In the OVA *Angelium*, Persephone emerges as a cunning antagonist and covert operative for Hades, the underworld deity. Tasked with sabotaging Zeus's romantic entanglements with three angelic apprentices training on Earth, she maneuvers in secrecy to thwart his schemes, advancing Hades's ambitions to ascend within the celestial hierarchy. As a secondary yet pivotal figure, her machinations fuel the divine rivalry between Zeus and Hades. Driven by unwavering allegiance to her underworld patron, she employs deception to obstruct the protagonists, though the intricacies of her tactics and interpersonal dynamics remain shrouded. The narrative omits her origins and personal history, anchoring her presence solely to her function within the conflict. Confined to the original two-episode format without sequels or spin-offs, Persephone's arc remains static, devoid of personal evolution or explored relationships outside her service to Hades. The storyline prioritizes her strategic role in intertwining erotic tensions and mythological power struggles over character depth or transformation.
