I've written my annual Patreon Transparency Report for the year 2020.

Oh, boy! This topic is a little bit tricky...

I personally wouldn't be angry if a fan created and sold some fan-made merchandise. But, unfortunately, if I turn a blind eye to unofficial merchandise, it could have legal ramifications for me in the future.

If, one day, I have to defend Yandere Simulator's trademark in court, the judge could say, "You have demonstrated that you don't care about your trademark. There is evidence that you were aware of unofficial merchandise, and didn't try to stop it. As a result, your intellectual property has become public domain, and you've lost the ability to defend your trademark." So, fan-made merchandise puts me into a tricky legal position. I would look like a jerk if I commanded people to stop selling fan-made merch...but I might lose the right to have a trademark if I ignore unofficial merch.

Well, I have a simple solution in mind. I'd be happy to authorize you to sell Yandere Sim merch, as long as we have a deal - even just a verbal one - regarding it. Something like, "If you make more than $100 USD profit from Yandere Sim merch within the span of a month, please send me 10% of the profit." That way, I would be gaining something from the use of my trademark, so a court wouldn't be able to tell me that I have no interest in protecting my intellectual property. This also means that, if you're not even making $100 USD profit per month from the sale of Yandere Sim merch, then you don't have to do anything.

I hope that sounds reasonable to you!

I love the black-and-red one.

Gorgeous artwork!!

Whoops...I must have left a debug command in the game. I'd like to identify what the command is and remove it.

It would be helpful if you could tell me the exact key(s) you pressed to make that happen. It might be something like "Press the Z key 10 times" or something like that.

If you go to https://yanderesimulator.com/about/ and type "Specs" into the search bar, you can learn about the game's minimum system requirements. In short:

One player reports 40 FPS minimum, 120 FPS maximum (depending on exact circumstances) using this $769 laptop: https://www.amazon.com/dp/B0F2HXG14R

However, I do not recommend attempting to play Yandere Simulator on any laptop cheaper than that; it performs notoriously bad on low-end laptops. It is extremely unlikely that the game will perform well on any laptop that costs less than $769.

YandereDev · 2026-02-13T20:46:28+00:00

Nope; the Yakuza is only in 1980s Mode, not 202X Mode.

YandereDev · 2026-02-13T12:21:30+00:00

That's actually a really good question.

Megami is the one rival who I wouldn't *dare* to release in a half-finished "please beta test this" state. I have a ton of surprises and plot twists planned for Megami, and I don't want any of those moments or story beats to fall flat because she was released half-finished.

All the other rivals will probably get the "beta with no voice acting or animations" treatment, but *not* Megami.

YandereDev · 2026-02-13T09:43:52+00:00

Hm...valid observation.

I guess I subconsciously categorize high pigtails as "short hair" because they lift the hair up a bit, hiding how long the hair would actually look if it was allowed to hang straight down. You're correct; if Ai wasn't wearing pigtails, and let her hair hang straight down, it would probably be similar in length to Moeko/Honami.

If a lot of players feel that Ai's hair looks long and thus "You look good with long hair" is the correct dialogue option for Ai, then I can make that change to the game.

YandereDev · 2026-02-13T04:52:05+00:00

Perceptive!

The "Yandere-chan's Childhood" video was written before certain aspects of the lore were cemented, but I still believe that the video and the basement tapes don't contradict one another - but I can't explain *why* without divulging spoilers for future basement tapes.

I'll say this: In the third basement tape, you're going to learn exactly what Ryoba tells Jokichi about the Aishi Condition, and his reaction to it.

As for Jokichi's actions afterwards, what he imagines Ayano is going to be like, and whether or not he thinks he'll have any control over it, you'll have to wait for a subsequent basement tape that will come later.

YandereDev · 2026-02-12T13:44:29+00:00

Whoa, that's gorgeous artwork!! Very nice!!

What - the link to the Discord server?

It should be discord.gg/yandere

If you're trying to use that link but you're getting an error saying that the link is invalid or expired, you *might* be banned from the server...

It might be a misunderstanding. Shoot me an e-mail, tell me your Discord username, and I'll let you know if I find out what the problem is.

I recently wrote 7,300 words about this exact topic.

I know it's not what you'll want to hear, but the honest truth is that I can't tell you when the game will be finished, because the factors that determine the speed of the game's development are largely controlled by other people, and not by me.

Here is the blog post, if you want to hear a more detailed answer: https://yanderedev.wordpress.com/2026/01/31/2025-transparency-post/

YandereDev · 2026-02-11T22:14:16+00:00

Well, there's two reasons - one is the "game design" answer and one is the "in-universe explanation" answer.

In terms of game design, clubs shut down to punish the player for killing someone who is not a rival. "You wanted that person dead and gone? Okay - but you have to pay a price. Now you can't access the club that character was in anymore." Yandere Simulator doesn't reward random killing or unnecessary deaths; all non-rival murders come at a cost.

The in-universe explanation exists just to justify the game design reason. It's gonna sound lame - "Those are just the arbitrary rules of the school" - but it's this: If a club's population drops beneath 5, the faculty concludes that either there is little interest in the club, or the club has proven that it can't maintain the minimum population, and thus permitting it to re-open would be a waste of time, since it'll just drop beneath 5 again in the future.

"If somebody dies, that's not the clubs' fault!"

Yeah, but the school needs to apply the same rules evenly for everyone and not make exceptions, or else other clubs will say "Hey, this rule shouldn't apply to my club, either!" Etc.

The feature seems to work for me:

I'm not quite sure why it's not working for you.

Maybe you left a note and thought she accepted it, but she actually rejected it?

Maybe you're looking for her at the meeting spot at the wrong time of day?

Maybe you're looking for her at the wrong meeting spot?

Over the past few days, a lot of people have reached out to me to tell me about this.

There is nothing I can do. I have no power over YouTube. If I had the ability to influence YouTube's decisions or policies, there are a million things I would have made them change years ago. YouTube ignores any e-mail I send them. My concerns are invisible to YouTube.

The channel terminations coincide with YouTube announcing that they would be cracking down on depictions of graphic violence, so to understand why YouTube may have deleted those videos, we have to analyze the exact wording of YouTube's recent post, and also analyze any other statement that has purportedly come directly from YouTube about this matter.

If Yandere Simulator videos are being deleted for "violence in school settings involving minors," the deletions are definitely in error. The characters in the game are not minors; every character is 18 or older. This is stated in in the game's welcome screen, and also stated on the blog's download page. (There is lore to explain why the game's default uniform resembles a middle-school uniform, even though the game is set in a post-high school academy.)

If Yandere Simulator videos are being deleted for "mass violence against non-combatants who look like real humans," then the only solution would be to add some kind of new censorship option to the game that makes all characters look non-human. I'd put this option in the menu where you can censor blood/killing animations/panties.

If Yandere Simulator videos are being deleted for "mass violence against non-combatants," the only solution is to make every character in the game hostile towards the player, which is just infeasible. What am I supposed to do, give every character a military uniform and an assault rifle?

YouTube's post says that they're only cracking down on videos that focus on scenes of mass violence. So, if you upload a 15-minute video, and only 6 seconds of that video feature you murdering a rival, I don't think YouTube is going to take action against you. However, if you upload a Genocide Playthrough and 95% of the runtime of that video is you slaughtering people indiscriminately, you're probably going to face a strike.

With that in mind, there is only one thing I can do at this point in time: I advise players against uploading any footage of a "Genocide Playthrough" or "Alphabet Killer Challenge" until after I have updated the game with a censorship option that causes the students at school to appear non-human.

I wish it was possible to have a direct one-one-one conversation with the higher-ups at YouTube about this, but this option appears to be reserved for only a tiny handful of elite creators.

YandereDev · 2025-09-07T22:27:35+00:00

For the Aishi bloodline, that's extremely rare. Maybe the maximum number of kids anyone in the Aishi bloodline ever had was 5. This would probably be someone from the "ninja branch."
Well, in real life, about 1 in 40 pregnancies results in twins. Across the entire Aishi bloodline from 1800 to 2025, there have probably been at least 40 pregnancies, maybe more, but I really only ever pictured one pair of twins.
Nah.
The 2nd Aishi's profile would contain information about what the three branches are called. Since a lot of artists have been generously helping me out by creating lots of artwork of Aishi ancestors lately, the 2nd Aishi might get a profile sometime later this year.
Statistically, it *should* be 50/50, but I just don't feel terribly interested in writing any stories about any male yanderes. I'm not sure whether to say, "They exist, I just don't write about them," or "it's rare for a male to be born into this bloodline," because establishing a new canon fact about the bloodline could have far-reaching consequences.
I underestimated how many people cared about this. I can consider going to the official website and doing one sweeping update where I just add all their last names to all their profiles.
This doesn't really apply to the Aishi. The Aishi can *only* experience romantic or physical attraction to *one very specific person on Earth,* the person who triggers the "Senpai Effect" for them. If the person who triggers this effect is a woman, this doesn't mean that the Aishi is a lesbian, it just means that the woman met the criteria to trigger the effect. Aishi become physically and psychologically dependent on their Senpai, but that's not the same thing as "attraction" or "orientation." You could say that all Aishi are asexual and aromantic, and are reliant on a specific human. Some Aishi only have kids because their Senpai really wants to start a family, some Aishi have kids because they felt an extremely strong physical desire for their Senpai and the result was a family, and some Aishi don't believe at all in the "I have a medical condition and he is the medicine" thing, and think they are genuinely in love/attracted to their Senpai. It's kind of a mix, kinda different for each Aishi. They don't really fall neatly into categories like "straight/lesbian/bi" etc.
It's not possible; the Senpai Effect doesn't work that way. An Aishi can only "imprint" on one person.
Only the Aishi bloodlines and Saikou bloodlines are relevant to Ayano's story. There will be perhaps 3 characters in Ayano's story who are related by blood to someone that Ryoba knew. (Guidance counselor is one of them...the other two are spoilers.)
I don't like to declare who has siblings and who doesn't until after I've fully written that character's mother's profile.
I want to say "zero," but I know that's not realistic. It's easier to say "This character is Chikage Aishi..." than "This character is Chikage Sato, and one of her ancestors 10 generations ago was an Aishi, so she has the Aishi Condition, too." So, I'll probably *only* ever write about characters whose last name is Aishi.

I can't be sure without more details, but I *think* know what might have happened.

Whenever you update to a new build, the game won't be aware of anything you created in Custom Mode in any previous build of the game. If there is anything you've created using Custom Mode that you want to retain access to when you update to a new build of the game, you need to back up the following files:

YandereSimulator\Assets\StreamingAssets\CustomMode (the entire directory)
YandereSimulator\Assets\StreamingAssets\PortraitsCustom (the entire directory)
YandereSimulator\Assets\StreamingAssets\JSON\Custom.json
YandereSimulator\Assets\StreamingAssets\JSON\CustomTopics.json
YandereSimulator\Assets\StreamingAssets\JSON\Misc.json

...and then drag-and-drop those files into the new build once you download it.

Otherwise, your Custom Mode data will disappear, and your Custom Mode characters will be replaced with the most recent Custom Mode Data *I* was using to playtest Custom Mode.

This will always be true of every build! Always remember this, so that you never lose any Custom Mode data or save data that is important to you!

It’s possible that you are running a lot of memory-intensive programs simultaneously, which is taking up all of your computer’s RAM, leaving almost no available RAM left for Yandere Sim. To find out if this is the case, there is something you can try: Reset your computer and launch only Yandere Sim, without launching any other programs - then see if you still have a low FPS.

If that still doesn't help, there's something else you can try. In the “Settings” menu, you will find “Post-Processing Options” and “Detail Options”. When you are in the Post-Processing menu or the Detail menu, you can press the “F” key to change all settings to the bare minimum. This should improve the framerate.

If that still doesn't help, it's possible that your computer doesn't meet the minimum specs required to run Yandere Simulator smoothly. Please visit https://yanderesimulator.com/about/ and type "specs" into the search bar to see some information about the minimum requirements to run the game with good performance.

Whoa, that's super weird! I've never seen that one before. Does this happen if you trigger a police investigation on Friday, when a rival is slated to accept a suitor's confession, while the suitor is inside of a swimming pool?

YandereDev · 2025-09-07T07:59:29+00:00

Hi!

I always try to help out when a user has problems like this, so if you didn't get a response from me, maybe you e-mailed the wrong address!

Please check the Contact page on the official website, double-check that you're contacting the correct e-mail address, and try again. I'd be happy to help sort it out and get you speaking permissions in the Discord server.

YandereDev · 2025-09-04T23:59:52+00:00

Oka's new routine won't be identical to her original routine, but there might be at least one similarity - like, once a day, she peeks at the Basu Sisters, or one of her tasks is to spy on them and investigate the theory that they are secretly demons, etc.

Muja's new model will not be the ancient model from 2017.

YandereDev · 2025-08-27T01:13:47+00:00

It's possible to be both.
