Ariya, the powerful Blue Sky war maiden, is captured by the sadistic Duke and betrayed by her comrade, Reia. Stripped of her divine powers and subjected to relentless sexual corruption and humiliation, Ariya's pride is shattered. As she succumbs to the demonic influence, the once-noble Valkyrie falls from grace, joining Reia in their shared submission to the reign of darkness.
Ariya is subjected to psychological and physical torment as the once-proud Lady Hilda is stripped of her powers and forced to help break her spirit. Through systemic degradation and forced corruption, both war maidens fall from grace and become slaves to the Master. Months later, a pregnant Hilda remains trapped in a cycle of abuse, bearing a demonic child while the Duke grows bored of his conquests.
Captured and broken by the demon king's forces, the War Maidens struggle with their fading honor. While Hild is tormented by the now-corrupted Freya and Skuld, Ariya recalls her own desperate attempt to shield her sisters from Duke's cruelty, which ultimately led to her own submission. A year later, the once-proud warriors have completely succumbed to their lust, transforming into mindless pleasure slaves for their demonic masters.
