Good Hunting starts out in early 20th century China, on the cusp of colonized modernization. The son of a spirit hunter, Liang, manages to befriend a shape-shifting fox spirit named Yan and they meet over the years as steampunk technology develops and advances. When Liang’s father passes away, Liang moves to Hong Kong and becomes a skilled engineer. He encounters Yan again, only she has lost the ability to shapeshift, due to the magic of the land being disrupted by the progress of machines. After Yan is maimed and transformed into a cyborg against her own will, Liang helps to replace and upgrade Yan’s mechanical body that allows her once again to transform into a fox, albeit a cybernetic one, and she sets out into the city to hunt once more.
