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...
One might even call this Gunma 
Prefecture's last line of defense.
قد يعتبر المرء بأنّ هذا هو خطّ الدفاع
الأخير لمحافظة غونما
Wir sind quasi Gunmas
letzte Verteidigungslinie!
Esta es la última línea
de defensa de Gunma.
Esta es la última línea
de defensa de Gunma.
On est la dernière ligne de défense
de la préfecture.
Si potrebbe persino definire l'ultima linea 
di difesa della prefettura di Gunma.
Até falam que Gunma é 
a última linha defesa.
Можно сказать, у нас тут
последняя линия обороны Гуммы!
