In the mountainous Asian country of Uddiyana a civil war rages. No end lay in sight for the war-torn nation until a lone photographer snapped an iconic image that would come to be known simply as "Flag." Hope arises as the many factions involved begin an approach to peace, rousing the call for a ceasefire behind the featured flag.
When an unknown guerilla sect steals this symbol of unity, a U.N. Special Development Command unit is dispatched using the latest in military technology, a transforming bipedal exoskeleton known as the HAVWC system. Recruited to document this mission is a war-time journalist, the author of the "Flag" photograph, Saeko Shirasu.
Witness the trials and triumphs of a peacekeeping taskforce behind the camera's view-finder as they take their first steps towards the recovery of the road to peace and discover the truth behind a struggle.
