The player character in 'Yandere Simulator' is a schoolgirl named Yandere-chan. 'Yandere' is a Japanese term that refers to a person who is apparently loving and friendly but, under the right circumstances -- usually when their love expectations are not met, -- becomes extremely violent. Well, Yandere-chan has fallen for a classmate, but she's too shy to reveal her true feelings. What's her plan, then? Boycotting his love life, obviously! If any other schoolgirl comes near Senpai, Yandere-chan will make her 'disappear' forever...
