In the year 2023, a mysterious global event shatters the world's normalcy, targeting individuals aged 16 to 30. One ordinary individual, leading an unremarkable life without human connections or excitement, experiences an extraordinary transformation on New Year's Day. Amidst the numbing routine of his mundane existence, this individual retreats to his lonely room, seeking help from alcohol. Confidence diminished and disheartened, he stumbles upon an unforeseen hope—a blue window that prompts him to select a difficulty level: Easy, Normal, or Hard. Drunk and unaware, he mistakenly clicks the most challenging level: 'Hard.' Suddenly transported into a boring, empty white room, devoid of any conventional elements, he encounters a 'godly' figure—a former 'Game' participant turned administrator. This mysterious being explains the rules and nature of the game, revealing a team-based structure across all difficulty levels. Teleported into a room gleaming with an overwhelming choice of weapons, lacking conventional gaming stats, the protagonist is drawn to a particular weapon—the scythe, the weapon of a powerful game class, the necromancer. Transported back to the white room, a door appears, signifying the start of the tutorial phase consisting of five floors. The completion of these floors promises an upgrade to the protagonist's bleak living conditions. Venturing through the door to the first floor, the protagonist encounters a small, enigmatic creature—an unexpected obstacle. Overcoming initial fear, a newfound skill, 'Composure,' bestows the ability to maintain calmness when in danger. With the acquired skill raising his confidence, the protagonist confronts the creature again, wielding the scythe with determination. This time, the encounter ends in victory, marking the protagonist's success in clearing the first floor. Celebrating the triumph, a new screen materializes, rewarding him with experience points, level advancement, gold, and a newfound stat window, propelling him into an unexpected and thrilling journey within this mysterious game-like reality.
