Description
Goemon Ishikawa XIII is the thirteenth generation of a renegade samurai family, directly descended from the historical outlaw Ishikawa Goemon. In the Spanish dub of the series, he is referred to by the name Ramón. A man of few words and deep reserve, Goemon presents a stark contrast to the boisterous and irreverent Arsène Lupin III. He is a master of several classical Japanese martial arts, including Kenjutsu, Iaidō, Jujutsu, Karate, and Aikido, and carries an unwavering devotion to the samurai code of honor. His appearance is traditional, almost anachronistic, as he is almost always seen wearing a hakama and a kimono, the colors of which have varied over time, and his long, unevenly cut black hair frames a face that is typically stoic and unreadable. This quiet exterior, however, contains a profound sense of pride in his abilities and a fierce inner world of discipline and emotion.

Goemon is an expert in a variety of extraordinary skills. His most famous possession is the Zantetsuken, an indestructible katana of legendary sharpness capable of slicing through virtually any substance, including steel, bullets, automobiles, and even entire buildings. Despite the sword's lethal potential, Goemon strictly prefers to incapacitate rather than kill. He will often disarm or humiliate his opponents by using his blindingly fast strikes to cut through their weapons or slice their clothes to ribbons. After such non-lethal displays, he almost always laments his actions with his famous catchphrase: "Once again, I have cut a worthless object". Beyond his swordsmanship, his martial arts training grants him phenomenal physical prowess, including the ability to catch arrows or thrown daggers with his bare hands, control his breath for long-distance underwater swimming, and withstand extreme cold. He is also a talented spy, a skilled driver and pilot, though he prefers not to take the wheel, and is proficient in the global art of disguise and impersonation.

Goemon's deepest motivation is the continuous pursuit of self-perfection and the refinement of his warrior spirit. His loyalty to Lupin and the gang is strong, but it is conditional upon his personal morals. He will readily assist in any heist that he deems just or honorable, but he will just as quickly oppose Lupin if a job violates his strict ethical code. This sense of honor is so extreme that he feels profound shame and remorse when he fails at a task, such as when his sword has been broken or stolen. In these moments of disgrace, he will often isolate himself to meditate or undergo harsh training to purge his perceived weakness. While he can appear aloof and humorless, he is not without comedic failings, which often stem from his traditional upbringing. He is notoriously bad with money, easily falling for scams that promise spiritual enlightenment, and he has a deep, almost childlike vulnerability when it comes to women, trusting those who seem innocent and becoming flustered or fleeing from those who are more forward.

The dynamics of his relationships define his role in the story. His bond with Lupin is complex; what began as a deadly rivalry in the original manga has matured into a deep, loyal friendship. However, Goemon is often annoyed by Lupin's impulsiveness, his obsession with Fujiko Mine, and his generally unserious nature. So great is his commitment to his own code that he has even sworn that his final act in life will be to deliver the deathblow to Lupin himself. In contrast, his relationship with Daisuke Jigen is one of mutual, quiet respect. Goemon sees Jigen as a fellow warrior, while Jigen trusts Goemon as a reliable partner, and the two are frequently paired together on missions to both help and restrain the unpredictable Lupin. He maintains a deep but wary relationship with Fujiko Mine, having initially been her boyfriend in the manga. While he generally distrusts her manipulative nature, he is willing to ally with her when their goals align and he is confident she will not betray him.

Goemon's journey from a foe to a trusted ally is a key part of his background. In his first manga appearance, he was a dangerous enemy who tried multiple times to kill Lupin, including hiring Jigen as an assassin. His allegiance changed when he came to respect Lupin's skills and after Lupin helped him avenge the murder of his uncle. This core narrative has been adapted and altered across different anime series, but the central theme of an honorable warrior finding a unique place among thieves remains constant. Despite his disciplined demeanor, Goemon has faced strong personal connections. He was engaged to Murasaki Suminawa, the daughter of a ninja clan leader, but broke off the engagement believing himself unworthy of her. He has also been betrayed by childhood friends and love interests, which reinforces his guarded view of the world.

Ultimately, Goemon Ishikawa XIII, also known as Ramón, serves as the soul of the Lupin gang. He is the moral counterweight to Lupin's hedonism and Jigen's pragmatism, a master swordsman in a world of machine guns and getaway cars whose presence reminds the audience that even a band of thieves can operate with a sense of profound, ancient honor.
