In the earliest days of mankind, before humans could establish kingdoms and laws, demons ruled the world with near absolute power. Though all were cruel and terrible, there were none crueler than the demon, Josephine.

In your past life, you were just one of many soldiers, born into a war that long preceded you. A face that no one would remember. A pawn who held no higher title. A soul who wouldn't be mourned.

During your final days in the war, you and Josephine shared a battlefield. By some chance, whether influenced by a divine force or just sheer luck, you happened to strike the final blow on the she-demon. As she fell, she shrieked a promise of revenge, a vow to bring your end in the next life. Despite your victory over her, you never lived to see the next day.
