Parome reigned as Maoh Queen and estranged wife of the Maoh King, ruler of the Genma tribe on a post-apocalyptic Earth. Obsessed with siring a powerful heir, her husband rejected her, believing any child between them would be weak. He pursued conception with human females instead. This rejection ignited Parome's jealousy and resentment, driving her to spy on the targeted human women, often dispatching her winged eyeball minion Earie to observe them.

When the Maoh King fathered twin sons, Loof and Jin, with the human Non, Parome was forced to raise Loof in the castle while Jin stayed with his mother. She subjected Loof to constant abuse and mistreatment, explicitly refusing to acknowledge him as her son. Her hatred extended to Non, whom she saw as a rival. After the Maoh King expressed a desire to see Non again, Parome ordered her assassination to eliminate the threat.

When Loof transformed unexpectedly into a human, losing his Genma traits, he was stripped of his princely status and banished. Parome seized the opportunity to pursue his execution, a plan her husband mockingly endorsed while taunting her over her jealousy.

Consumed by bitterness over her husband's infidelity and dismissive attitude, Parome plotted to overthrow him. She initially prayed to the Great Genma to cure his obsession but ultimately resolved to assassinate him and seize sole control of the Genma-ruled wasteland. Her schemes intensified after Loof and Jin united with their half-siblings to storm the Genma castle. During the assault, Parome killed several of the Maoh King's other hybrid children. She was later impaled by Ran, a human woman temporarily possessed by the Great Genma King. Mortally wounded, Parome retaliated by stabbing her husband through the chest. He counterattacked, fatally stabbing her in return. Both disintegrated into dust shortly after the twins were cast into a time portal.
