Shinichi and Ran

d (Ran Mori) is Jimmy's childhood friend and canonical love interest.

They have known each other since as early as kindergartenand had been playmates since then, which caused some censure from Eva.

In junior high school, Jimmy turned down Asami Uchida, then the manager of the soccer team who admitted that she was interested in him, in favor of Rachel. Their classmates already considered them a married couple and jested about their platonic relationship now and then. There was even a time when he planned to admit his true feelings to Ran after he took a temporary cure for his condition, but he had to solve a murder in the restaurant he took her to, and then turned back into Conan before he could tell her anything. The waitress thought that he was going to propose.

When Jimmy disappeared at Tropical Land, Rachel took in Conan from Professor Agasa, not knowing that Conan was actually Jimmy. Jimmy/Conan decided not to tell Rachel or anyone else about his identity in the fear that the Black Organization might hurt or kill her and her family if his secret somehow got out.

Knowing that Rachel misses him, however, Conan calls her over the telephone and imitates Jimmy's voice with the voice-changing bowtie, so that she is not worried about him. He convinces her that he is off solving a very difficult case and will return once the investigation concludes.

Rachel is no fool however, and due to striking similarities between Conan and Jimmy as a child, she often suspects Conan of somehow being Jimmy. However, every time she does, Conan does something childlike to make her ignore the idea. Later, larger schemes created by Jimmy and those who know his secret have been used to convince Rachel that Conan is not Jimmy. These include pre-recorded messages from "Shinichi" played over the phone in addition to other more and more complex tricks that they pull off. This usually follows an extremely long story arc. In such arcs Conan tends to drop his guard in order to save someone, or to fully investigate a crime. Jimmy hates having to lie to her, and it takes a huge emotional toll on them both, but he loves her too much to let the Black Organization get anywhere near her.

In more recent stories, Rachel becomes positive of Conan's true identity and asks him to admit the truth. Sometimes, Jimmy feels that he cannot trick her anymore. Jimmy gets close to telling her, but then something usually happens which hinders him to do so. After his first encounter with Harley Hartwell (Heiji Hattori), Conan discovers the poison that was fed to him could temporarily be deactivated through drinking a very high proof Chinese alcohol called Paikaru. He makes this discovery when he temporarily turns back into Jimmy after Harley gives Conan some of the liquor as a kind of cold remedy.This is one of the three occasions when Jimmy turns back into his true form. Despite being separated from each other, Rachel and Jimmy still love each other very much and Rachel is always constantly waiting for Jimmy to return and remains faithful to him.

Jimmy/Conan is not without sexual fantasies regarding Rachel; the most obvious example being his getting nosebleeds or blushing--manga shorthand for lust-- when he sees her in a bathing suit, or when Rachel pulled him into an onsen43 with her.
