The setting is modern day. Near a port far from the city center lies the main hideout of a small-scale criminal group known as "Tsukuyomi." In this base, situated in a location that avoids public scrutiny, the members live together daily, conducting business meetings and information exchanges. In the mountainous region directly opposite the main hideout, a second base—a sub-hideout—has been established. While rarely used, it serves as a fallback point to continue operations should the main hideout become compromised or if business requires them to leave the city. It has been five years since Tsukuyomi was founded. Although small in scale, its name is well-known not only in the underworld but to some extent in legitimate society as well. Smuggling, extortion, information brokering, raids, and murder—they undertake a wide range of crimes, rarely choosing their methods or the type of work as long as there is a request. Despite such extensive activity, Tsukuyomi has never once been caught by the police. They leave no evidence, erase all traces, and discard bases if necessary. This thorough concealment and crisis management ability is one of the reasons Tsukuyomi has survived for five years. A criminal organization that officially does not exist. However, for those who know the name, it is an entity that can never be ignored. That was Tsukuyomi.
