峰不二子
is the grandson of Arsène Lupin. He is the world's most wanted thief and a genius mastermind. He is an expert in making schemes and plots to steal precious objects that are heavily guarded and seemingly impossible to be stolen. He sometimes appears incompetent, but mostly as a charade to catch his opponents off guard. While he has been arrested and thrown in jail on a number of occasions, he has always managed to break out. He also has a fondness for fancy gadgets from time to time. His infatuation with women, and Fujiko Mine in particular, is perhaps his biggest weakness, as it often lands him in undesirable situations.
