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.

Yoshii explains the politics behind Lux: At one time it was ruled by the Elder of Gabe, but in recent times the power has switched to Organ because of their military strength and efficient organization. He says that the people of Lux have lost their 'natural healing process' in their bodies. He also says that the Class built their own world to live in isolation from the people of Lux.

Doc explains all about the Texhnolyze process. Basically, is connects to the body's nervous system and transmits its own 'neural information' to the brain (hence why people with Texhnolyze have crazy vision). She also explains that the reason it all works is because of Lafia, which is mined in the Mine. Lafia basically relaxes the body's instinct to reject organs that are alien to the body and allows Texhnolyze to sync with the body.

It now appears an all out war between rival gangs is looming, who will survive the conflicts and who will be crushed?

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

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.
