Only one episode of this was partially completed, the released version containing numerous examples of animation that is missing in-between frames. The story as such concerned the arrival of the real Chojin as he/she (a hermaphrodite) makes moves to wipe out all life on Earth. Interestingly, the setup for the show was far more heavily connected with the first two, more popular, chapters in the Urotsukidoji saga, with appearances by Nagumo and Akemi (unseen since the early episodes of Part III), and redesigned character models that more closely resembled the earlier episodes. Some of the less popular characters introduced in chapters III and IV, particularly Buju, were nowhere to be seen. Nevertheless, such strategies did little to get this final saga off the ground and the story was shelved.

It is the age of the Overfiend, and flesh-hungry monsters rule the Earth. Immortal half-demon Amano Jyaku travels the wasteland, witness to the rape and torture of the human race.

As the Overfiend slumbers, the mad emperor Caesar rises to power, enslaving a new race of demon beasts. Into this cruel existence is born the Lord of Chaos, the Overfiend's nemesis. As the blood-thirsty beasts capture the tyrant's daughter in a brutal coup, the Overfiend must awaken to an apocalyptic battle of the Gods.

In this controversial and graphic anime film, a teenage boy becomes possessed by a demonic entity and embarks on a rampage of violence and sexual violence. As the demon's power grows, the boy's cruel and sadistic behavior escalates, leaving a trail of blood and death in his wake.
