Japan has become a wasteland devastated by the Rusty Wind which causes all things to rust away. A suspicious looking priest visits a checkpoint all alone, yet on his back rests a bow priests wouldn't use.
Meanwhile, Milo, a doctor running a clinic in the town of Imihama, is researching new medicines in secret in order to save his older sister, Pawoo, who's being corroded by the Rust. But that day a stranger appears before him...
A single draw of his bow,
،سحبة واحدة لقوسه
Wenn er seine Pfeile fliegen lässt,
Dispara una flecha
Dispara una flecha
Avec une seule de ses flèches,
Gli basta un singolo colpo
Uma só puxada no arco dele
Стоит ему выпустить стрелу...
