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...
That client I had the other 
day was just the worst!
!ذلك الزبون الّذي جاءني قبل أيّام كان الأسوأ
Dieser eine Kunde neulich
war echt das Letzte!
Le client de la dernière fois,
c’était une plaie !
Il cliente dell'altro giorno è stato pessimo!
O cliente que atendi outro dia foi o pior!
Тут на днях заходил один, хуже некуда!
