Vodka

Vodka is a member of the Black Organization who is often seen by Gin's side. His official position is that of secretary in the general oversight division, so he handles most of the research and information for the duo, such as setting up meetings (309-311), and relaying information to other members (54, 345). Vodka is often seen using some transport.

Vodka speaks and acts like a typical mafia or Yakuza type gangster, and he is just as ruthless a killer as his partner Gin. However, he is also more easy-going and trusting than the latter, thus making him more susceptible to traps Conan sets to apprehend the Organization. In addition, he tends to not perform well under stress without guidance from Gin or other characters.
