Violet Song Jat Shariff, a woman infected with hemoglophagia (a fictional vampire-like disease), lives in a future dystopia where anyone infected with the contagious disease is immediately sentenced to death. With her advanced martial arts skills, a group of rebel hemophages, and a boy named Six, whose blood may contain a cure for the disease, Violet goes on a mission to overthrow the futuristic government and defeat Ferdinand Daxus.

A novelization of the film was written by Yvonne Navarro, with more back-story and character development. The book differs from the film in a number of ways, including a more ambiguous ending and the removal of some of the plot twists. An anime series titled Ultraviolet: Code 044 was released by the Japanese anime satellite television network Animax, and created by Madhouse.
