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.

While Fujiko is not part of Lupin's gang, she often participates in their exploits either as a partner or a competitor. Her main tactic is to stick with Lupin and company until the plunder is made available, then double-cross her colleagues. Frequently, as the very definition of a femme fatale, she finds it necessary to betray Lupin to get close to the enemy, then after ingratiating herself into his trust will acquire the swag and escape (rarely, she will help to extricate Lupin, Goemon and Jigen from capture or any deadly trouble she put them into, as if to atone). Fujiko is also known to provide Zenigata or other law enforcement officers with information and assistance in order to gain her own freedom. At one point, Fujiko was made Zenigata's replacement on the ICPO's Lupin operation, but this was a cover for her to get into a secret vault.

Of this two-faced nature Lupin is surprisingly forgiving. In the 1999 television movie Da Capo of Love: Fujiko’s Unlucky Days, Lupin carefully treats the amnesiatic Fujiko, hoping she gets better as he "looks forward to her betrayals".

Fujiko is an excellent markswoman, her favorite weapon being a Browning M1910, typically holstered in her garter. Later, she's revealed superb martial arts skills, capable of rendering an attacker twice her weight unconscious with a single blow. She is very good at disguises as well as accents and apparently can speak dozens of foreign languages in addition to her native Japanese. Like the other members of Lupin's team, she is able to pilot virtually any land, sea, and air vehicle, with her personal preference being a conventional Kawasaki motorcycle. She can be very promiscuous when necessary to complete a job, and has kissed and even had sex with different men for information or to escape a dangerous situation. The 2012 anime series implies heavily that Fujiko is bisexual or it could be that this is simply another means of getting what she wants, as her current orientation has not been clarified.

Daisuke Jigen despises Fujiko and sees her showing up as a sign of rough times ahead, although despite this, in the original manga he was still one of her suitors. Goemon Ishikawa XIII, who had a brief romance with Ms. Mine, has been known to work on capers with Fujiko independent of the other gang members, but can be equally distrustful of her when he thinks she is manipulating Lupin. Still, in the Lupin the Third Part II anime Jigen and Goemon are seen working together numerous times with Fujiko, trusting their lives on her, and vice versa, with them having a sibling rivalry of sorts. In the anime, Fujiko also displays at times a more frivolous and care-free personality, which sees her pranking Lupin whenever she can.

Lupin is completely infatuated with Fujiko, and will do anything for her. While Fujiko is aware of this and always uses it to her advantage, she never gets Lupin into trouble where he cannot escape. Monkey Punch has said that the two "enjoy each other", and are quite content with their bizarre yet amicable relationship, comparing it to his own marriage.

Although she is more willing to contain her feelings, Fujiko does have a love for Lupin. She rarely wishes to fully reveal her affection except if she thinks one or both are dying. On occasions where Lupin appears to have died, she grieves and considers him the most important person to her. However, her not-altogether-hidden feelings submerge again when she finds him alive.

Fujiko usually dresses in the height of fashion, with formal gowns and fine jewelry her trademark; when informal, she typically wears outfits that accentuate her robust figure. Fujiko's favorite pastimes appear to be shopping, attending social functions, disco dancing, horseback riding, and dating wealthy gentlemen. She enjoys champagne, fine wine and has been seen more than once consuming a martini; she also smokes cigarettes and occasionally uses a kiseru.
