AC-197. Peace has returned to the people. And from this point on in history, weapons known as mobile suits, including the Gundams, were never seen again in the Earth Sphere. However, as long as mankind exists, there will always be battles. And that is precisely why an organization called the Preventers must exist. Heero and the others of PREVENTER-7 embark on a new operation to extinguish the flames that threaten to consume the perfect peace. (Source: Kadokawa, translated)
