Yandere Simulator is an upcoming stealth action video game currently in development by YandereDev and to be published by tinyBuild Games.[1][2] The game centers upon an obsessively lovesick schoolgirl named Ayano Aishi, also known as "Yandere-chan" after the Japanese term "yandere", who has taken it upon herself to eliminate anyone she believes is monopolizing her crush's attention.[3] Over the course of ten weeks, Ayano will eliminate ten different rivals.

Normal Yandere-chan (above) and insane Yandere-chan (below). After killing people, Yandere-chan will look disturbed, with blood-splattered clothes. The graphics and background music will become more thrilling.

Players control Ayano Aishi[4] (Yandere-chan), a Japanese schoolgirl who has developed a crush on a fellow student when she bumped into the boy currently named Taro Yamada (or a girl named Taeko Yamada),[5] nicknamed "Senpai".[6] Over the course of ten weeks, ten[7] other students develop crushes on Senpai, and Ayano must prevent them from confessing their love to him.

Due to her "yandere" nature, this can be accomplished by the player through a diverse array of methods, currently including drowning, electrocution, poisoning, homicide, kidnapping, faked death, frameup, gossip, incited suicide, murder–suicide due to torture, expulsion, befriending, betrayal, burning, crushing, and matchmaking. Throughout the game, Ayano can receive aid from an information broker calling herself "Info-chan", who can provide her with services such as weapons, plans, items, or other favors in exchange for panty shots.

Ayano must also avoid being witnessed while performing criminal activities, or suffer penalties ranging from a loss in reputation that makes it harder for other students to trust her, to diminishing sanity that discourages Senpai and hinders ability to carefully carry out crime, to an immediate game over.[8] Murdering students will result in penalties to "School Atmosphere", which alters NPC behavior to become more suspicious and riddled with anxiety, demonstrated by actions such as locking their lockers.[9] During this time, she can join school clubs and attend classes to receive additional abilities such as easy access to weapons, increase abilities to avoid suspicion or easy access to other items.

Currently, in this state of development, Yandere Simulator is a playable Debug Sandbox Build. This means that not all features are currently implemented. The final game will contain six modes:[10] Story Mode, the base game; 1980s Mode, a prequel to the base game; Endless Mode, a never-ending version of the base game; Custom Mode, a customizable version of the base game; Pose Mode, in which players may pose their favorite characters; and Mission Mode, in which Ayano completes missions for Info-chan.


YandereDev (Alex[11]) is an independent game developer in California and has worked at a video game company for three years. In April 2014, YandereDev pitched the idea for Yandere Simulator on 4chan,[12] where it got a lot of positive feedback, so he decided to start developing it.[13] It is a social stealth game that borrows elements from the Hitman series of video games, but also contains "school simulation" gameplay and other elements that seek to make it quite different.[14]

Development for Yandere Simulator began in 2014, with YandereDev releasing test builds of the game for debugging purposes.[15] He has regularly released updates that add elements to the game, such as the ability to poison, electrocute, and drown rivals, befriend other schoolgirls, small mini games, a town the player can bike around in, and more.[16][17]

On 1 March 2017, YandereDev announced a partnership with tinyBuild Games that would help him with polishing and promoting the game.[18][19]
