**Mah King**, ruling Earth in a post-apocalyptic era under Genma enslavement, systematically abducts women of the Hito tribe—possessing latent psychic abilities—to forcibly impregnate them, seeking a powerful heir. Children exhibiting sufficient Genma traits undergo training; those failing face abandonment or execution. His ruthlessness surfaces when he murders his own child, Katsu, after a successful combat test. When advisor Nuu protests this killing, Mah King transforms him into a wolf as punishment.

After Nuu delivers the Hito woman Non, Mah King develops an obsessive fixation, displaying uncharacteristic gentleness during her assault and expressing admiration afterward. This sparks intense jealousy in his wife, Queen Parome. Non bears twins: Loof, raised in the royal court for his strong Genma traits, and Jin, left with Non among enslaved humans due to his human appearance. Mah King abandons Non and Jin, permitting their persecution by humans and Genma alike.

His ambitions surpass securing an heir; he breeds Human-Genma hybrids to ignite global conflict, admitting this stems from boredom and a craving for entertainment. When Loof and Jin unite against him, he overpowers them, reveals his true motives, and banishes them through a time portal to the pre-apocalyptic past, intending to propagate war across timelines.

During a final battle against Loof, Jin, and their half-siblings, Mah King dominates initially but is impaled by Parome. His death midway through the series exposes him as a pawn of the Great Genma King. His legacy includes engineering the apocalypse through Genma infiltrators in human governments, who triggered nuclear holocaust to enable Genma dominion. Posthumously, his hybrid children—particularly Loof and Jin—become pivotal in opposing the Genma’s grand designs.
