Murder Drone x Male!Oc)
Ever since the Murder Drones descended upon Copper-9, Yuri Morozov has done everything he could to keep his little sister, Doll, and his younger cousin, Uzi, safe. Forced to grow up long before he should have, he spends his days maintaining the bunker's aging systems, scavenging for supplies, and studying whatever remnants remain of the fallen human colony.
But after stumbling upon a hidden storage closet containing his late Aunt Nori's bizarre journals, diagrams, and conspiracy notes about the Murder Drones-and something called the Absolute Solver-Yuri realizes the predators roaming the frozen wasteland are only part of a much larger nightmare.
As long-buried secrets begin to surface, Yuri must uncover the truth behind Copper-9's destruction before the force lurking beneath the ice awakens once more.
