The grandson of Arsène Lupin is tall, lanky, impertinent, and very sneaky. His prime qualities are listed as "appearing like a god, disappearing like a demon"; in other words, he appears with a flash and leaves with a whisper. Despite being aided by many gadgets, his main talents lie in plotting and evasion of weapons.
Little is known about Jigen's past; while he is listed as a Japanese national, it is believed that he fled to Japan and changed his name to avoid the American mafia. While his primary function is bodyguard and hitman, he has become Lupin's closest ally. His black suit, black fedora, and beard easily identify him. The ever present black fedora also serves as an sighting aid enabling Jigen to be a precise, quick (clocked as having a 0.3 second fast draw), and deadly shot.

Mine Fujiko is a beautiful thief that few men, including Lupin, can resist. Her primary modus operandi is use her feminie wiles to get close to the same treasure that Lupin is after.

Normally, Lupin does outsmart Fujiko, but she also makes away with the loot on occasion.
Zenigata Keibu (Keibu translates as "Inspector") is an incredibly diligent yet incredibly gullible policeman whose life has been dedicated to bringing Lupin to justice. While he has some interest in capturing Jigen, Goemon, and Fujiko, he is really after only Lupin. Zenigata belongs to the esteemed ranks of law enforcers doomed to never successfully catch their man. Originally a member of the Tokyo Police Force, Zenigata was transferred to Interpol to allow him to travel the globe after Lupin. His obsession has unfortunately put a strain on his marriage and his relationship with his daughter Toshiko.
