In a world governed by absolute hierarchy and rigid traditions, the mysterious "Order" maintains peace through an elite cadre of legendary servants known as the Maids. These are not mere housekeepers but highly skilled operatives trained in both etiquette and lethal combat, sworn to protect their charges at any cost.
The story follows a young, unassuming recruit who finds herself thrust into this high-stakes life of service and shadows. As she navigates the complex social machinations of the aristocracy and uncovers the dark, pulsating secrets hidden behind the pristine facades of grand estates, she must learn that in this world, every cup of tea served could be a tactical maneuver, and every bow hides a blade. Balancing domestic perfection with the dangerous duty of an enforcer, she soon realizes that the Order demands more than just loyalty—it demands the total erasure of the self.
