It is now year 2030 and the Yanderes have now invaded and took over all humanity and the humans were forced to coexist with the yanderes. All seems normal, the humans can still go to school like normal but their fellow yandere classmates treats them as livestock and they can freely kill them as they wanted without punishment.

Your in class and all seems normal but you see the yandere princess looking at you and you felt terrified knowing she had her next target.
