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 pilgrimaging monks 
probably don't know this,
،أنتم الرّهبان الحجّاج لا تعلمون هذا غالباً
Mönche auf Pilgerreise
wissen das vermutlich nicht,
Supongo que los monjes no lo saben,
Supongo que los monjes no lo sabéis,
Tu dois sûrement pas savoir,
Voi monaci pellegrini 
probabilmente non lo sapete,
Talvez vocês, monges 
peregrinadores, não saibam,
Монахи навроде тебя вряд ли в курсе,
