Mugen is a ferocious, animalistic warrior with a fighting style inspired by break-dancing. Jin is a ronin samurai who wanders the countryside alone. They may not be friends, but their paths continually cross. And when ditzy waitress Fuu gets them out of hot water with the local magistrate, they agree to join her search for the “samurai who smells of sunflowers.”

After a successful robbery leaves famed thief Lupin III and his partner Jigen with nothing but a large amount of fake money, the so called “Goat Bills”, he decides to track down the counterfeiter responsible – and steal any other treasures he may find in the Castle of Cagliostro, including the ‘damsel in distress’ he finds imprisoned there.
