YandereDev, whose real name is Alex,[1] is a 32-year-old independent American game developer who resides in California. He was born on June 30,[2] 1988.[3] He worked for a video game company for three years prior to the creation of Yandere Simulator, then left to pursue his dream of becoming an indie game developer. He has worked on five console games and five mobile games for an unknown company. [4]

Between 2013 and 2014, YandereDev produced several game prototypes, though none of them became popular. In March of 2014, he pitched the idea of a "school-girl serial killer simulator" in a forum post. The idea was met with a very positive reception, so he began working on the game.[5]

Since the beginning of Yandere Simulator's development, he has created eight simple 'joke' games following the beginning of development. On April 16th, 2014 he released Yandere Clicker; on April Fools' 2015, he released Super Yandere 64 and Kuudere Simulator; on April Fools', 2016 he released Kuudere Simulator 2; on April 10th, 2016 he released Burning Love; on the Halloween of 2016, he released Yanderetale; on April Fools' 2017 he released Kuudere Simulator 3, and on the Halloween of 2017 he released Midori Forest.

YandereDev has also created two in-game video games: Yanvania: Senpai of the Night, which can be activated during Pippi Osu's task, and Magical Girl Pretty Miyuki. These games can be played on Ayano's gaming console in her room.

He also mentioned a "true love" project that he wanted to make. However, when he pitched it, it received a lot of negative criticism.[6]


Inspiration to create video games: Around 15 years ago, YandereDev used to design simple video games by scribbling characters and ideas. He also tried programs such as RPG Maker but never took it seriously. He eventually became more serious about making games in 2008.[7]

YandereDev was truly inspired to make games after playing a game called lji, which was developed by a man named Daniel Remar. The game was made by one man, so YandereDev felt like it was possible for him to do the same. It sparked his interest in learning how to program. [8]

Inspiration for Yandere Simulator: Before working on Yandere Simulator, YandereDev tried to develop other prototype games, but there was a lack of 3D models that he required. While searching for models, YandereDev saw a very inexpensive schoolgirl character model for sale on the Unity Asset Store. He asked a friend what type of game he would develop if he had to use that model for the protagonist. His friend suggested a "juvenile delinquent" simulator. YandereDev enjoys pushing concepts to the farthest extreme, so he wondered, "Why stop at a delinquent? Why not make her a serial killer?" From there, he pitched the idea for a "yandere simulator" to a high-traffic message board. A lot of people commented on the idea and suggested some really cool-sounding features. The hypothetical game started to sound really fun, and it seemed like people were genuinely interested in the idea, so YandereDev decided it would be worthwhile to actually develop the game.[9][10]


YandereDev is known for working twelve hours a day and gave on January 8, 2016 that he has used the same scale to upload the updates since last year. YandereDev usually attempts to upload new updates on the first and fifteenth or each month. He works mainly only on the game, with the help of a few volunteers.

He initially felt insecure about his appearance and does not like the way he looks, but eventually did a face-reveal.


As YandereDev has stated that he is insecure about his appearance and does not like the way he looks,[11] having once stated that he didn't want photos of him in the past because he had "nasty dark eye circles", he usually represents himself in videos through anime-style artworks of a persona. In older videos, he used Ayano Aishi, who is also his avatar, to represent himself.

YandereDev's persona is clearly based off aspects of his real-life appearance: A man with black hair and brown eyes. However, unlike his real-life appearance, his persona is not usually depicted with glasses.

Despite usually refraining from showing photos of himself, he has shown his face on Twitch livestreams, and during his visit to Anime Expo 2016, he allowed fans to take photos with him. Since then, there have been several public pictures featuring him on his blog.[12]


YandereDev usually wakes up at 8:00 AM and starts his day with a shower.[13] If he oversleeps, he works until 2:30 AM.[14] On that note, he usually gets about six hours of sleep each night.[15] While working, he usually listens to anime soundtracks, video game soundtracks, Vocaloid music, podcasts, or Let's Players commentating.[16] YandereDev has stated that he practically has no free time.[17]

As of December 2015, YandereDev was so burnt out from working that he changed his routine so that he only works eight hours a day, only sometimes working on the game for twelve hours. Any excess time he has now is spent live streaming games.[18] He used to work twelve hours a day in total, with five minute breaks every hour.[19]

In addition, he has also stated that he may not be able to update the game every two weeks anymore, due to the fact that almost all of the minor features that would only take two weeks to implement have already been implemented.[20]
