   Summary

   In the year 40XX humans and monsters have successfully established colonies in planets far away from our own, in other galaxies. Polaris VI is one of the many missions to deliver supplies to a space station overseeing one such colony. With Cross as the commander, Killer as the pilot, Dust as the medical staff onboard, and Horror as the engineer, this mission should be successful and be back on earth ten years after departure, as scheduled… little do they know this mission will change their lives forever.
