The story of a young girl, Y/n. Who is born into a society where the world is split into two teams. Hunters. And Prey.. In this world, at the age of 18, you get a mark which basically determines your whole life. The Blue Skull: This means your a hunter, it is your job to hunt, and kill the prey. The Red Cross. This means your a prey, if you get this mark. Then your already dead. Your best interest would be to lay low for the rest of your life. Much like the rest of her family, Y/n is a hunter. Although she'd rather not go around killing innocent people, this was a good thing, right? Not being a prey? Or so she thought.
