Sex & Fury chronicles Ocho's exploits as she searches for her father's killers, each identified by unique tattoos on their backs (a deer, a boar, and a butterfly). Along the way, she also crosses paths with Shunosuke, a radical set on murdering prominent politician Kurokawa, and Christina, an American spy posing as a gambler.

The Kanto Gypsies, a tough girl gang, hide out from the law in the middle of a disputed gang territory, where they end up getting kidnapped by sinister underworld thugs. After breaking free, the girls set their sights on one thing: revenge. Miki Sugimoto stars as girl boss Komasa, the ruthless and sadistic leader of the Kanto Gypsies who possesses more than enough brains to match her killer looks.
