Anime promotion video series for the smartphone game Project Tokyo Dolls.

A 25-minute cut of the film, referred to as Advent Children Special Edition, was screened at the 62nd Venice Film Festival in 2005. This version was later included as an extra on the two-disc special edition DVD.

In the world of Eos, the Niflheim Empire has conquered much of the land, leaving only the kingdom of Lucis, home to the last Crystal, to resist. The Crystal, located in Lucis' capital, Insomnia, holds immense power that the empire covets. To defend his realm, King Regis Lucis Caelum CXIII activated the Crystal’s magic to create a protective barrier around Insomnia. Additionally, he established the Kingsglaive, a specialized military force whose strength derives from the king himself. They stand guard against Niflheim and other dangers threatening Lucis. Nyx, a member of the Kingsglaive, earns the moniker "The Hero" among his comrades because of his overconfident nature and his eagerness to rescue others. His arrogance leads him to ignore orders from his superior, resulting in his demotion. As a consequence, Nyx now patrols the city gates. His life takes a new turn when rumors circulate that King Regis intends to negotiate a peace deal with the empire they've been fighting.

Two years have passed since the world was saved in a climactic battle, and the former members of the activist group Avalanche have each taken different paths. Tifa Lockhart now runs a new bar, while her longtime friend Cloud Strife has begun a courier service using his motorcycle. Although they have drifted apart from most of their old comrades, Cloud and Tifa maintain a fragile peace alongside the two children in their care—Marlene and Denzel. This tranquil existence begins to fracture when a mysterious illness and deep-seated grief cause Cloud to withdraw from his makeshift family. As he buries himself in work, Cloud is ambushed by three cloaked figures with silver hair who bear a startling resemblance to his arch-nemesis, Sephiroth. These foes relentlessly chase Cloud and injure those around him, forcing the former mercenary to face his personal demons even as he fights to defend his home and prevent Sephiroth's presence from returning to the planet.

Two years have passed since Sephiroth fell and Midgar was nearly destroyed. The survivors have rebuilt their lives in the newly constructed city of Edge. Cloud Strife and Tifa Lockhart operate a courier service while caring for Marlene, Barret’s adopted daughter, and an orphan named Denzel, all working toward a brighter future. But a mysterious illness called Geostigma begins to plague Cloud, Denzel, and other children in the city. Meanwhile, a group of powerful men start kidnapping children afflicted with Geostigma. Cloud sets out to rescue them, unaware that these kidnappers are connected to his old enemy Sephiroth. This forces Cloud to confront his past and battle his inner demons. With help from the friends who once saved the world, Cloud must unite with them again to overcome these new threats and protect the children of Edge.
