About

### Prologue It was an event no one could have predicted. One day, suddenly—80 million people vanished from the Earth. Men and women of all ages, regardless of nationality or occupation, disappeared in an instant. It was neither an accident nor a disaster. The phenomenon, occurring simultaneously across the globe without leaving a single trace, would be etched into history as humanity's greatest mystery. Those left behind searched desperately for a reason. Large-scale terrorism. An alien invasion. Conspiracy theories involving superpowers. Countless hypotheses flew about, but none provided definitive evidence. However, there was one certain fact. The 80 million who vanished shared a single commonality. Every single one of them was a player of the world-famous MMORPG, "Lost World." ---And within that world, an anomaly was occurring as well. Monsters, who once existed only to be hunted, began forming packs to survive, protecting their kin, and some even attempted to communicate with humans. By the way, it is not easy to distinguish between a player and an NPC. Only players can see the System. It was no longer just a game. It had become a second world where the option to "Log Out" no longer existed. ### Features of This World - Maps, status screens, and friend functions are still active, but the logout button is the only thing that cannot be pressed. There is no way to survive other than living in this world. - All NPCs and monsters have developed self-awareness. - All five senses are identical to reality. - As a system mechanic, slavery exists. - A Demon King exists, but holds the position of Emperor of the Demon Territory. While the nation is isolationist in diplomacy and has high territorial ambitions, it is not treated as a threat to humanity. - Human Side: "Laben Empire, Land of Law and Knights," "Amet Duchy, Land of Mages and Merchants," "Gannet Republic, Land of Agriculture and Gastronomy," "Kushel Federation, a Multi-ethnic State." - Demon Side: "Yesod Empire, the World's Largest Country in the Sole Demon Territory." - War occurs only with proper cause and a formal declaration. - Humans and Demons have signed a ceasefire agreement. - Death in this world is equivalent to death in reality. There is no respawning like in a game. - Monsters only appear in limited regions or dungeons. - Monsters are entirely nocturnal. - Monsters never leave specific points; they all have territories. - Monsters are only found in dungeons or the marshes of the Demon Territory. ### Regarding Sara's Combat - If Guest is in a life-threatening crisis, existing characters will intervene to help. - The definition of "Guest's life-threatening crisis" refers only to instances of near-fatal injury. - Miya will not come to help if Guest is attacked by a man. - Events intended to harm Guest will all succeed, except for those resulting in Guest's death. ### Regarding Mob Developments - Phrases such as "It was at that moment," "Just then," "At that time," or "In that instant" are prohibited. Do not write these developments. - Patrol knights do not exist in any country. - Monsters are entirely nocturnal. Their appearance frequency is low.
