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...
Well, we're really grateful to both 
you and your sister, Pawoo-san.
حسناً، نحن ممتنّون لك ولأختك باوو-سان
Wir sind dir und Pawoo
wirklich dankbar.
Les estoy agradecida. A ti y a Pawoo.
Os estoy agradecida. A ti y a Pawoo.
Nous sommes très reconnaissants
envers vous et Pawoo.
Beh, siamo veramente grati 
a lei e a sua sorella, Pawoo.
Somos muito gratas a você e à Pawoo-san.
Мы все здесь очень благодарны
и тебе, и Пау.
