In the racially diverse technopolis of the Seventh Republic, humans manage to hold their own through sheer numbers, pervasive surveillance, and the NPA police force. Most human officers enforce the law. One division does not follow orders, breaks regulations, and makes itself as unhelpful to management as possible — while being the only unit ordinary people in trouble can count on. The 13th Division. The Sideliners. A noir mystery visual novel set in a fantasy city where humans are outclassed by almost every other race.
