The world changed like a game. A survival VR game where zombies and monsters attack people. I was the last user of that game. An ordinary man running a restaurant. But his true identity is… a legendary “veteran player” who spent thousands of hours in a zombie survival VR game! One day, the virtual world he died and revived in countless times became reality. The zombie apocalypse begins suddenly. He awakens a dimensional gate ability simultaneously with the catastrophe, and begins moving between reality and another world to prepare for the coming end. And one by one, his past comrades reveal themselves—”Rabbit Lord” who revives infinitely, “Duck Butt Quack Quack” who controls monsters, and other powerful players beyond common sense begin to “log in” to the real world. The world collapses, and the boundary between humanity and survival instinct blurs. But he declares firmly: “This isn’t a game. But for me, it’s a familiar battlefield.” What final choice will the strongest former players face at the end—?
