The Duke employs a ruthless method to break the will of captured War Maidens by utilizing their power rings to subject them to the "Torment of the Flesh," a state of overwhelming sexual pleasure. Through this process, he corrupts the proud Valkyries and seduces others, including Fafnir and Fenrir, ensuring their total submission and the erosion of their purity.
After enduring relentless torture and betrayal by the humans they sought to protect, the War Maidens Ariya, Reiya, and Hildegard reach their breaking point. Amidst the chaos of a lunar eclipse and the abandonment of their god, their pride and purity are shattered. Overcome by despair and awakened desires, the three women renounce their former lives to become "War Maidens of Darkness," pledging their absolute submission to the demon Duke.
