Is It Wrong to Be a Gangster in the World of Conan?

I traveled through Detective Conan and activated the gang system. I wanted to develop in a low-key manner, but the system issued a mission: to wipe out the black organization within three days. Looking at Gin's silver hair in the mirror, I silently took out the RPG. Mouri Kogoro was so frightened that he fell off the detective chair, and Officer Megure shouted that he wanted to give me a pennant. Just when I was about to retire, I heard the system prompt: "New mission: Become the king of the underground world..." Wait, that kid named Edogawa Conan, can you please stop looking so sharp?
