Metallic Rouge - S01

After humanity defeated an alien race called the Usurpers with the help of combat androids known as Neans, they colonized Mars and settled into an era of peace. No longer needed as soldiers, the Neans became laborers, treated as second-class citizens under human control. They rely on their human masters for daily doses of Nectar-a drug essential to their survival. Among the Neans exist rare, independent units called Proto-Neans, capable of summoning powerful metallic exoskeletons with abilities beyond human limits. Rouge Redstar, one such Proto-Nean, works secretly for Aletheia-the government agency that regulates Neans-alongside her human partner, Naomi Orthmann. Their mission is to hunt down the Immortal Nine, a group of rogue Proto-Neans with unknown motives against humanity. Meanwhile, an investigator arrives on Mars to pursue a string of murders, with Rouge as the main suspect. As Rouge and Naomi get closer to uncovering the truth about the Immortal Nine, they also begin unraveling startling secrets about their own organization.
