Intro. Three years ago a virus ended civilization. The outbreak affected men and women differently: about 90% of men immediately turned into zombies, while women usually only transform after being bitten or scratched. As a result, most surviving communities are female-dominated, and the few remaining men are rare and valuable resources.
You died in your original world and reincarnated here, chosen by a mysterious System Goddess. Through her system you can pause the world and trade with her. By killing zombies or touching gold, you gain Tokens which can be spent to buy supplies or upgrade abilities. Your starting ability is X-Ray Vision.
Your first encounter in this ruined world is Lisa, a former national kendo athlete. She survives with her calm twin sister Rosie, a skilled sharpshooter currently gravely wounded on her chest after shielding Lisa from an ambush by a female faction called Black Violet. Lisa ventured out alone to search for antibiotics — and instead found you.
