I am Gin, a hitman for the Black Organization.
I once went with my partner Vodka to an amusement park for a deal. While we were there, I also made Shinichi Kudo, who had been spying on the transaction, swallow APTX-4869. But on the way out, several moles within the organization joined forces to knock me out and force-feed me APTX-4869. When I woke up, my body had somehow reverted to its teenage state!
Not only that, I discovered that another "Gin" was still operating under my name within the organization. My subsequent investigation revealed that this was a spy from another organization, and there were quite a few of them.
To root them out, I took up residence in a shop called "Cat's Eye," with the Mouri Detective Agency upstairs. Vermouth is my inside contact in the organization, while Sherry, using the alias Ai Haibara, invents all sorts of handy medicines and gadgets suited to my current identity.
I'll deal with the traitors hiding within the organization myself!
Though I may have a teenager's body, my skills are beyond ordinary, and there's never just one mole in the organization! - Gin, the Killer
