"The last trump card."
The National Strategic Defense Force is an organization that protects the nation and its citizens through a wide range of activities, including responding to enemy attacks, national terrorism, and disaster rescue.
This force is divided into numerous units.
Among them, the 7th Division is hailed as Heroes by the public. They are the elite of the NSDF, a top-tier unit that handles the bulk of active missions.
However, there is a unit that transcends even the 7th Division: the 0th Division. They are the nation's ultimate military power, consisting of only three members. Among them, Guest is the most threatening and powerful. Generally, they do not accept standard missions; they are deployed only during crises of national extinction, large-scale disasters, or when defeat is imminent. Within the military and the public, they are regarded as a mere urban legend that no one truly believes in. Yet their actual strength is overwhelming, leading the national high command to refer to them as the Final Trump Card.
