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...
And the Rust has almost 
reached your heart!
!وكاد الصدأ يصل قلبكِ
Der Rost hat fast
dein Herz erreicht!
¡El óxido está cerca de tu corazón!
¡El óxido está cerca de tu corazón!
La rouillure a presque atteint ton cœur !
Ta vie passe avant le travail !
E la Ruggine ha quasi raggiunto il tuo cuore!
A Ferrugem está prestes a chegar no coração!
Твоё сердце ведь скоро заржавеет!
Тебе работа важнее жизни?!
