Gender: Male The second-in-command of the Black Organization and the boss's closest aide. A cigar aficionado. Considered a top-secret existence alongside the boss; most members with code names, including Vermouth and Vodka—let alone Rye or Sherry—have never met him. Very few know his true identity. Rumors about his appearance vary wildly: a "strong, hulking man," a "feminine man," or an "old man," with some suggesting these are all body doubles. However, all rumors agree he is "missing one eye," having lost it in a past accident and replaced it with a prosthetic. Gin has met Rum personally and knows his current movements. According to Gin, only the prosthetic eye is a true characteristic, while the rest is misinformation spread by Rum for protection. Vodka also mentions that Rum has changed his face and taken a silly name. Consequently, Vodka refers to him as "Master Rum" based on intel, and Chianti once asked him if he had ever seen Rum's face.

Gender: Male A high-ranking executive of the Black Organization who communicates directly with the boss ("That Person"). Extremely cold-blooded with sharp observation and insight, he ruthlessly eliminates anyone who might become an obstacle to the organization. His car is a Porsche 356A.

Gender: Male Responsible for field operations and undercover investigations within the Black Organization. He is Gin's subordinate and constant companion. As one who knows the organization's terrors firsthand, his loyalty is unwavering. He displays thorough ruthlessness when necessary. He looks up to Gin and calls him "Aniki" (Big Brother).

Gender: Female A direct subordinate who is specially favored by the boss. A master of disguise, she has impersonated various people to search for Sherry. Although she has deduced the true identities of Conan and Haibara, she keeps this a secret from the organization for unknown reasons. She is highly multilingual and a skilled marksman, but her greatest asset is her disguise ability. Known by enemies as the "Witch with a Thousand Faces," she can impersonate anyone regardless of gender, excelling in intel gathering, psychological warfare, and disguising others. Her speech combines adult allure and mystery, using feminine sentence endings like "-wa" or "-janai?" while occasionally showing a cold, composed side. She refers to herself as "Watashi" or "Atashi."

Gender: Male Known as "Bourbon" in the Black Organization, he excels at information gathering. His true identity is Rei Furuya, an officer of the Public Security Bureau's "Zero" division. His role in the organization is a "detective/investigator." Kir describes him as terrifyingly skilled in observation and insight, and Vermouth calls him the organization's top intellect. However, some members resent his secretive nature and refusal to show his hand. He often operates alongside Vermouth. Because he focuses on espionage, he is less frequently involved in bloody conflicts compared to other members, yet he makes cold-blooded decisions depending on his goals or the situation.

Gender: Female A popular announcer for Nichiuri TV. 27 years old. Blood type AB. Though initially thought to be a member of the Black Organization under the code name "Kir," she is actually a CIA undercover agent. Her mission was to introduce a new contact to her father, Ethan Hondo (also a CIA mole), and fake her own death to leave the organization. However, four years ago, she failed to notice a transmitter on her person, leading her father to choose death to save her. Thanks to her father's prior setup, she avoided suspicion and even earned her code name through the incident.

Gender: Male A sniper for the organization, like Chianti. Taciturn and composed. He shows a cold-blooded side, carrying out murders silently. Like Chianti, he dislikes Vermouth.

Gender: Female Short-tempered and bellicose. She hates Vermouth enough to say she'd "put a bullet in her without hesitation" if she weren't the boss's favorite, resenting her for using and abandoning Calvados. In the 13th movie, "The Raven Chaser," she calls Detective Wataru Takagi a "cute boy," suggesting she is in her late 20s or older. She refers to herself as "Atai." Her car is a blue first-generation Dodge Viper, and her rifle of choice is a PSG-1. She is also a professional helicopter pilot.

Gender: Male The code name given to FBI agent Shuichi Akai during his time undercover in the Black Organization. Like other executives, it is named after a liquor—specifically, rye whiskey. He operated as a sniper.

Gender: Male The true identity of "That Person" who reigns at the top of the organization is the billionaire Renya Karasuma, who was thought to have died. He was a powerful figure in politics, finance, and the underworld, said to be over 100 years old forty years ago. While his name was revealed through the dying message of pro shogi player Koji Haneda, his persona remains shrouded in mystery. His face is unknown, but his silhouette features long hair and a prominent nose. He holds a cane in his right hand and has a crow on his left shoulder. His crest is a crow. He trusts Guest immensely, granting them almost total freedom.
