Fujiko Mine

Fujiko is Lupin's love (or lust) interest. Fujiko is an extremely intelligent and crafty person and will use her feminine charms to get what she wants from any man. She is also an expert when it comes to firearms and even rivals Lupin when it comes to her burglary skills. Lupin and Fujiko were never really lovers although occasionally Lupin scored with Fujiko, especially when the latter is dying to find out about a particular detail that Lupin knows. She will also routinely make deals with Zenigata or Lupin's current enemy in an attempt to gain her freedom or to hopefully gain a piece of the loot he is after. While Lupin normally is able to outsmart Fujiko, she is able to make off with some or all of his loot on occasion. She doesn't like frogs (Source: Wikipedia)
