Conan: The Machinist

This story focuses on scientific accuracy and logic. The writing style is initially clumsy, but improves significantly after around 120 chapters. Romance becomes more prominent after chapter 380. The story begins in March 1994 and features a single female lead, Ai Haibara. The plot largely avoids confrontations with the Black Organization and the FBI, concentrating instead on the protagonist's relationship with Ai Haibara. The timeline follows real-world history, with meticulous attention to detail, aiming for realism and credibility. Don't expect any unscientific elements; even if they appear, they won't affect the protagonist.
