The underground city of Lukuss is ruled by gangs and religious fanatics who have all carved their own piece out of the city. Peace is held together by a very fragile balance. But now the city appears to be on the verge of chaos as that balance begins to fall apart. Four individual lives hold the city's fate in their hands: Onishi: the leader of the most powerful Gang in Lukuss, Yoshii a mysterious man from the surface world, Ran: A young girl who can see into the future and Ichise: a loner who has had his arm and leg replaced with the incredible science known as Texhnolyze. One of these four will try to destroy Lukuss while the others will either try to save the city or themselves from a terrible fate. But who will win?
