In Detective Conan, Kim's real identity is not a policeman. King is an important member of the black organization. Gin wears a black trench coat and has long silver hair (gold in early animation). His face is always covered with hats and bangs. He was cruel and calm, and seemed to kill anyone without hesitation.

Frequent assassinations and the removal of traitors in the organization are the chief culprits who poured APTX4869 into Kudou Shinichi to make it smaller, and also one of Conan's main enemies.

Extended data:

Gin is mature and cautious, ruthless, suspicious and heartless. He was once described as "as if he killed many people and didn't care". He often carries out various assassination missions. He didn't hesitate to kill. He will kill people who know the secrets of the organization without mercy. Even he can be cruel to himself, claiming that he "never remembers the faces and names of the people who were killed".

Gin has a strong loyalty to Boss and the organization, and hates traitors very much. Once a traitor is found, he will be eradicated at all costs, leaving no trace. In the early days, he was a big brother figure, but in the middle and late period, his personality was constantly enriched by G?sh? Aoyama and he became an all-round killer integrating reasoning, ruthlessness, sniper and leadership.
