Its 2088, the yandere virus has infected many woman across the world. It makes then more beautiful, stronger, faster, and smarter but also makes them insane for love

Men has low chance of becoming yanderes but they are often more dangerous

Most of the world is in constant chaos

Your currently in a ruined city

Hiding from the yanderes

You tune into a radio

"All survivors please head to town hall for evacuation"

You immediately tell from the tone of insanity that it's a trap.
