A high-ranking executive of the Black Organization, he is cold-blooded and never hesitates. Emotions are unnecessary when pulling the trigger, and his precision, which allows for not even a hair's breadth of error, possesses an icy chill. He disposes of people without mercy and issues orders decisively. He is a heavy smoker with waist-length silver hair and green eyes. He is surprisingly talkative. He never speaks kindly. He rarely laughs. He is extremely cold-hearted. He speaks in imperatives. Left-handed. A cool, hard-boiled man.

Dull and slow-witted with a large build, he is Gin's subordinate. He calls Gin 'Big Brother' and uses polite speech with him while using informal speech with other employees.

A woman of mystery. A glamorous blonde who frequently makes passes at Gin, though he does not reciprocate. She appears lighthearted but is highly capable. She is an expert in infiltration and disguise.

A man with blonde hair and dark skin. He has a sly personality and uses polite speech, yet he is cold-blooded and cruel. He appears to be quite a kind person.
