Master thief Lupin III is now in his 20s as the ongoing saga of his adventures continues. This series finds him roaming through Italy and San Marino in search of rare objects to steal and beautiful women to seduce -- perhaps stealing their hearts. As he prepares to get married, it is revealed that the marriage is a sham and that it was set up as a way for Lupin to steal the Royal Crown of Liberty, which is just one of a number of precious items that he plans to take as part of his heists while in Europe.
