The Nanosuit Soldier (Goddess of Victory Nikke Harem x Male Reader)

In the year 2055, Earth was invaded by a mechanical alien race known as Raptures. These machines destroyed every city across the globe and forced most of humanity to live underground in a giant city called the Ark. About a quarter of humanity stayed on the surface and live in a dome that covers a fifth of the United States. The dome is controlled by CryNet Enforcement & Local Logistics, or better known as CELL, and the people who live there have to work for their right to stay there or be thrown out of the dome and be at the mercy of the Raptures.

Over a century later, Y/N L/N, a twenty-eight-year-old CELL Recon soldier, spends his days guarding the CELL dome from any rapture that gets close to the walls. Y/N hates his job and wishes that he would go to the Ark like his parents and sister did over ten years ago, but he was forced to stay and work with his older brother Trevor in order to pay off their family's debt to the CELL government. Everything was moving along at a leisure pace until one mission went south and Y/N and Trevor were left behind and Trevor was killed by the raptures.

Y/N managed to return to the CELL Dome, but he lost all faith in the CELL government, and he decided to leave the dome. While Y/N planned his escape, he found a file left behind by his deceased grandfather. Inside the file were reports of a weapon that was created by his ancestor. In the file was also the location of the base where the weapon is. A suit made of alien technology which could turn the tide in this war.

Y/N managed to escape the CELL Dome and was deemed a traitor to CELL which put a target for termination on his back. Y/N explored the surface while surviving any raptures that he encountered until he found the bunker that was in the file. Inside were dozens of weapons and hundreds of files from the year 2020 including a weird suit that was made from technology from a different alien race that predated the rapture invasion. A suit with the codename "Savior".
