Final Fantasy VII: Advent Children

Two years after the final battle with Sephiroth, Midgar lies in ruins, haunted by a mysterious illness known as Geostigma that brings death to those afflicted, leaving its people struggling for a cure. Cloud Strife, still suffering from the disease himself, sets out to rescue children kidnapped by Kadaj, Loz, and Yazoo - physical manifestations of Sephiroth's spirit seeking to resurrect him using Jenova's remains. In the midst of action-packed battles against monstrous creatures and treacherous foes, Cloud must confront his own emotional scars and ultimately face Sephiroth in a climactic duel that will determine the fate of the Planet.
