Final Fantasy VII: Advent Children

2 years have passed since the last fight with Sephiroth. Though Midgar, city of mako, city of wealth, has already been reduced to ruins, its people slowly but steadily walk the path to reconstruction. However, a mysterious disease named Geostigma torments them. Without a cure in sight, it brings death to the afflicted, one after another, robbing individuals in the fledgling hope.
