Gameoverse X Human Male Reader

In the Gameoverse, defeating a game's villain causes that entire world to collapse and disappear forever. After surviving the destruction of her own universe, Kit travels across countless game worlds, secretly helping villains defeat their heroes in hopes of preventing more annihilation. During her journey, Kit meets Y/N L/N, the former leader of the Starboys, a once-legendary galactic team wiped out during a catastrophic multiversal war. Haunted by the loss of his teammates, uncle, and his former girlfriend, Lucy, Y/N wanders the collapsing worlds in advanced star-tech armor, struggling to move on from his past. As he fights alongside Kit, the two slowly grow closer, though Y/N remains uncertain about opening his heart again after everything he lost.
