I Turned Traitor with Gin

My childhood friend and I were living peacefully in the organization. Then one day... BOSS: Go undercover. Me: No! BOSS: You have to. (No discussion.) My childhood friend: ... And so we went to the police academy. On the first day, we met two troublemakers. Somehow, they dragged my childhood friend and me into their mess. We had been told to keep a low profile: ... From then on, keeping a low profile was the last thing we did. My childhood friend hated those guys. Time and again, he shot them murderous looks. The other guys never sensed the danger at all. They just thought my childhood friend was scary, while I often sent them sympathetic looks behind his back. By the time we graduated from the police academy, we had pretty much figured out that two of those guys would go undercover. My childhood friend: Hah. If they join the organization, I'll be the first to report them. Later, when my childhood friend really did see a certain blond man with dark skin during a mission: ... Without the Gin who should have become a tireless worker, the distillery went from bad to worse. Meanwhile, Kudo Shinichi remained all over the newspapers. The distillery was still missing one of its silver bullets. My childhood friend and I watched as the distillery teetered on the brink. As it happened, we came across a manga. In it, Gin had to outwit the protagonist Conan and a whole bunch of other good guys, while surrounded by a bunch of useless undercover agents. My childhood friend: ... So I grabbed my childhood friend's itching-to-act hand. "Kurosawa, why don't we give him a hand and push him over the edge? This distillery is doomed!" Thanks to my childhood friend and me, we successfully went from undercover agents sent by the organization to FBI informants, secret Public Security collaborators, and the Tokyo Metropolitan Police Department's best partners... Reader's Guide: 1. The police academy group may not all be saved. The protagonists don't become especially close friends with them, since their identities and personalities make that difficult. 2. The characters may be somewhat out of character. 3. No romance, just friendship. 4. Kudo will still be shrunk. That hit still has to come from Gin. 5. In my headcanon, Gin is the same age as the police academy group. Otherwise, how could they be classmates? Haha. Shuichi is three years older than Gin. Theme: Keep working hard for a better life.
