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...
You are the one flower 
blooming in this rotten city.
أنت الزهرة التي تتفتّح في هذه المدينة الفاسدة
Du bist wie eine einzelne Blume,
die in diesem Drecksloch wächst.
Eres una flor que florece
en esta ciudad podrida.
Eres una flor que florece
en esta ciudad podrida.
Tu es la fleur qui pousse
dans ce quartier pourri.
Sei l'unico fiore che sboccia
 in questa città putrescente.
Você é a única flor nesta cidade podre.
Тебя можно назвать
одиноким цветком прогнившего города.
