Yandere is a simulator, but it is mission mode. You can play the story in 202x and 1989. Create your own story and your own plot. You can be Ayano, Ryoba, or your character. You can be a Yakuza mercenary. The most important thing at the beginning is to choose a victim and your own rules for the game.

To start the game, set a goal, for example: "Victim: Ayano Aishi. Kill with an attack. Burn the corpse. Don't get caught on cameras or go through a metal detector. Yakuza Mod: on"

But this is not necessary. You can make your own rules and your own game. Have a good time
