Due to a massive earthquake, an underground portion of Tokyo has been separated from the outside world. Because of the limited supply of food and the constant threat of inter-group warfare, the underground city's survivors have dubbed the area Hell City. When the story begins, Evil Town has been in existence for several months.
This time, there is a peaceful post-apocalyptic town known as Hope Town. The biker gang Hell's Wind show up and ransack it. Violence Jack makes his entrance here. The episode starts as a young woman, Jun, and her boyfriend, Tetsuya, are attacked. Tetsuya is murdered by Hell's Wind, and they assault and rape the terrified Jun soon after.
A great comet hurls from space and collides with Earth, causing a cataclysmic earthquake that rocks the Kanto Plain of Japan, killing several and reducing the cites to rubble. In this time of weakness, a ruthless man known as the Slum King took control of the Kanto Plain with his brute force and rules it with an iron fist. However, in the middle of a trek across the land with his great forces at his side, he encounters a mighty beast-like man wearing a battered green jacket and a yellow ascot who slaughters his men and then targets the Slum King himself. They clash, but their fight is interrupted by a sudden massive tsunami that separates the two.
