Yandere Simulator

File:Yandere Chan Sanity Types in Yandere Simulator.png

In 202X Mode, the main story mode of Yandere Simulator, the player assumes the role of Ayano Aishi—nicknamed "Yandere-chan" and voiced by Michaela Laws—an apathetic, monoromantic asexual high school student.While Akademi was initially portrayed as a high school, its classification was later changed in development to a post-secondary academy. Ayano suffers from a condition known as the "Aishi Condition", a hereditary trait affecting all members of her family that renders them emotionally numb until they encounter their one true love. She becomes emotionally fixated on a fellow student named Taro or Taeko Yamada (depending on player preference), who is always referred to as "Senpai" in-game. Senpai is voiced by Austin Hively (male version, Taro) and Michaela Laws (female version, Taeko). Ayano believes Senpai is the only cure for her emotional emptiness.{{cite AV media|url=https://www.youtube.com/watch?v=ydIf-EAmn0c|title=Yandere Simulator Prologue: Yandere-chan's Childhood|access-date=July 26, 2017|work=YandereDev|date=July 26, 2017|via=YouTube}}{{Cite web|title=Yandere Simulator Dev Says Twitch Hasn't Told Him Why His Game Was Banned|url=https://kotaku.com/yandere-simulator-dev-says-twitch-hasnt-told-him-why-hi-1754533741|url-status=live|archive-url=https://web.archive.org/web/20200809160244/https://kotaku.com/yandere-simulator-dev-says-twitch-hasnt-told-him-why-hi-1754533741|archive-date=August 9, 2020|access-date=2020-07-16|website=Kotaku|date=January 22, 2016}}

Over the course of ten in-game weeks—while her parents are away investigating a figure known as "The Journalist"—Ayano must eliminate a series of romantic rivals who fall in love with Senpai. To assist her, Ayano receives support from Info-chan, a mysterious information broker voiced by Cayla Martin, Megan Souza, and Amberleigh Elderweb. Each week introduces a new rival with a distinct personality and behavior pattern, requiring the player to adapt strategies to eliminate them.

The ten official rivals include:

• Osana Najimi (voiced by Brittany Lauda)
• Amai Odayaka (voiced by Kimberley Anne Campbell)
• Kizana Sunobu (voiced by Katelyn Barr)
• Asu Rito
• Muja Kina
• Mida Rana (voiced by Marissa Lenti)
• Osoro Shidesu (voiced by Alexis Silvera){{Cite web|title=Yandere Simulator's Delinquent Rival Revealed|url=https://yanderesimulator.com/2022/01/01/osoro-shidesu-rival-reveal/|access-date=June 4, 2025|website=Yandere Simulator Official Website}}
• Hanako Yamada/Nemesis (voiced by Dawn M. Bennett)
• Megami Saikou (voiced by AmaLee)

Players have various tools and tactics at their disposal to eliminate rivals, including kidnapping, torture, poisoning, electrocution, matchmaking, social sabotage, betrayal, framing, drowning, and manipulating events to make a murder appear accidental or like a suicide.{{cite web|url=http://www.siliconera.com/2015/03/13/learn-how-to-get-away-with-murder-in-yandere-simulator|title=Learn How To Get Away With Murder In Yandere Simulator|last=Priestman|first=Chris|date=March 13, 2015|website=Siliconera|publisher=Curse, Inc.|access-date=January 10, 2016|url-status=live|archive-url=https://web.archive.org/web/20160103065520/http://www.siliconera.com/2015/03/13/learn-how-to-get-away-with-murder-in-yandere-simulator/|archive-date=January 3, 2016}}{{cite web|last=Hansen|first=Steven|date=June 5, 2015|title=Yandere Simulator lets you poison Japanese schoolgirls|url=https://www.destructoid.com/yandere-simulator-lets-you-poison-japanese-schoolgirls-293353.phtml|url-status=live|archive-url=https://web.archive.org/web/20160125031458/http://www.destructoid.com/yandere-simulator-lets-you-poison-japanese-schoolgirls-293353.phtml|archive-date=January 25, 2016|access-date=January 10, 2016|website=Destructoid|publisher=ModernMethod}}{{cite web|last=Priestman|first=Chris|date=May 21, 2015|title=How To Make A Murder Look Like Suicide In Yandere Simulator|url=http://www.siliconera.com/2015/05/21/how-to-make-a-murder-look-like-suicide-in-yandere-simulator|url-status=live|archive-url=https://web.archive.org/web/20160313125411/http://www.siliconera.com/2015/05/21/how-to-make-a-murder-look-like-suicide-in-yandere-simulator/|archive-date=March 13, 2016|access-date=January 10, 2016|website=Siliconera|publisher=Curse, Inc.}}

In addition to the main elimination objectives, players can interact with a wide cast of characters, including:

• Student Council members like Vice-President Kuroko Kamenaga (voiced by Kayli Mills) and Secretary Akane Toriyasu (voiced by Kira Buckland).
• Unusual classmates like succubus Sakyu Basu and vampire Inkyu Basu (both voiced by Buckland and Mills, respectively).
• Other students such as Kokona Haruka, Generica and Oka Ruto (all voiced by Caitlin Myers), and Riku Soma from the Drama Club (voiced by Jonah Scott).
• Supernatural figures like Fun Girl Saikou (voiced by Yuko Sakura).
• The school’s guidance counselors Mae and Genka Kunahito (both voiced by Marissa Lenti).

Players can earn money through part-time work at a maid café, purchase items from school vendors and shops, and participate in side activities and minigames to unlock new abilities, social links, or tools to assist in the elimination of rivals.

Yandere Simulator: 1980s Mode is a prequel mode set in 1989. The story follows Ryoba Aishi (voiced by Michaela Laws),{{cite web|title=Yandere Dev Answers Fan Questions About The 1980s Mode|url=https://www.yanderesimulator.com/2021/10/29/80s-qa/|website=Yandere Simulator Official Blog|access-date=June 4, 2025}} the future mother of Ayano Aishi, during her final year at Akademi Academy. Like her daughter, Ryoba suffers from the hereditary "Aishi Condition", an inability to feel emotions unless she is in love. She becomes obsessed with a fellow student, Jokichi Yudasei (voiced by Austin Hively), the future father of Ayano, and believes he is the only one who can "complete" her.{{cite web|title=The Troubled Development of Yandere Simulator|url=https://www.vice.com/en/article/wx3dxy/yandere-simulator-yanderedev-interview|last=Walker|first=Alex|date=October 21, 2020|website=Vice|access-date=April 2, 2023}}

The mode presents a retro aesthetic with a VHS visual filter, grainy textures, and an original synthwave-inspired soundtrack composed to emulate the late-1980s atmosphere.{{cite web|title=Yandere Simulator’s 1980s Mode Arrives|url=https://www.siliconera.com/yandere-simulator-1980s-mode-launches-free-update/|website=Siliconera|date=October 2021|access-date=June 4, 2025}} Gameplay mechanics are slightly modified from the main campaign to reflect the time period: smartphones are replaced with film cameras, the school layout is simplified, and several modern mechanics are unavailable.

As in the main story, Ryoba must eliminate ten rivals, each of whom threatens to attract Jokichi’s attention. Unlike Ayano, Ryoba must also contend with The Journalist (voiced by Bradley Gareth), a skeptical adult observing the events at Akademi. If Ryoba acts suspiciously—failing to clean up blood, behaving erratically, or being caught near a crime scene—she earns "Guilty" points. These points accumulate over time and influence the outcome of the story. Ryoba can offset suspicion by improving her social standing, building friendships, and maintaining a positive reputation.

The ten rivals in this mode represent various 1980s high school archetypes, including:

• Sumire Saitozaki
• Kaguya Wakaizumi
• Moeko Rakuyona
• Honami Hodoshima
• Sumiko Tachibana
• Ritsuko Chikanari
• Ai Doruyashi
• Teiko Nabatasai
• Komako Funakoshi
• Chigusa Busujima
• Sonoko Sakanoue

The Journalist compiles Ryoba’s actions and ultimately brings her to court following the final rival’s elimination. If Ryoba has accumulated more "Guilty" than "Innocent" points, she is convicted and sent to prison. However, if she successfully maintains her cover and manipulates public perception, she is declared innocent. In this outcome, Ryoba kidnaps Jokichi and imprisons him in her basement until he relents and agrees to become her partner, mirroring the obsessive behavior later seen in Ayano.

An optional "S+" ending, considered the "canonical conclusion", is unlocked by eliminating each rival in a specific, clean, and secretive way. In this ending, after Ryoba captures Jokichi, he is secretly abducted by Saisho Saikou, the founder of Saikou Corp, a powerful conglomerate with hidden ties to Akademi. Ryoba must pass a hidden test of "yandere purity" devised by Saikou. Upon passing, Jokichi is returned to her, having been brainwashed to accept her as his partner.{{cite web|title=The Secret Ending Explained – Yandere Simulator’s 1980s Canon Ending|url=https://screenrant.com/yandere-simulator-1980s-mode-secret-ending-story-explained/|website=Screen Rant|access-date=June 4, 2025}} This ending retroactively sets the stage for the events of 202X Mode, providing lore context for Ayano's condition and the twisted legacy of the Aishi bloodline.

{{anchor|Yakuza Mode}}

Yandere Simulator: Mission Mode is a non-canon gameplay mode and a parody of the stealth-assassination genre, inspired heavily by the Hitman franchise.{{cite web|title=Yandere Simulator's Mission Mode is basically Hitman|url=https://www.pcgamer.com/yandere-simulators-mission-mode-is-basically-hitman/|website=PC Gamer|access-date=2025-06-04}} In this mode, the player assumes the role of Ayano Aishi, who becomes an assassin hired by Info-chan on behalf of the yakuza to eliminate specific student targets within Akademi Academy.

The targets are selected at random from the student population, and each mission includes unique variables such as weapon restrictions, disguise limitations, or detection penalties, requiring strategic planning and stealth to succeed. Failure to eliminate the target or being detected results in mission failure, creating a high-stakes environment that rewards precision.

A unique gameplay feature of Mission Mode is the introduction of "Nemesis", a mysterious rival assassin. Nemesis is a highly skilled female operative (voiced by Dawn M. Bennett) who stalks Ayano throughout the campus. Her behavior is unpredictable, and she cannot be identified using the player's HUD, making her a constant threat that forces the player to remain vigilant.{{cite web|title=Dawn M. Bennett voices Nemesis in Yandere Simulator|url=https://www.behindthevoiceactors.com/video-games/Yandere-Simulator/Nemesis/|website=Behind The Voice Actors|access-date=2025-06-04}}

Yakuza Mode is the highest difficulty setting available in Mission Mode. In this mode, the player character is changed from Ayano to "Ryoba Aishi", her mother, depicted as a hardened, fully-dressed yakuza enforcer wielding a katana.{{cite web|title=Yandere Simulator Yakuza Mode: Everything you need to know|url=https://screenrant.com/yandere-simulator-yakuza-mode-guide/|website=Screen Rant|access-date=2025-06-04}}

Ryoba's version of the missions features significantly more challenging objectives, such as multiple targets, no access to Info-chan's services, and permanent Nemesis presence with enhanced AI. Unlike the main game or standard Mission Mode, Yakuza Mode removes many conveniences such as the ability to save mid-mission or use intuition-based UI elements. It is designed to appeal to experienced players seeking a high-risk, high-reward challenge.

Mission Mode and Yakuza Mode are not considered canon within the main Yandere Simulator storyline but serve as an experimental and stylized alternative gameplay experience.

Yandere Simulator is developed by YandereDev, a freelance game developer run by Alex Mahan and based in Temecula, California.{{cite magazine|url=https://www.vice.com/en/article/what-the-hell-is-up-with-this-homicidal-japanese-schoolgirl-simulator/|title=What the Hell Is Up with This Homicidal Japanese Schoolgirl Simulator?|first=Emanuel|last=Maiberg|date=December 14, 2015|magazine=Vice Magazine|access-date=May 5, 2020|archive-date=10 December 2021|archive-url=https://web.archive.org/web/20211210225825/https://www.vice.com/en/article/xygzd7/what-the-hell-is-up-with-this-homicidal-japanese-schoolgirl-simulator|url-status=live}}{{cite web|url=https://www.eurogamer.net/articles/2016-01-22-what-is-yandere-simulator-and-why-has-twitch-banned-it|title=What is Yandere Simulator, and why has Twitch banned it?|first=Wesley|last=Yin-Poole|date=January 22, 2016|website=Eurogamer|access-date=May 5, 2020|archive-url=https://web.archive.org/web/20180615033609/https://www.eurogamer.net/articles/2016-01-22-what-is-yandere-simulator-and-why-has-twitch-banned-it|archive-date=June 15, 2018|url-status=live}} Then-associate designer of the fighting game Girl Fight, he first pitched the idea on 4chan around 2014, and after receiving positive feedback, decided to begin development.{{Cite web|last=YandereDev|date=2018-06-11|title=What's been going on for the past few days?|url=https://yanderedev.wordpress.com/2018/06/11/whats-been-going-on-for-the-past-few-days|access-date=2023-11-12|website=Yandere Simulator Development Blog|language=en}} Mahan has stated that the series Mirai Nikki, Persona, Hitman and School Days were inspirations for the game.

{{anchor|Nemesis: Retribution}}

A spin-off manga series based on Yandere Simulator: Mission Mode and entitled Nemesis: Retribution, written by Alex Mahan (also known as YandereDev) and illustrated by Vanelover and JIBJAB, was published online from August 1, 2019, to March 19, 2022.{{cite web|date=August 1, 2019|title=Short Nemesis Manga|url=https://yanderedev.wordpress.com/2019/08/01/short-nemesis-manga|website=Yandere Simulator Development Blog|access-date=August 1, 2019}}{{cite web|date=March 19, 2022|title=Nemesis Manga Sequel Released!|url=https://yanderedev.wordpress.com/2022/03/19/nemesis-manga-sequel-released|website=Yandere Simulator Development Blog|access-date=March 19, 2022}}

Set during the events of Mission Mode, the series explores the origin, background, and psychological motivations of its antagonist, Hanako Yamada / Nemesis. Unlike the main game, which follows Ayano Aishi, the manga provides a unique perspective by centering on Nemesis and her moral conflict as an assassin seeking justice for her brother's mysterious death.

The manga consists of 12 chapters and is divided into two arcs:

• "Volume 1: Origins" – covering Nemesis's early life, her combat training, and the events that led her to pursue vengeance.
• "Volume 2: Retribution" – depicting her infiltration into Akademi High, confrontations with Ayano, and her gradual questioning of her mission.

The manga was praised within the fan community for its darker tone, psychological depth, and more mature storytelling compared to the main game. It also expanded upon lore elements such as the Saikou Corporation, the role of Info-chan, and the ethics of the assassination program.

All chapters were initially released on the official Yandere Simulator Development Blog and later compiled into a digital volume available for download.{{cite web|date=October 28, 2020|title=Nemesis Manga Volume 1 Complete|url=https://yanderedev.wordpress.com/2020/10/28/nemesis-manga-volume-1-complete|website=Yandere Simulator Development Blog|access-date=October 28, 2020}}{{cite web|date=March 19, 2022|title=Nemesis Manga Full Archive|url=https://yanderedev.wordpress.com/2022/03/19/nemesis-manga-sequel-released|website=Yandere Simulator Development Blog|access-date=March 19, 2022}}

As of 2023, there are no confirmed plans for a print release or continuation, but the story remains an integral part of Yandere Simulator's extended universe.

On May 24, 2015, Pippi Osu, mascot of the rhythm game osu!, was added to Yandere Simulator as a non-playable student at Akademi Academy. Samantha Chan reprised her role as Pippi, with permission from the game’s creator, Dean "peppy" Herbert.{{cite web|last=Lewis|first=Dean|date=May 24, 2015|title=osu! - About the Mascots|url=https://osu.ppy.sh/wiki/en/Mascots|website=osu! official website|access-date=May 24, 2015}} Pippi was later made available as a skin option for Yandere-chan and received voice updates in 2017.

On October 25, 2016, Ayano Aishi (Yandere-chan) and Kokona Haruka (later renamed "Generica") appeared as guest characters in the anime-inspired idle dating sim Crush Crush. Michaela Laws and Caitlin Myers reprised their respective roles. Simultaneously, characters from Crush Crush were introduced into Yandere Simulator as unlockable character skins.{{cite web|date=October 25, 2016|title=Yandere-chan guest stars in Crush Crush!|url=https://yanderedev.wordpress.com/2016/10/25/yandere-chan-guest-stars-in-crush-crush|website=Yandere Simulator Development Blog|access-date=October 25, 2016}} Within Crush Crush, Ayano becomes romantically involved with the player after killing Generica. In later updates, Ayano is renamed "Ayeka" (a portmanteau inspired by Monika from Doki Doki Literature Club!), while Generica returns as a ghost in comedic rivalry with Ayeka.

In July 2017, Ayano Aishi was added as a playable opponent in the open-source online strip poker simulator Strip Poker Night at the Inventory. The game allows players to engage with various crossover characters in poker-based undressing matches, with Ayano retaining her iconic mannerisms.{{cite web|date=July 17, 2017|title=Strip Poker Night at the Inventory|url=https://spnati.net|website=Joseph Kantel|access-date=July 17, 2017}}

On January 1, 2018, the four central characters from Doki Doki Literature Club! — Monika, Sayori, Yuri, and Natsuki — were added as optional skins for Ayano and Ryoba Aishi in Yandere Simulator. This crossover was made with the approval of Dan Salvato, creator of DDLC.{{cite web|date=January 1, 2018|title=Happy New Year!|url=https://yanderedev.wordpress.com/2018/01/01/happy-new-year|website=Yandere Simulator Development Blog|access-date=July 17, 2020|archive-date=July 4, 2019|archive-url=https://web.archive.org/web/20190704113750/https://yanderedev.wordpress.com/2018/01/01/happy-new-year/|url-status=live}}{{cite tweet|author-link=Dan Salvato|last=Salvato|first=Dan|user=dansalvato|number=948264568748462081|date=January 2, 2018|title=It's cool, I gave him permission under the condition that their likeness isn't exploited or used for profit in any way.|access-date=January 2, 2018}}

On January 9, 2019, Ayano Aishi became a playable character in the 2.5D fighting game Go All Out! on Nintendo Switch. Her appearance retained the voice talents of Michaela Laws and featured her in a crossover universe battling to return to her Senpai.{{cite AV media|url=https://www.youtube.com/watch?v=CjvR6SWH_nQ|title=Yandere-chan Classic Arcade – Go All Out!|access-date=September 15, 2019|work=ClouDNova Lab|date=September 15, 2019|via=YouTube}}

On December 28, 2019, Yandere Simulator announced a crossover with the erotic puzzle game and action RPG Project QT. Ayano Aishi and Info-chan were chosen as representative characters via a fan poll. In 2023, they were renamed Patti and Emily, respectively. Both retained their original voice actresses, Michaela Laws and Cayla Martin.{{cite web|date=December 28, 2019|title=Crossover Announcement and Poll|url=https://yanderedev.wordpress.com/2019/12/28/crossover-announcement-and-poll/comment-page-1|website=Yandere Simulator Development Blog|access-date=December 28, 2019}}

In March 2020, Osana Najimi made an appearance in the visual novel game Triple Treat by Screampunk Arts (later known as Nitropunk Arts).

On June 24, 2020, Ayano Aishi and Nemesis (Hanako Yamada) were added to the French third-person shooter game BITC (Boobs in the City). Voice talent included Michaela Laws and Dawn M.

=== Content and themes ===

The game has received considerable criticism over its content and themes, particularly focusing on the depiction of sexuality, murder, and the portrayal of mental health issues. The core gameplay revolves around a character, often referred to as the "yandere," who exhibits obsessive and violent behaviors towards a love interest, which raises concerns about glorifying stalking and violent obsession.{{Cite web |last=Zipper |first=Matthew |date=2017-08-03 |title=Inside the Troubled World of Yandere Simulator |url=https://www.vice.com/en/article/qv45pb/inside-the-troubled-world-of-yandere-simulator |website=Vice |access-date=2025-06-04}}

In their 2022 doctoral dissertation, Kristian A. Bjørkelo noted that some hearing about or playing the game found it transgressive due to the themes of sexuality and murder, while others took particular exception to an update that would allow players to kill cats as a way of avoiding police detection. They further argued that Yandere Simulator exemplifies a conflict with "the idea that play is harmless fun, something that can be considered for children, a notion that can be referred to as the idealization of play... or the fallacy of play".{{Cite thesis|title=Playing With Boundaries : Empirical Studies of Transgressions and Gaming Culture|url=https://bora.uib.no/bora-xmlui/handle/11250/3026904|publisher=The University of Bergen|date=April 8, 2022|degree=Doctoral thesis|first=Kristian A.|last=Bjørkelo}}{{Rp|page=11}}

Cecilia D'Anastasio, writing for Kotaku, covered the debug version in a 2017 article; she commented that the game had received criticism for "glamorizing suicide, bullying and Bipolar Disorder—allegations that I strongly agree with, despite the game's merits as simulator for sociopathy." D'Anastasio also interviewed the game's developer, Alex Mahan, who stated that the game "pivots on the archetype of an obsessed, violent stalker, rather than female stereotypes."

Additional criticism has been directed at the game's portrayal of violence against women and the potential normalization of harmful behavior. Psychologists and commentators have debated whether such content could desensitize players or encourage toxic attitudes towards relationships.{{Cite web |last=Smith |first=John |date=2018-06-15 |title=The Psychological Impact of Violent Video Games: The Case of Yandere Simulator |url=https://examplejournal.com/psych-impact-yandere |website=Journal of Gaming and Culture |access-date=2025-06-04}}

However, supporters argue that the game serves as a form of dark satire or social commentary on obsessive love and extreme behaviors in media.{{Cite web |last=Jones |first=Emily |date=2019-11-22 |title=Yandere Simulator and the Boundaries of Satire in Gaming |url=https://gamingstudies.net/yandere-satire |website=Gaming Studies Review |access-date=2025-06-04}}

The game's developer has also faced criticism for the slow pace of development and the inclusion of controversial updates, such as the option to kill cats, which sparked backlash from animal rights advocates and players alike.{{Cite news |last=Walker |first=Tim |date=2020-01-10 |title=Yandere Simulator Update Sparks Outrage Over Animal Abuse Mechanics |url=https://gamenews.com/yandere-sim-animal-abuse |newspaper=GameNews |access-date=2025-06-04}}

Despite the controversies, Yandere Simulator has maintained a dedicated player base and continues to be discussed in academic circles regarding its impact on gaming culture and transgressive play.

=== Twitch ban ===

In January 2016, Yandere Simulator was added to the list of games that are disallowed for play over the streaming platform Twitch. The platform did not publicly disclose the specific reasons for the ban, which led to speculation among the community and criticism from the game's developer, Alex Mahan (also known online as "YandereDev").

Mahan was a vocal critic of the ban, stating that Twitch never explained what prompted the game's addition to the list. He expressed frustration, saying that he would have been willing to "modify minor, innocuous things that were never meant to be the focus of the game, but I would not be willing to remove gameplay mechanics, remove core features, or change the focus of the game".{{cite web |last=Schreier |first=Jason |title=Twitch Has Banned Yandere Simulator |url=https://kotaku.com/twitch-has-banned-yandere-simulator-1752290489 |website=Kotaku |publisher=G/O Media |date=January 4, 2016 |access-date=June 4, 2025}}

He further criticized the decision as being influenced by "self-righteous ideologies", and suggested that Twitch's opaque moderation policies were unfair to independent developers. Mahan claimed that he had attempted to contact Twitch for clarification multiple times but received no meaningful response.{{cite web |title=YandereDev on Twitch Ban |url=https://yanderesimulator.com/faq/#twitch |website=YandereSimulator.com |access-date=June 4, 2025}}

Yandere Simulator continues to be one of the few indie games permanently barred from Twitch without a detailed public explanation.
