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.
