Ichise is currently living his life as a fighter in an underground fighting ring. He is incredibly strong and is rewarded for his efforts with a nice whore. She goes kind of crazy and he throws her off during their 'love making'. As a result, her 'employer', Aida, calls up a member of Organ, Isshii, to punish Ichise. Isshii cuts off Ichise's right arm.

At the same time, we see our first sighting of Yoshii, a member of the Class who has come down to Lux for reasons unknown at this point. When he gets to the bottom of the stairs that connect the two worlds, he meets Ran, a girl from the nearby village of Gabe, which is situated on the outskits of Lux. Ran leads him to the Elder of Gabe where they are soon accosted by a couple members of the Alliance. Yoshii protects Ran and the Elder and fights them off.

We are also introduced to Oonishi, the leader of Organ.

Ran is overwhelmed by a vision of Ichise's future.

Gabe acquires high-quality weapons, beyond even those that the Alliance or Lakan could own and are preparing for a revolution.

Ran is being discussed as a Watcher, relieving the duties her grandfather. The invasion of Shapes has reached the city of Lakan. A group of Salvation Alliance members discover someone is Texhnolyzed.

Ran has a vision of the Obelisk sweeping over her. The killings, mostly against the Organo continue. Shinji and Onishi meet with the elders of Class.

Voices are creeping the underground world (the film which Doc and Ichise watched) retelling Lux's history, the surface world of Hades, and many prophetic things about Ichise. Shinji attemps to kill everyone of the Class. A voice sounding like Ran tells Onishi to kill the Obelisk.

Ichise and Kano have a showdown. What will become or remain of the city of Lux? More origins of the Lux is revealed.
