The repeated conflicts between humans and Reploids have left the Earth in ruins. Unable to cope with the planet's devastation, humanity finally looks toward space for survival. The human residential satellite 'Moon' is developed, and with the completion of the orbital elevator 'Jakob,' numerous New Generation Reploids are transported to build the base. Like Axl, these New Generation Reploids possess transformation abilities based on DNA data, a power that initially seemed to contribute greatly to the world. However, X is horrified by what he sees at the site of a Jakob accident: they have absorbed the DNA of Sigma, who possesses a resilient body. As if responding to the accident at Jakob, Reploid rebellions break out in various locations. To handle this, X heads into space with his comrades. What fate awaits them in the vastness of space?
