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.
In fact, director Masaaki Yuasa’s Devilman Crybaby pays clear homage to Amon , particularly in its final episodes where Akira loses control and the world descends into a similar red-hazed, limb-strewn chaos. However, Yuasa’s version retains a sliver of melancholic humanity, while Amon remains resolutely, terrifyingly empty. Amon: The Apocalypse of Devilman is not an easy watch. It is a film that hates its protagonist, despises the idea of a happy ending, and wallows in the grotesque. But that is precisely its power. It is the most faithful adaptation of Go Nagai’s core thesis: that humanity is fragile, that the monster within is always waiting, and that in the war between angels and demons, humans are nothing but casualties. amon - the apocalypse of devilman
For fans of psychological horror, body horror, and animation that pushes boundaries, Amon is essential viewing. It is a masterpiece of despair—a howling, bloody scream into the void, reminding us that sometimes, the hero doesn’t just lose. He becomes the apocalypse.

Ryo Asuka is a tragic figure in the manga, but in Amon , his callousness is on full display. He treats Akira’s disintegration as a scientific data point. He created Devilman, and now he watches his creation self-destruct. The OVA hints at Ryo’s true nature (Satan) but doesn’t fully reveal it, making him seem less like a fallen angel and more like a detached, monstrous god playing with pawns. Umakoshi’s work here is raw, muscular, and grotesquely
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.
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.
