Saiko No Sutoka

Game description:

The main character is unlucky enough to become a love object of a crazy yandere girl called Saiko. As you can understand from her name, Saiko is actually a psycho and she wants to kill you. Yandere girl’s love easily turns into hate, so be careful. She is following you around the school, in the dark corridors and classrooms, and you need to find your way out of here before this lady takes your breath away (literally). Do your best to survive the horrible adventure with a crazy girl in love.
