Shirogane no Torikago takes place in the city of Roddo Town. Two hundred years ago, a great war lead to the near destruction of mankind. The few people that did remain following the war started off with a clean slate, built new towns and connected the towns via steam-powered train. Soon, airplanes were invented and mankind took to the skies.

Mysterious children started to be born in this new world, children with strange powers. So strange and feared were these powers that adults sent all the special children to Roddo Town, which is itself separated from the other towns of the world and is surrounded by a great steel wall.

The game's main character is Woll, one such special child. Woll and the other kids of Roddo Town have the ability to read the memories of objects and know their pasts. One day, Woll uses his powers to fix the train station manager's television, and he's summoned to the Roddo Town mayor's place. He expects that he will be punished for having used his powers.

Instead, the mayor asks him to fix a plane from 200 years ago and make it so that it can fly again. A great floating fortress called Sky Ray was built 200 years ago and is believed to contain the secrets into long lost pre-war technology. Woll, along with Andy, Bibi, Katie, Mini and the other boys and girls of the town start off on an adventure that will change not just their own lives, but the lives of people throughout the world.
