Yandere Simulator



""After all, at its core, Yandere Simulator is a horror game. Where you are the monster...""

- YandereDev

A game in which you are a Yandere and must eliminate rivals for senpai's affection. Created by YandereDev as a Stealth Based Game, the goal is to eliminate all rivals for the affection of a boy your character likes while keeping everyone ignorant of it.

It is still in development, with a planned crowd-funding effort in the making. Old builds, which are not representative of the final game, can be downloaded on this fan site.

The game is currently PC only, though Mac and Linux builds are possibilities for the future.

Final Game
"...if you love someone, you shouldn't kidnap them and tie them to a chair!"
 * A Date with Rosie Palms: One of the ways to regain sanity is to personally use a picture of Senpai. I wonder what she's doing with that picture...
 * Adults Are Useless: Averted. Teachers and the police are remarkably competent. In the case of teachers, they can easily overpower Yandere-chan should she try to kill them. Unless of course, you gain the right skills or take them out less conspicuously.
 * Aluminum Christmas Trees: As peculiar as it might be for a school to have a convenient incinerator for Yandere-chan to use, it's Truth in Television. As some Japanese high schools have the students take charge of clean-up duty and waste disposal rather than relying on janitors, making the presence of an incinerator a necessity.
 * And That's Terrible:

""Yandere-chan will confess her love to Senpai when the time is right, once all of her rivals are eliminated. Until then... Don't. Let Senpai. Notice you.""
 * The Bad Guy Wins: If you win. Also in the lore.
 * Badass Bystander: In addition to the teachers, certain students with the "Heroic" personality can be this. As they'll not only try to stop Yandere-chan or fight back if she attacks them, but can also defeat her if she's not careful or prepared.
 * Bitch in Sheep's Clothing: It's possible for Yandere-chan to mercilessly wipe out her targets without anyone suspecting that someone as innocent or normal as her could have done it.
 * Bloodless Carnage: Averted. Killing people will likely result in a good deal of blood splatter, even on Yandere-chan. Which makes it all the more necessary to not only clean up the bloody mess, but also change clothes if need be before anyone notices.
 * Boss in Mook Clothing:
 * Teachers can easily overpower Yandere-chan unless she has the right skills or stats. Even then, it's not necessarily guaranteed that she'd succeed as there's still a struggle.
 * Japanese Delinquents are decidedly harder to kill than most students and can also overpower Yandere-chan if she's not careful.
 * Break the Badass/Break The Cutie/Break The Haughty: You can torture and mentally break captives until they're reduced to a hollow, barely-functioning shell.
 * Bullying a Dragon:
 * Gossiping about Yandere-chan is a very bad idea.
 * The game won't let you gossip about Info-chan.
 * Bi the Way: Senpai can be a female.
 * Cassandra Truth: Actually somewhat averted, at first, with However it doesn't last. Also if you move a body the teacher won't believe the student about a murder and rebukes them for 'playing a prank'. In the final version the teacher might not even believe a student saying that the student found a body or saw a murder if you moved the body the last time with this student too.
 * Censor Steam: When someone is naked, the stream covers only their private parts.
 * Compensated Dating: Some of the girls are involved in this activity. Yandere-chan can use the info to ruin their reputation.
 * Covert Pervert: Implied for some of the guys (and girls) in the school. Info-chan's Panty Shot photos are popular for a reason.
 * Creepy Monotone: Yandere-chan's completely tortured victims will speak in this manner.
 * Dark Reprise: The lower the overall atmosphere, the grimmer and more distorted the soundtrack becomes.
 * Daylight Horror: Yandere-chan can do all sorts of horrible crimes on a normal school day.
 * Decapitation Presentation: Yandere-chan can kill and dismember a student with a circular saw, then pick up the head, as showcased in the February (2016) Progress Update.
 * Dirty Business: A Hero Antagonist of the lore does this.
 * Dies Wide Open: Students who are poisoned, electrocuted or killed in a struggle.
 * Deconstructive Parody: The game is this to the classic High School Dating Sim set-up in addition to being an affectionate homage to Yanderes.
 * Driven to Suicide: You can bully a student so hard that he or she kills him- or herself.
 * The Eighties: The school's faculty are particularly concerned with making sure that a horrid series of murders that happened back in the 1980s doesn't happen again.
 * Emotionless Girl: Yandere-chan's backstory implies that she was this, until she saw Senpai.
 * Evil Laugh: If you commit a murder you lose sanity. Giving a evil laugh calms you down.
 * Fantastic Arousal: The more sanity Yandere-chan loses, the more perverse pleasure she seems to take with each kill, even if this makes her slower and more sloppy.
 * First-Name Basis: Ryoba's darling starts calling her by her first name shortly after they start talking for the first time. Isn't that romantic?
 * Fantasy Gun Control: Truth in Television given how Japanese gun laws and a general lack of firearms out in the open would make it highly unlikely for Yandere-chan to grab hold of one.
 * Gamer Girl: Yandere-chan can be made into one, especially with various games in the Computer Club that can give her temporary boosts to her skills for the day.
 * Generation Xerox: Ryoba Aishi, Yandere-chan's mother, is not only stated to look like an adult Yandere-chan, according to Word of God.
 * Genre Shift: The game's overall tone and even the atmosphere surrounding the school can change considerably depending on your actions. Playing as a particularly violent Yandere-chan is an easy way to turn said atmosphere from "classic High School drama" to "suspense thriller" very quickly.
 * Henpecked Husband: Yandere-chan's father is this. Given that his spouse is Ryoba Aishi, there's a very good reason for that.
 * Hidden in Plain Sight: You, generally.
 * Hope Spot: It's revealed in Yandere-chan's Origin Story that her father's efforts to help her be normal are this. And it's strongly implied that on the inside, he seems to have given up in changing her for the "better."
 * Immodest Orgasm: Ryoba sounds like she orgasms from darling using her first name.
 * Improbable Weapon User: Yandere-chan generally has to make do with whatever's on-hand, from knives and syringes to circular saws.
 * It Was Here, I Swear: You can move the body between when it is spotted and when a teacher shows up. The teacher scolds the student for "playing a prank", even if the you didn't mop up the blood. In the future a student who's been accused of "playing a prank" the first time around might not even be given another chance to convince the teacher.
 * It's a Wonderful Failure: Just as there are several ways for Yandere-chan to deal with her prey, there are also several ways for her to lose. Whether it's being caught by police or losing the affection of Senpai.
 * Japanese Delinquents: A rival, one of the strongest in the game, will display this type of behaviour and appearance.
 * Armed delinquents will be present near the incinerator, acting as obstacles to Yandere-chan. Getting hit in the head by one of them will get you a Game Over. They can be fooled by transporting a dismembered corpse inside a cello case or a garbage container (one body part at a time).
 * Karma Houdini: You, if you win. Also in the lore.
 * Kill It with Fire: Yandere-chan can burn her murdered victims as well as her blood-stained clothes with an incinerator. You can also put tranquilized, unconscious girls into the incinerator and burn them.
 * Leave No Witnesses: If people, cowards and evil students aside, see you kill someone and you get away with it, they will lower your reputation every day until you get rid of them. If your reputation is too low, Senpai won't accept your confession. Said witnesses are also likely to post incriminating proof of your actions on social media, making it easy for the police to pin the blame on you.
 * Love Makes You Crazy: In Yandere-chan's case at least, though it's up in the air whether her craziness was always beneath the surface.
 * Make It Look Like an Accident: If you poison someone's food, it is assumed that the person choked on his or her food, as long as you don't try to dispose of the body.
 * Manipulative Bitch: You can play various people like pawns without them ever really noticing your machinations.
 * Mood Dissonance: Having a high-atmosphere school (and keeping it that way) even while Yandere-chan does her sinister deeds can come across as this.
 * Murder the Hypotenuse: It wouldn't be complete without this. Perhaps surprisingly, you don't need to kill your rivals to eliminate them. Also in the lore.
 * Necessary Evil: It's implied that Yandere-chan sees herself as this, given how she's willing to do heinous acts supposedly for the good of Senpai.
 * OOC Is Serious Business: The photography club members like to goof around and have fun, and in-fact joined the club for that reason. But when the atmosphere is low, they don't feel like having fun and get more serious. And when the atmosphere is very low, they actively look for evidence.
 * Origin Story: Yandere-chan's Childhood, which as the title suggests, covers her Dark and Troubled Past.
 * Pacifist Run: It's perfectly doable for Yandere-chan in the final game to remove her targets without actually killing any of them. Even if that involves torturing, lying and manipulating her way through.
 * Panty Shot: Yandere-chan can do this in-game, sending her incriminating pics to Info-chan.
 * Parental Abandonment: Yandere-chan's parents are nowhere to be found. It's temporary (story wise) because they're on business in America. In practice they are going to be gone for pretty much if not flat out the entire game.
 * Police Are Useless: Subverted. The police would suspect and arrest Yandere-chan if there's too much evidence implicating her out in the open. Neither can she kill any policeman who arrives to investigate.
 * Reality Ensues: Trying kill a teacher without the proper method or the right skills is a guaranteed way for Yandere-chan to have her ass apprehended. Likewise, simply going about murdering everyone on sight won't just send your sanity down rock-bottom, but would also make the game a lot more difficult.
 * A low-atmosphere school would not only look suitably grim and cloudy, but would also behave as one would expect from having several visible deaths happen in the same place. Students and teachers alike would be a lot more frightened, serious and worried, all but erasing any High School hijinks. And if Yandere-chan has low-reputation, it becomes significantly harder for her to escape suspicion as well.
 * The setting itself is rife with this. The default-atmosphere school may look straight out of a classic Dating Sim or any High School drama anime, but some of the students' backgrounds are anything but perky or cliched.
 * Leaving too much evidence (or too many witnesses) out in the open is guaranteed to send the police right after Yandere-chan.
 * There's a chance that anyone with a phone who witnesses Yandere-chan kill someone may take pictures of the crime and post them all over social media, making it all the easier for the police to go after her.
 * The Rival: Yandere-chan sees many rivals standing between her and Senpai.
 * Romance Sidequest: Averted. That's not the point of the game, according to Word of God.


 * Sanity Slippage: If you let your sanity go too low, Yandere-chan begins to visibly twitch and lunge about like a deranged killer.
 * Scary Shiny Glasses: Info-chan.
 * Screw This, I'm Outta Here: The lore reveals
 * Stalker with a Crush: Yandere-chan has a rather deep obsession with Senpai, to the point of having a full-fledged shrine on her bedside dedicated to him. Whether she can be blatant about that or mask it as much as possible is up to you.
 * Teens Are Monsters: Yandere-chan is definitely one, as much as she denies it.
 * Torture Cellar: The best way to describe the basement of Yandere-chan's house, as this is where she can drag her live captive and do whatever she wants with said prisoner.
 * Uncanny Valley: If you do the occult club ritual and go through the portal one of the three other creatures there is a humanoid with a deformed head, a very dark hole or something where the genitalia should be, and has arms that stop at the elbows (at the latest).
 * Video Game Cruelty Potential: There's no shortage of ways to kill, torture and generally make the lives of others feel like hell.
 * Video Game Cruelty Punishment: Go too far however, and the consequences of Yandere-chan's openly deranged antics become very evident, making the game nigh difficult to finish. In addition, an insane Yandere-chan is also shown to be sloppier and messier with her kills.
 * Villain Protagonist: Technically, Yandere-chan. It is possible however for her to channel her sociopathic tendencies towards non-lethal, albeit insidious approaches.
 * Villain with Good Publicity: . Also, Yandere-chan, potentially.
 * What You Are in the Dark: Part of the challenge for Yandere-chan is how long she could keep it in the dark.
 * X-Ray Sparks‎‎: What happens when you trick someone into electrocuting him/herself. They actually die from this.
 * Yamato Nadeshiko: Ryoba Aishi, Yandere-chan's working mother, has the facade of a modern-day one.
 * Yandere: Duh.

Builds, Development Videos, YandereDev's Blog, and Explicit Possibilities
""Gee, you're right, green-haired girl. It's time for me to get back to what I'm good at... murdering schoolgirls in horrific ways.""
 * April Fools: YandereDev has a habit of doing a special video every April 4.
 * Audience Surrogate: Midori Gurin, aka "Question-chan," who occasionally pops up in development videos asking YandereDev questions. And likely to die by the end of said videos.
 * Blinding Bangs: The temporary club leaders.
 * Christmas Special: It's Beginning To Look A Lot Like Murder~
 * Creator Backlash: Subverted in this recent video. Although YandereDev sincerely thanks fans, supporters and volunteers, he nonetheless expresses frustration over email spam and "contributions" that don't really make the cut for the game.
 * Department of Redundancy: YandereDev was concerned that Yandere Simulator would be considered a joke game because of the title. Yandere Simulator was initially intended as a description and working title but has gained name recognition so it might stick around. As such, he is considering renaming the game to LoveSick Yandere Simulator. Which of course still contains "Yandere Simulator".
 * Dissonant Serenity: YandereDev talks about the gruesome and disturbing features of the game in a soothing voice.
 * During his first e-mail-related video:

""As you can see, our prisoner is no longer watching us as we move around the room, and she's no longer twitching either. This is because we have completely destroyed her mind. There are no traces of a human left inside of her. She's permanently broken, forever. ...Let's bring her to school!""
 * On his October 17th 2015 update video:

"(While eerie music is playing) "They exist purely so that you can test a gameplay feature. There is no more meaning to their existence. (Music stops) Oh, and by the way, [...]""
 * Grid Inventory: In his Hitman gameplay analysis video, YandereDev plans on changing the inventory system, and a grid based inventory system is something he is considering.
 * Hiatus: YandereDev occasionally takes breaks from developing the game, partly to find some needed rest and partly so he could play games like Metal Gear Solid V: The Phantom Pain.
 * Japanese Delinquents: "Bancho Mode", part of the Easter Eggs, gives Yandere-chan a Commissar Cap and arm-wrappings, what sukeban typically wear. There are also deliquents of the male and female variety among the students in the school, who also double as Boss in Mook Clothing.
 * Murder Ballad: It's Beginning To Look A Lot Like Murder
 * Murder-Suicide: In the Tsubasa o Kudasai Promo-concept video.
 * Musical Episode: Senpai Notice Me: A Yandere Simulator Musical, by Random Encounters (Web Video), done with YandereDev's support.
 * Nothing Is Scarier: The SNAP option in every game over screen. At this point it remains a placeholder, but what that could entail is best left to the imagination.
 * Obvious Beta: The game is still very much a work-in-progress and YandereDev makes it clear with each update that there are several features and improvements yet to be implemented. In fact, certain elements like weapons inexplicably out on display in front of the school are the result of the build-in-progress being in debug mode.
 * Among the most obvious examples are the club leaders that are just place holders, introduced in the Febuary 1st 2016 update. YandereDev out right stated that "these vacant, empty, hollow husks" are place holders and won't react to murders that happen right in front of them. Furthermore they are all identical and are completely devoid of any personality. All they do is let you join their respective club.


 * One Man Party: Not quite this, but YandereDev is pretty much making the game by himself. Albeit with the help of friends and amateur voice actors.
 * The July 2017 development update video reveals that he's received the help of among others, tinyBuild, the developers also responsible for Hello, Neighbor.
 * Rule 63: The Yandere Simulator Male Rival Introduction Video.
 * Shout-Out: There are quite a few over the various builds.
 * One easter egg turns Yandere-chan into a female Big Boss, based on his appearance in Metal Gear Solid V: The Phantom Pain. Complete with a mechanical red arm and Mike Oldfield's Nuclear in the background.
 * Another turns almost every other NPC into Titans.
 * In more recent builds, an easter egg turning Yandere-chan into the homicidal protagonist of Hatred has been added.
 * For Halloween 2015, YandereDev introduced Yanvania: Senpai of the Night as a playable minigame. As an added touch, it's a rather faithful homage to Castlevania to boot.
 * Also found in recent builds is a mode that turns Yandere-chan into a Magical Girl, which adds even more Mood Dissonance as she magically kills everyone around her.
 * The March 2016 update video reveals that the incinerator used in the school is modelled after the one in the manga/anime series Prison School.
 * Sincerest Form of Flattery: YandereDev is frank about how he gained inspiration for various elements, gameplay features from Japanese visual novels, Dating Sims, and even Metal Gear. The latter can be found particularly in the emphasis on stealth.
 * It's also mentioned in an April 2016 video how he's also getting a lot of inspiration from the Hitman series, though is consciously making an effort not to simply rip off Agent 47.
 * Soundtrack Dissonance: Used in this promo concept (meant to be fully produced) where Yandere-chan kills a girl, then Senpai and then herself, synced to the Japanese folk song "Tsubasa o Kudasai."
 * Yandere-chan even syncs her stabs to the song.
 * Suspiciously Specific Denial:
 * Yandere-chan is not well versed in murder.
 * The February 21, 2016's The Totally Normal Update was totally normal. Absolutely nothing special related to the occult club. So don't get the wrong idea. Baka!
 * Yakuza: An August 2017 video brings up the possibility of Yandere-chan being able get in touch with a Yakuza contact through his delinquent brother in school. Said Yakuza contact would act as a dark mirror to Info-chan, allowing access to illegal weapons, hard drugs and other services beyond the reach of even Info-chan's capabilities.

Yanvania: Senpai of the Night

 * Affectionate Parody: of Castlevania: Symphony of the Night.
 * Shout-Out: One famous cutscene from the game is recreated, with "Senpai" replacing "man".
