problems for many players, ranging from the game crashing at launch, to crashing when loading into the school, to crashing when opening the Student Info menu. Wow! What a mess! I had no idea that upgrading to Direct3D 12 could have those side-effects. I’ve decided to revert back to Direct3D 11 and release a new build.

To read about everything else that was added/changed/fixed/improved in the latest build, scroll down past this adorable illustration of Raibaru by Bynnyart!



Improvements

  • Cooking Club members will no longer drop their plates upon seeing the player in a suspicious state. They will only drop their plates if they see something on the ground that they know they have to report to a teacher (such as a pool of blood).
  • The wedding photo of Jokichi and Ryoba hanging in Ayano’s home has been replaced with new artwork. Jokichi and Ryoba are now in traditional Japanese wedding attire.
  • In a video that I uploaded in 2018, I said that any student with the “Spiteful” Persona would be immune to intimidation. This is now an aspect of the game.
  • I felt that the pose Sumire was doing in her “Missing” poster was not appropriate for her, so I’ve replaced it with a new pose.

Fixes

  • The confession cutscene at the end of Custom Mode was broken and not portraying the protagonist correctly or displaying text properly. The underlying issue that caused these problems has been resolved.
  • If the player was walking while accessing the “feed list,” the player would retain the ability to make the protagonist move around while making selections in the feed list. This bug has been fixed.
  • If the player used the “Unlock for 1 Info Point” feature to unlock a student’s profile on the Student Info screen, that student would not be outlined in Yandere Vision. This bug has been fixed.
  • In the last build, the game lost the ability to recognize that the player was taking a photograph of a kitten, which was essential for completing Riku’s Task. This bug has been fixed.
  • If the player tried to access the Student Info screen while at home, the game wouldn’t be able to properly populate the text at the bottom of the screen. This bug has been fixed.
  • Fixed typos and font inconsistencies on the Dark Delights poster in the town.
 
I'm probably derailig the thread but have you guys seen the utter insanity in the 'characters' section on the YS website?

There were a lot of characters added since I last visited and they have essay-long descriptions (which yet again proves Alex would be better off just writing a fanfiction rather than making a game), and most of them are crazy. Look at this shit.

Ayano's great grandma was apparently a fucking CIA asset.

I have never seen the phrase "mind-broken" used anywhere else than porn.

The preference for women being younger than men in relationships is a common creep thing I feel like. Not surprised it's included in the Aishi commandments.

Alex again attempting to explain dumb shit. The real reason why the succubus sisters have slanted pupils is because that were the textures provided in the unity model pack. This man is building his universe's lore on fucking bought assets lol

No, I am pretty sure Chris fucked his demented elderly mother. But yeah, that sounds somewhat like Alex.

Why would she care if that's not a real school anyway? Also, 'hey, Placeholder, what'cha doing, holding place for someone?" is like something straight out of Naked Gun movies. Only Alex takes it seriously.

"And the framerate drops because Aishi's curse causes time to bend around Ayano"

That sounds ominous.

His fanfiction would suck just as much ass, it's all just a gigantic wikifag dump of ~deep lore~ so he can jack off at the idea of engaging with discussions about pointless lore trivia and adding them to his wiki.

I'm pretty sure Chris at one point drew his trolls as characters in Sonichu and had them tortured, crucified and sent to hell. Great minds think alike.
Why would she care if that's not a real school anyway?
Jesus, I forgot that Academi isn't supposed to be a real highschool again. Every time I'm reminded of that I literally cannot believe how stupid this is.

Yeah, going by his earlier literary works, a fanfic would have been just as bad. Just saying that he is trying to cram all this storytelling and worldbuilding into a place where it doesn't belong. Funny to think at some point there was zero lore attached to this game - stabbing vocaloid highschoolers with no contex was a much better time to be had.

He's just too fucking stupid to even understand anime despite spending nearly two decades worth of time and autism with it. It's like pouring anime scripts into one of those really early language model AIs and telling it to write a story, it's just random shit he vaguely managed to grok as "cool" with zero understanding on what makes those tropes tick and how you can weave them together into a usable narrative.
 
@Gargoyle you missed this one. In fairness, I got this from r/Osana.

Goddamn, after all these years he's still sticking with those ridiculous fucking names. It's like that clip from Scary Movie 4 where they're speaking in mashed up Japanese words.
