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...
Listen. Don't get caught, you hear?
اسمع. لا تُصَب بالعدوى، حسناً؟
Lass dich auf keinen Fall erwischen.
Que no te descubran.
Que no te pillen.
Te fais surtout pas choper.
Ascolta, non devi farti catturare.
Ouçam bem. Não sejam pegos, viu?
Запомни, ни за что не попадись страже.
