Alexander Mahan (born June 30, 1988 (1988-06-30) [age 28]) known on YouTube as YandereDev is an independent game developer from California. He worked at a video game company prior of the creation of Yandere Simulator, then left to pursue his dream of becoming an indie game developer. His first known indie game was "Lunar Scythe" which is postponed by now. He has created five console games and five mobile games he contributed to this company.


YandereDev is best known for being incredibly hard-working. He works twelve hours a day and as of January 8th, 2016 YandereDev states that he has been using the same exact update schedule for the past year. YandereDev always tries to get his builds out on time. He even mainly works on the game alone, with help from volunteers.

He is sarcastic, which really shows when answering some Twitter posts. He is like pissed off towards people sometimes because he cannot tolerate anyone like that, even if they are a fan of Yandere Simulator. YandereDev created Midori Gurin solely for the purpose of ridiculing people who send him stupid emails. On the video Yandere Simulator's BIGGEST Problem, YandereDev almost make Midori cry when YandereDev wanted to tell her that stop emailing him. Midori returns in the video, The Gaming Club where Midori is crying and she will attempt to kill YandereDev with a knife and just Before that, YandereDev tells to Midori that the Gaming Club is finished implementing it.

He is insecure about his appearance as he does not like the way he looks due to the fact that he did some horrible things in the past before he was known as "YandereDev", but YandereDev will eventually reveal his face, sometime before the Kickstarter, so that he does not seem shady when trying to hide his identity.
