In the 37th year of the Eternal Burning Century, the thick fog in Gear City never cleared. It was like a rag with hair, covering up the life of this big city made of steel.
The Black Iron Orphanage is located in the darkest place in the city, as if it is in the belly of this steel giant. The rusty barbed wire fence is like a dividing line, clearly distinguishing this place from the outside world. Here are the people who are barely alive, and over there are those who look hopeful, but are actually false hopes.
