Amon: The Apocalypse of Devilman , directed by Umanosuke Iida (who worked on The Birth ) and written by Go Nagai himself alongside Akinori Endo, picks up immediately where the first OVA left off. The animation studio was Oh! Production, with character design and animation direction by the legendary Yoshihiko Umakoshi (later known for Casshern Sins and My Hero Academia ). Umakoshi’s work here is raw, muscular, and grotesquely beautiful—a perfect marriage of Nagai’s crude, expressive style and high-fidelity anime detail.
The demon Amon —the original, unbroken personality of the demon Akira hosts—begins to reawaken. Akira’s body mutates, not into the controlled Devilman, but into the hulking, bestial form of the ancient warrior Amon. His eyes lose all human recognition. His friends, Miki and Miko, look on in horror as the monster that once served Akira becomes the master. amon - the apocalypse of devilman
The voice cast features the iconic Ichirō Nagai as the narrator (his deep, ominous tone setting the stage), with Tomohiro Nishimura as a tormented Akira Fudo, and Kaneto Shiozawa as the cold, charismatic Ryo Asuka. The OVA opens not with Akira, but with a stunning, wordless prologue: the story of the original Devilman. Millennia ago, a human warrior named Amon was the most powerful demon in hell, serving the demon lord Zennon. Amon refused to bow to the rising power of Satan, leading a rebellion. For his defiance, Amon was torn apart by the demon general Kaim and his consciousness was sealed within a human sacrifice—setting the stage for the modern era.

The second half of the OVA is less a narrative and more a descent into a shared nightmare. Amon rampages, killing demons and humans alike. Ryo watches with a mixture of fascination and cold calculation. The climax is not a heroic battle but a brutal, primal clash between Amon and the demon general Kaim—the very demon who originally dismembered him. Their fight is a cataclysmic orgy of blood, severed limbs, and earth-shattering force, rendered with sickening detail. Umakoshi’s work here is raw, muscular, and grotesquely
The title is The Apocalypse of Devilman , not of the World . While demons are attacking Earth, the true apocalypse here is the death of Akira Fudo’s soul. The external chaos mirrors the internal disintegration. It’s a deeply personal, psychological apocalypse, making it far more devastating than any giant monster attack. Animation and Direction: A Masterclass in Body Horror Amon is not a film for the squeamish. The violence is constant, graphic, and deeply tactile. Limbs are torn off with sinew audibly snapping. Blood sprays in impossible geysers. Demons are designed with a horrifying biological realism—they look like cancerous, chitinous fusions of human and insectoid features.
