Sharing a cute fan-made animation

A Japanese fan of Yandere Simulator has produced a video that is so cute, I just had to share it on my blog immediately:

It’s a parody of a video named “Kero” from 11 years ago. Want to hear an interesting coincidence? Earlier this month, I had this song stuck in my head, but couldn’t remember the name. At the exact moment that I was trying to remember the name of this song, somewhere out there in the world was working on a Yandere Sim fan video incorporating that exact song. The universe is funny sometimes!

Watching this video, I think it actually features every single student of 202X Mode. If the video’s creator actually managed to incorporate all 90 of 202X’s students into the video, that’s incredibly impressive!

Oh, you want a development update? I’ll say this: I’ve been getting very few bug reports recently, which means that I’ve been able to focus more time on my checklist items and less time fixing bugs. What a relief! (This also tells me that the game has finally become extremely stable and bug-free. That year of bug fixes really paid off!) Unless something important happens over the next 2 weeks, the next time you’ll hear from me will probably be March 31st for a blog post – and possibly a video – to discuss Yandere Simulator’s 9th anniversary of development.

March 15th Update

Hello! The past 2 weeks have been very productive. I knocked a lot of items off of my pre-crowdfunding checklist. Some are only half complete, since they are reliant on some other checklist item in order to be 100% complete, but I’m really happy with the process I made.

I’ve prepared a list of everything that was changed or fixed over the past two weeks – but first, I want to share something with you! An artist named Momo_Fujimi created a 24-page manga about Himari from the Gardening Club giving chocolate to all of the other students in class 3-1:

It’s a super cute and sweet manga, and it makes a lot of use of trivia that I have shared about the students over the years, such as the fact that Borupen’s favorite flavor is grape.

Please read the whole thing, because it’s absolutely adorable!

With that said, please click Continue Reading to read the rest of the blog post.

Nemesis Manga Update! Chapter 3 released!

On August 1, 2019, I released “Retribution”, a short manga that revealed the origins and motivations of “Nemesis”, the mysterious girl who hunts and kills Ayano in Mission Mode. Three years later, on March 19th, 2022, I released a sequel to that manga – a continuation of the story. It ended on a cliffhanger, with Ayano and Nemesis about to battle. I’m proud to announce that, after one year, Chapter 3 is ready!

Chapter 1 was 7 pages long, and Chapter 2 was 24 pages long. Chapter 3 is just a tiny bit shorter at 21 pages, but every one is packed with action! I really hope that you’re going to enjoy reading it!

(It’s formatted in the style of a traditional Japanese manga, so remember to read the panels from right to left!)

As you can see in the blog posts where each chapter of the manga was announced, the first two chapters of Retribution were translated into TWENTY different languages! A testament to the fact that no matter how many years pass, Yandere Simulator retains passionate fans all over the world! Just like before, foreign fans of the game are welcome to translate chapter 3 and e-mail me a link to a zip file containing all of the translated pages.

And, to make it easier for you, here’s a link to Chapter 3 without any words in the speech bubbles:

March 2nd Bug-Fixing build


Some users reported a bug that was making the corkboard sequence play in the daytime or play in 1980s Mode, which wasn’t intentional. I couldn’t actually replicate those bugs! However, I put in some code to manually force the game out of that situation if it ever somehow happens. I feel that it was important to release a new build with that adjustment as quickly as possible, so here’s a new build.

If Yandere Simulator had a small town, part of it might look like this…

Sometimes, I get a little curious. I think, “What if?” and I just want to set aside an hour or two to experiment a little bit.

You can download it here:

By the way, the music in this prototype was provided by DJ Volly! Check out his other work, too, it’s quite good.

February 21st Bug-Fixing Build

There was a bug preventing one of the tutorials from being completed, so I wanted to release a bug-fixing build.

The changelog for this build might look small, but that’s because I’ve been spending less of my time working on bug fixes and more of my time making progress on one of my checklist features. It’s almost complete, but I don’t plan to include it in the next build. Why? I’ll explain.

I’d like to collect information on how players complete their objectives when certain game mechanics are unavailable. What alternate strategies do players use when their default strategies are disallowed? Would players become frustrated with the game if they were no longer allowed to use certain features that they’ve become over-reliant on? Does the game actually become more fun and interesting when the player isn’t allowed to use certain shortcuts? What exploits are currently available that need to be fixed and removed?

To truly draw meaningful conclusions about these subjects, I would need to present players with a build of the game that is intended to be as balanced and exploit-free as possible, and then publicly challenge the playerbase to look for exploits and game-breaking flaws. The first step is patching up certain exploits that I’m already aware of, and making various changes to student and rival routines so that it’s never insanely easy to kill rivals with zero effort.

So, before I say, “Hey guys, play this build of the game and try to break it, I bet you can’t!” I first want to…

  1. Balance some mechanics that I know are already busted.
  2. Redesign some rival routines that I know are already full of exploits.
  3. Create an interface for enabling/disabling certain features, to challenge players to play the game with/without mechanics features being available.

One of those mechanics-that-needs-to-be-rebalanced is an aspect of the 1980s Mode tutorial, so we can add another item to the list:

4. Update the 1980s Mode tutorial to walk the player through the new version of an important rebalanced game mechanic.

In short, there is a long list of things I have to do before I can release the upcoming “Try and break the game, I dare you!” build. The point is to openly challenge players (and YouTubers) to try and expose exploits, and I want the game to be airtight before I do that. I’ll have to knock multiple things off of my checklist before I’ll be able to release a build that seems to contain a big exciting new feature, but when I do, I think you’re going to have fun playing the “I dare you to break it” update.

Okay! With that explanation out of the way, let’s move on. To see a list of the improvements and changes in the latest build, scroll down past this haunting artwork by haihondaitao!

February 16th Bug-Fixing Build

Hello! There was a bug in the previous build that was preventing two of the tutorials from being completed, and the tutorial is something that absolutely needs to work flawlessly so that new players don’t get confused, so I wanted to release a new build right away.

February 15th Bug-Fixing Build

Hey, remember when I said there wouldn’t be a build on the 15th? Haha, well…

Some annoying bugs were reported, so I decided to fix them all and upload a new build. To read a list of everything that was changed or fixed in the latest build, scroll down past this gorgeous artwork by AlaKZM4, depicting Ayano in the art style of Persona 5!

Happy Valentine’s Day!

Happy Valentine’s Day!

Valentine’s Day is a love-themed holiday, and Yandere Sim is a game about love (depending on how broadly you define the word “love”), so it feels wrong to let a Valentine’s Day pass by without making some kind of special post. I’ll be releasing a new build on the 15th, but for today, I’d like to share some of the coolest fan creations I’ve seen recently.

This video was created 6 months ago, but I didn’t actually discover it until recently! It’s absolutely amazing, please watch it!

And this cute little animation was made 3 whole years ago, but I didn’t even know it existed until yesterday! (Those teeth remind me of someone…)

I’m not even sure how creamstew_ekoda managed to make this video, but it’s hilarious to me:

In addition to those three videos, there are also dozens of fan-made illustrations I’d like to share. Please click Continue Reading to see what I’d like to show the community!
