Description
For audiences of the Latin Spanish dub of the first Lupin III television series and the film The Castle of Cagliostro, the character known as Daisuke Jigen is referred to as Julián. He is a master marksman and the most consistently seen partner of the gentleman thief Arsène Lupin III. While his portrayal varies across different adaptations of the franchise, his role in the film The Castle of Cagliostro establishes him as a crucial and reliable ally to Lupin.

In The Castle of Cagliostro, Jigen, or Julián, has been traveling with Lupin for about a year. The story begins with the pair successfully robbing a casino in Monaco, only to discover their haul is counterfeit money. Jigen listens as Lupin recognizes the bills as originating from the small, mysterious duchy of Cagliostro, the site of a previous nearly fatal adventure for Lupin. During their journey, they witness a car chase and rescue a young woman, Clarisse, from her pursuers. After a crash leaves Lupin injured and Clarisse recaptured, Jigen helps his partner recover. He then joins Lupin and their associate Goemon Ishikawa XIII in a plan to infiltrate the Count of Cagliostro's fortress. Jigen participates directly in the heist, sneaking into the castle through its aqueduct and later engaging the Count's soldiers in a gunfight to provide a distraction. Following the adventure's conclusion, he drives away from the castle with Lupin and Goemon.

The character of Jigen is known for his laconic and subdued personality, which stands in contrast to Lupin's more flamboyant and impulsive nature. He often acts as the pragmatic anchor of the group, serving as the "voice of reason" and expressing cynicism or disgust toward Lupin's more reckless decisions, particularly his enthusiastic pursuit of women. Beneath his gruff and sometimes short-tempered exterior lies an ironic sense of humor and a genuine loyalty to his partner. Despite his complaints, he willingly participates in the most dangerous schemes and worries about Lupin's safety, even if he rarely shows it openly. His distrust is particularly directed at Fujiko Mine, the self-serving femme fatale who frequently complicates the gang's plans.

Jigen's motivations are inherently tied to his partnership with Lupin. As a professional thief and expert gunman, he is driven by the thrill of the heist and a commitment to his colleague. While other versions of the character explore a darker past as a mob hitman, in The Castle of Cagliostro he is presented as a seasoned and capable partner who works on a fifty-fifty basis with Lupin, not as his inferior. His primary role within the story is that of the reliable support, a master of combat and infiltration who handles the physical dangers that allow Lupin to focus on the cunning strategy and the central goal of rescuing Clarisse.

The defining relationship for Jigen is with Lupin, to whom he is unwaveringly loyal. Their dynamic is that of old friends and equals who bicker like an old married couple but trust each other implicitly. The film shows a subtle development in his character compared to earlier series, as he matures from being openly hostile when Lupin shows interest in a woman to being more understanding. At the film's end, he remarks on how nice Clarisse was and kindly suggests Lupin stay with her, demonstrating a growth in his perspective. His other key relationships include that with Goemon, whom he respects as a fellow warrior, and the bumbling Inspector Zenigata, whom the gang often uses as an unwitting distraction.

Jigen's most notable abilities center on his unparalleled skill with firearms. He is capable of a 0.3-second quick-draw and possesses a borderline superhuman accuracy, able to shoot targets with incredible precision using his signature Smith & Wesson Model 19 revolver. He uses his characteristic fedora hat not just for a mysterious appearance but also as a tool for aiming and target acquisition. Beyond his marksmanship, he is a proficient driver and pilot, able to operate virtually any vehicle, and a tough hand-to-hand combatant capable of disabling an opponent with a single blow. He is also adept at using disguises and is, by far, the most pragmatic and lethally efficient member of Lupin's gang, with the least apprehension about taking a life when necessary.
