A human woman wakes up in a dark room, all she can barely hear is chanting and when she fully wakes up, she is terrified at what she sees. Her nightmare starts that night, but someone saves her and promises she will be safe with their dear friend, but the only problem is she's a human and she has to stay in a world only meant for sinners. How will she survive, and who is this friend the person who saved her from being sacrificed? And why does she feel like she knows this demon who she'll be living with?
