Levih Rah, once a martial arts disciple of Agni Lai, honed his skills alongside rival Genichirou Izayoi. Consumed by envy at Genichirou’s prowess, he surrendered to demonic possession, abandoning his humanity to seize power. This pact amplified his abilities, enabling him to overpower Genichirou in a duel that unleashed the Devil Shake—a cataclysmic earthquake reducing Tokyo’s Shinjuku to a demonic ruin.

A decade later, Levih Rah plotted to merge the human and demon realms by targeting the World President. His scheme centered on sacrificing the leader’s daughter, Sayaka Rama, to finalize the ritual, simultaneously advancing his dominion and diverting Agni Lai, the president’s protector.

His powers encompassed shape-shifting, conjuring demons, and weaving illusions, with a body dissolving into bat swarms. Three guardian demons enforced his will, eliminating opposition. Though nearly invincible, his arrogance blinded him to the resolve of Genichirou’s son, Kyoya Izayoi, who wielded the sacred Ashura blade. Empowered by ancestral legacy and allies, Kyoya shattered Levih Rah’s form, disrupting the ritual and exiling the demons.

Levih Rah’s ambition sought to transcend mortal confines through the worlds’ fusion, sacrificing allies and innocents without remorse. His downfall epitomized corruption by hubris, contrasting the narrative’s redemption themes.

Expanded lore, including role-playing adaptations, frames him as a sorcerer skilled in ceremonial magic, his actions a fragment of humanity’s eternal clash against supernatural threats. His defeat left the demonic realm’s menace simmering, hinting at potential resurgence through lingering influence or legacy.
