Description
Daisuke Jigen serves as the primary marksman and loyal partner to Arsène Lupin III. Born in the Bronx, New York, he joined the New York mob young before relocating to Europe and the Italian mafia. There, he grew close to his boss's wife, Cicciolina. When the boss tried to kill him, Cicciolina intervened, accidentally killing her husband. Jigen arrived, took the gun from her hands, and claimed responsibility to protect her. This weapon became his signature Smith & Wesson Model 19 revolver, his most prized possession alongside his trademark fedora. Fleeing the Italian mob, he joined the rival Chinese mafia. Cicciolina later hired Fujiko Mine to steal Jigen's Magnum, leading to a church confrontation where Cicciolina pointed the unloaded gun at Jigen. He shot her, only realizing she sought assisted suicide. This event prompted his abandonment of killing and transition into theft.

Jigen's personality blends pragmatism, cynicism, and deep loyalty. He frequently questions Lupin's impulsiveness and distrusts Fujiko Mine due to past failed romances and betrayals. Despite this, he remains Lupin's steadfast partner, often acting as the reliable "big brother" providing reason. He shows minimal hesitation in taking lives when threatened but avoids harming women and children. A gruff exterior masks an ironic sense of humor and genuine enjoyment of heists. His habits include heavy smoking (around 60 bent cigarettes daily), drinking scotch or bourbon, and avoiding dentists despite chronic toothaches. Interests encompass American cuisine, boxing, spaghetti westerns, and target practice. He rarely socializes outside the gang and prefers staying home.

His appearance is defined by practical attire: typically a dark gray or black suit, light-colored dress shirt, black tie, and lace-up boots. His broad-brimmed fedora—usually gray or black with a band—shadows his eyes and is rarely removed except during mourning or formal events. He sports a chin curtain beard and unevenly cut collar-length hair. In *Lupin the 3rd Part 5*, his outfit is a dark gray suit, purple shirt, white tie, and brown boots, consistent with his minimalist style.

His skills center on firearms mastery, notably a 0.3-second quick-draw and near-superhuman accuracy with revolvers. He adeptly uses trick shots (like dropping chandeliers) and handles diverse weapons, including sniper rifles and anti-tank guns. He is proficient in hand-to-hand combat, vehicle operation, and disguises. In *Part 5*, during the Marco Polo arc, he executed a precise sniper shot to graze Lupin's head, aiding a deception using augmented reality technology, showcasing his tactical synergy with the gang.

Jigen's relationships are pivotal. His bond with Lupin, rooted in mutual trust and shared history, is occasionally strained by Lupin's recklessness but ultimately unbreakable. He respects Goemon Ishikawa XIII and maintains a wary, sometimes hostile, dynamic with Fujiko. His interactions with Inspector Zenigata reflect professional rivalry without personal animosity. In *Part 5*, his role is largely supportive, particularly in arcs involving the hacker Ami and Lupin's past associate Albert. Episode 19, "A 7.62mm Mirage," explores his history through a mercenary adversary, emphasizing his pragmatic approach to threats.

Character development across media shows evolution from the manga's initial portrayal as a cynical, opportunistic hitman to the anime's loyal partner. Early manga chapters depict him accepting contracts to kill Lupin, but later narratives solidify their friendship. *The Woman Called Fujiko Mine* offers a darker pre-Lupin backstory, highlighting his transition from mercenary to thief. *Lupin Zero* suggests a childhood connection with Lupin in 1960s Japan, though canonicity is unconfirmed. In *Part 5*, his consistency as Lupin's right-hand man underscores his role as the gang's stabilizing force, with minimal focus on his past outside mission contexts.
