Elves are smart, long-lived, and attuned to the wind. Wips can manipulate flame. Segitts have incredible muscular strength. Somehow, humans have learned to survive. In the racially-diverse technopolis of the Seventh Republic, they even dominate. Out of all the strange and terrible corners of the world, at least humans can feel safe in this one. Here, there’s strength in numbers. Within this country's peacekeeping police force lies a special 13th Division reserved for the troublemakers, eccentrics, and other such unorthodox individuals of the organization. One human, though? Pitifully outclassed against a single member of almost any other race; it’d never be a fair fight—unless that human was a Keeper or carrying some serious Class A police tech. But tech can be stolen, and far from all Keepers are on the side of justice. Strict border checks. Pervasive, draconian surveillance, with camera eyes and a computerized spine running signals to the heart of the NPA, the National Police Agency. And the physical hands of this digital dragon? The police themselves. Sometimes the hands of justice grip too tight. So how’s a nation supposed to keep the peace? Among this police force, one division dares to stand against the current. One division dares to disobey orders, break regulations, refuse to work overtime, and generally make themselves useless to everyone, especially their bosses, except for people in need. That is our protagonist Hiryuu Ruka. Despite his outstanding capabilities as an officer, his problematic demeanor and obsession with the events that sparked a past tragedy invited the ire of the upper management and landed him where he is now: the 13th Division of the NPA. The Sideliners. Ruka prefers to work alone, but the addition of an Elf by the name of Claris to the division put an end to his lone-wolf work style as he was made to pair up with the fresh-out-of-police-school newcomer. As Ruka spends his days bickering with the incompetent newcomer and his incompetent superiors, he rescues a girl who's come to the Seventh Republic in seek of refuge, setting in motion events that would change his life forever.
