The boy climbed out of the furnace where scrap iron was burned,
Carrying a cursed, talking iron spine,
In the giant steel city where steam and gears roar,
He must learn to coexist with this "rebellious bone",
Until I found my own bones,
It was during the God-Slaying War a hundred years ago that
The only weapon that can kill and revive the ancient god.
Purpose: "Carrying the bones of killing gods on your back to save people; living in the steel hell, witness your true intentions."
