After being victim of a brutal ghoul attack by none other than Big Madam herself, Emi's life changes completely. She goes from playing with dolls to playing with knives. From candy rewards, to 'good girl points'. From a comfy bed to a cold cell. The girl who could never even dare to hurt a fly now has to kill to stay alive. ~ Being a scrapper made Suzuya a heartless killer. He thought nothing of it, the only thing that mattered was pleasing Big Madam. The flashier the kill, the more good boy points he earned. Life was simple but hard at the same time. He killed to stay alive. He killed to make his Mama happy. He killed because it was fun. But what happens when a girl he had never seen before moves to the cell right in front of his? And worse, becomes Big Madam's new pet? There can only be one scrapper, and that scrapper was him. He would not let that be taken away from him. But as time passes he begins to wonder; does he really want to kill the girl?
