Two years after the events in "Final Fantasy VII", a disease called 'Seikon-Shoukougun', or 'Geostigma', is spreading through the planet. This disease is believed to have been caused by the body fighting off foreign material that invaded the body two years earlier, at the end of "Final Fantasy VII". Guilt-ridden and haunted by his past, ex-SOLDIER Cloud Strife has decided to live a secluded, solitary life away from his friends while maintaining "Strife's Delivery Service", whose headquarters is located in Tifa Lockheart's bar, the Seventh Heaven. Tifa's bar serves as an orphanage for children stricken with Geostigma. Here, Tifa keeps an eye on Barret's six-year-old daughter, Marlene, while Barret searches the planet for an alternative energy source to the Planet's energy, Mako. One day, Cloud receives a phone call from the former Shinra, Inc. president, Rufus, asking him for protection from a mysterious man named Kadaj. Kadaj, in the meantime, along with his brothers Loz and Yazoo, are searching for their "mother", and seem to believe that Cloud knows where to find her. Meanwhile, Vincent Valentine has been wandering the planet gathering information on Kadaj's scheme, and Cloud and his friends must come together again to fight these new enemies. Written by Andrea

Two years after "Final Fantasy 7", life seems to have returned to a state of normality after Sephiroth's attempts at mass genocide and the danger of Meteor. On the edge of the ruins of the metropolis Midgar, a new city has thrived, called the Edge and at it's center lies a monument that entails no one will forget Meteor and the ones who died. Cloud Strife, the hero who defeated Sephiroth, is a delivery boy now, no longer interested in fighting wars or leading rebellions. The world is at peace, and AVALANCHE is gone it's separate ways. Tifa Lockheart has reopened the new 7th Heaven, in the Edge, looking after Marlene and other orphans, including Denzel. Barret Wallace is working with the WRO in finding new energy sources to supply the world now that Mako is no longer used. Cid Highwind is also working with the WRO, as an airship pilot and leader of their air fleet. Reeve (and Cait Sith) is now heading the WRO and working, striving, to create a better world for all. Vincent Valentine has returned to solace, switching his places between his mansion home in Nibleheim and the Sleeping Forest, and the Forgotten City. Yuffie Kirisagi is back in Wutai, though what the Ninja is doing is unknown to all. But despite this lull in adventure, there is something that is striving the world. Geostigma, the Sephiroth, JENOVA's memetic legacy. A disease that counters the body's own defence system in on itself and causes it to destroy itself. Rufus ShinRa, ex-President of Midgar, is a sufferer of the disease, along with the ex-SOLDIER Cloud, and lives now in his hide-away home the Healin Lodge with his faithful bodyguards, the Turks. But who are the mysterious silver haired band, known as Kadaj's Gang? Kadaj, Loz and Yazoo, all of silver hair and teal eyes. Who are these strange people, who appear so much like Sephiroth?
