Tequila is a tall intimidating member of the Black Organization that is used to muscle people into making deals with his syndicate. He apparently comes from Osaka since he is heard to speak with a Kansai accent. He first appears in Volume 12 of the manga (episode 56 of the anime) where Conan literally bumps into him at a video game convention in a hotel. At first, Conan only dismisses him as being a game company employee when he sees him pick up a suitcase with a game company's logo on it.
