I'm a librarian who loves anime, manga, and reading a wide variety of genres.
"And yes, some of the fields near the mine went bad from the dust, but everyone's lives improved. Some people might regret losing our green fields and orchards, but most of us were happy enough with the wealth we got in return.

For the love of gold."
