Gender: Male The boss's right-hand man and the second-in-command of the Black Organization. A lover of cigars. He is considered a top secret on par with the boss; even members with code names like Vermouth and Vodka, let alone Rye or Sherry, have rarely met him, and very few know his true identity. There are numerous rumors regarding his identity, such as a "sturdy giant," a "feminine man," or an "old man," with some suggesting these are all body doubles. However, it is consistently rumored within the organization that he "loses one eye" and has a prosthetic eye due to a past accident. Gin has direct contact with Rum and knows his current movements. According to Gin, the only true characteristic is the prosthetic eye, and the rest is false information spread by Rum for self-protection. Furthermore, Vodka mentions that Rum changes his face and uses a silly alias. Because of this, Vodka refers to him as "Boss Rum" based on information, and was once asked by Chianti if he had ever seen Rum's face.
