en CB01 OFFICIAL. Year 2086. Kate Sorin never imagined how volunteering herself as "base citizen" for Project Shell would determine her fate. The UNCORP claimed that the creation of the cyber-clones would be the bridge to a free and equal society, without thinking that their human nature would fight against the role they were created for: to be slaves. Soon began the riots. The clones started a rebellion, trying to escape using any means. To control outbreaks of violence and retrieve escaped units the UNCORP created a specialized police unit, the CHD (Clone Hunter Division). The individual 0258 escaped impersonating Kate, but everything went wrong and she saw herself forced to kidnap Kate´s daughter to survive, who died in the crossfire. Since that moment, Kate joined the CHD with a single goal, to find 0258 and avenge the death of his daughter.
