My Organization Passed the Civil Service Exam

Tsukishiro Chihiro transmigrated, and when he opened his eyes, there was a dead man in front of him. Bad news: I killed him, and the evidence is airtight. Good news: The deceased doesn't exist in any meaningful sense, so I won't go to prison. Before he could decide whether to turn himself in, there was more. Good news: The eyewitness is willing to cover for him, and even took the initiative to dispose of the body. Bad news: The deceased was named Renya Karasuma, and the eyewitness was named Gin. On his very first day transmigrating into the Detective Conan world, Tsukishiro Chihiro was forced to take over as the boss of the Black Organization. He also got himself a bottle of baby Gin. From then on, he led the organization's employees at a breakneck pace down the broad road of career transformation. But... why were the two bottles of fake whiskey who'd infiltrated the organization so weird? They even corrupted the other bottle of real liquor he'd brewed himself! During the Red and Black arc, Akai faked his death under Kir's gun. When he opened his eyes, he found himself lying in the middle of the road, while Akemi, who looked like she'd come straight from hell, stood in front of him with a ferocious expression, calling the police: "Officer, come quick! Someone's faking an accident!" At the moment of his rooftop suicide, Hiromitsu's vision blurred. The hole in his chest was gone, and there was a sniper rifle in his hands. Not far away, a certain codename holder, officially deceased, was fleeing from the police. His earpiece crackled with his childhood friend's cheerful voice: "Scotch, what are you doing? He's getting away! Just shoot him in the leg, don't kill him. Gin said to hand him over to the police. He still has a statement to give!" After seven years of going up against the Organization, Rei died of overwork from having too many jobs. When he opened his eyes again, he was back at the age when he first went undercover in the Organization. His ambitions soared: With the script in hand, this time he'd take down the Organization early. There wouldn't be so many sacrifices, and Hiro would live! But in the blink of an eye, he got a call from the Organization's top killer: "Bourbon, the boss wants you to take the civil service exam. Have you practiced the questions? If you're not confident, the boss hired you a tutor, a top graduate of the University of Tokyo's law department. What was his name... Kongming, I think." Tsukishiro Chihiro: "...Um, Koto-chan, come with me to find our Bourbon. We can play with the kid while we're at it." Conan from the original world: "???" Gin: "...Fuck, why am I the only one who got shrunk when we crossed worlds?" Tsukishiro Chihiro: "!!! Little Koto-chan, kawaii~ Come here, let me hug you~" Gin: "Die!" "We share a secret. We entrust our lives to each other, becoming each other's indispensable other half. We are accomplices." Tsukishiro Chihiro Pairing: Gin. The top and bottom may not be clear, but please treat the original character as the top. To avoid arguments over whose perspective this is, I've changed it to top-focused for now.
