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...
Not only are you looking after her, 
she's also eating our manjuu.
لست أنت من تعتني بها فحسب، بل إنّها
تأكل المانجو خاصّتنا أيضاً
Sie behandeln Pawoo
und bringen ihr unsere Manjū,
La cuidas tú y come mis manju.
La cuidas tú y come mis manju.
Entre vos soins et ma cuisine,
aucune maladie peut nous résister !
Non solo ti prendi cura di lei, 
ma mangia anche i nostri manjuu.
Além de ela comer o meu manjuu, 
você tá cuidando dela.
Мало того, что её вы лечите,
так она ещё и мои булки ест!
