Betrayal is a non-lethal elimination method in Yandere Simulator.
In the Schemes menu, the description is: "This scheme will end with your rival being betrayed."
Gameplay
This elimination method will start the same way as befriending a rival. (Performing a task for Osana, listening to her rooftop conversation, help her with her problem, and then asking her to meet Ayano.)
Betraying Kokona (Debug builds)
During the cutscene, the player will walk behind Kokona when her back is turned. The screen will shake and become distorted in color with the option "Eliminate" appearing next to Kokona. This option will only be available for a few seconds. If the player misses this opportunity, Kokona will only be befriended, instead of being betrayed.
When F is pressed, the screen will fade to black with Kokona screaming in shock. If the player goes down to their basement the next day, Kokona will be tied to a chair. In the future, this scene will be a cutscene instead.[1]
Betraying Osana
During the cutscene that plays between Ayano and Osana. In it, the player decides if they should give Osana normal or drugged tea. This option will only be available for a few seconds. If the player misses this opportunity, Osana will only be befriended, instead of being betrayed.
When Q is pressed, Ayano will give Osana the drugged tea. She starts getting sleepy, and Ayano smiles at her before she falls asleep. A cutscene will then play with Osana in the basement. If the player goes down to their basement the next day, Osana will be tied to a chair.
