Origin
Japan
Mai Waifu, whose real name is Mai Wakahara, is one of the female students that currently attends Akademi High School. A young woman who is pursuing an "anime aesthetic". To achieve this unusual goal, she never cuts her hair, wears special contact lenses, and asks people to refer to her by a nickname inspired by otaku culture. In her previous description, it was stated that she "has sworn her heart to an independent game developer living overseas", and "prefers to spend her time alone, daydreaming about her loved one". In her description, it was also stated that she is described as "deredere" by her admirers, so most likely that would be her attitude towards him. Mai has probably good relationships with Gema Taku, Pippi Osu, Ryuto Ippongo and Midori Gurin, since she spends most of her time in routine with them.
Yandere Simulator
Yandere Simulator is a stealth game about stalking a boy and secretly eliminating any girl who seems interested in him, while maintaining the image of an innocent schoolgirl. The game is currently under development, and a free debug sandbox build is available from the developer's official blog and website. The protagonist of the game is a high school student known as Yandere-chan who has fallen in love with an upperclassman known as Senpai. Yandere-chan cannot bear the thought of Senpai in another girl's arms, but she is too shy to confess her love to him, so she must resort to sabotaging his love life from the shadows. Once every week, a new rival girl will fall in love with Senpai. Each rival must be eliminated within 5 days, or else she will confess her love to Senpai, which will result in a Game Over. If Yandere-chan is arrested, expelled, or obtains a bad reputation, the result is an immediate Game Over. Rivals can be eliminated with lethal methods such as poisoning and electrocution, or eliminated with non-lethal methods such as kidnapping or matchmaking with other NPCs.
