Set seven years prior to the events of the first Final Fantasy VII, the Shinra Company is rapidly increasing its influence through its monopoly on mako energy and military might. With the burgeoning city of Midgar as its base and symbol of prosperity, Shinra is on the verge of establishing absolute dominance over the world. SOLDIER is a group of skilled combat operatives within Shinra. The elite within the group — those strong enough to be deemed SOLDIER 1st Class — are respected and idolized by the citizenry. Zack is a young SOLDIER 2nd Class who aspires to become a 1st. He spends his days carrying out assignments under the guidance of his 1st Class mentor, Angeal.

The ones assigned to the mission are Zack, Angeal, and the 1st Class hero who is known the world over as Sephiroth... What truths lie behind Genesis's disappearance? What secrets bind the three SOLDIER 1st Class operatives? For Zack, a cruel and fateful struggle awaits...
