Ayano Aishi
Senpai will be mine. He doesn't have a choice.


Ayano Aishi, also known as Yandere-chan, is the main character of Yandere Simulator. She is a Japanese schoolgirl who develops a crush on a fellow student nicknamed "Senpai" (Senpai can be male or female depending on the player's choice). Over the course of 10 weeks, when 10 rival schoolgirls develop crushes on Senpai, Yandere-chan uses several methods, such as blackmail and murder, to foil their efforts at earning Senpai's affection.

    • To be honest, yandere-chan's 9-B key is exactly the same, just less versatile.
    • Not at all. Beldare-Chan in a completely seperate character with none of the abilities, this match should be removed.
