In 20xx, a civil war erupted in a small Asian country despite the deployment of UN forces. However, an accidental photograph taken on the battlefield accelerated the peace process: an image of a flag that came to symbolize peace. Yet, just as the peace agreement was about to be finalized, an armed extremist group stole the flag to sabotage the truce. To recover the flag, the UN dispatched the Special Development Command (SDC), equipped with the High Agility Versatile Weapon Carrier (HAVWC), accompanied by an embedded photojournalist to document their operations. That photojournalist is Saeko Shirasu—the young camerawoman who originally captured the image of the flag.
