Olivia, destined for death at the Gate to the Underworld, defies fate when the death god Zed spares her life and raises her as his own. Armed with a crimson jewel, a cryptic letter, and a foreboding black sword left by Zed's departure, she embarks on a journey to the battlefield. Amidst a longstanding conflict between the Kingdom and Imperial forces, where victory remains elusive after years of brutal warfare and mounting casualties, Olivia emerges as a beacon of hope for the Kingdom. Concealing a lethal prowess behind her innocent facade, the girl nurtured in bloodshed by death itself becomes the harrowing force that will tip the scales of war, painting a path of carnage with severed heads, dismembered limbs, and decaying bodies in her wake.
