Fullmetal Alchemist (manga)

"Fullmetal Alchemist: Brotherhood"

"There is a saying that if you desire something, you should give up something of equivalent value for it. This can be said to be "Equivalent Trade" in my work. In any of the books talking about alchemy, this saying will appear. I thought this was how life should be like. The theme material was a moment of inspiration kind of thing."
