Ran Mori (also known as Rachel Moore in some English adaptations) is a central character in the Detective Conan franchise, including the film *The Scarlet Bullet*. She is the daughter of private detective Kogoro Mori and lawyer Eri Kisaki, who separated when she was seven years old; reuniting her parents remains an enduring goal. Her closest childhood friend and romantic interest is Shinichi Kudo, whom she met in preschool. Their bond solidified when Shinichi protected her from a kidnapping plot by their teacher. At age ten, witnessing national karate champion Satoru Maeda sparked her interest in the martial art, leading her to become captain of Teitan High School's karate club and a regional champion.
A pivotal event occurred during a trip to New York with Shinichi at sixteen. She encountered Vermouth, a member of the Black Organization disguised as a serial killer. Despite the danger, Ran saved Vermouth from falling to her death, earning the nickname "Angel." This act influenced Vermouth's later reluctance to harm Ran or Conan Edogawa (Shinichi's altered form). During this trip, Ran realized her romantic feelings for Shinichi. After Shinichi's transformation into Conan, Ran took him into her home under the guise of a distant relative, treating him as a surrogate younger brother. She has repeatedly suspected Conan's true identity but has been consistently misdirected by alibis orchestrated by Conan and his allies.
Ran's personality blends compassion, patience, and protectiveness with a strong sense of justice. She values life profoundly, exemplified by her refusal to let police snipers shoot a hostage-taker at her father's agency. She handles household finances, cooking, and chores due to her father's irresponsibility. However, a hot-blooded streak emerges when loved ones are threatened, often leading her to use her karate skills impulsively—a tendency causing near-miss misunderstandings. She remains calm when threatened with firearms or trapped in fires but harbors an intense fear of the supernatural, causing her to freeze in horror-related situations. Her loyalty leads her to wait for Shinichi's return despite the emotional strain, though she struggles to express her feelings directly.
In *The Scarlet Bullet*, Ran attends the unveiling of the "Hyper Linear" superconducting train during the World Sports Games (WSG) in Tokyo. She accompanies Conan, Ai Haibara, and the Junior Detective League to a pre-event party where sponsors are targeted. When a blackout occurs, she assists in locating the kidnapped sponsor Shiro Suzuki. Later, joining the group selected for the train's maiden voyage, she orchestrates a plan to redirect the Junior Detective League to a safer activity (a Kamen Yaiba show) upon learning of potential dangers. During the trip, she is caught in an MRI sabotage incident at Nagoya Airport, where vaporized helium renders her unconscious. She participates in subsequent efforts to protect the sponsors.
Ran possesses exceptional physical abilities. She holds at least a third-dan black belt in karate, with skills acknowledged by world-class martial artist Makoto Kyogoku. Her strength is notable—she scored 400 psi on a punching machine, outperforming trained boxers. She exhibits high agility, parkour proficiency, and resilience, enduring impacts like a steel baseball bat strike unharmed. She also displays deductive capabilities, having solved cases independently and noticed subtle inconsistencies. Her proficiency extends to household management, cooking, sewing, gambling luck, and musical talents like perfect pitch.
Ran is fair-skinned with bluish-purple eyes and long, dark brown hair styled with a distinctive triangular bang. She stands 165 cm tall with an athletic, curvaceous build. Her appearance often draws modeling offers, though she remains humble. She favors practical items like flip phones over smartphones and cherishes a sea cucumber strap on her phone—a gift from Shinichi replacing one he accidentally destroyed. Her clothing typically coordinates colors between her shirts and socks when not in uniform.
Trivia includes her childhood promise to designer Fusae Campbell to purchase one of her purses, fulfilled in later episodes. She was scouted as a reader model in Chapter 882. She experiences motion sickness when reading in vehicles and once bought a cake portion large enough for two people, consuming it alone.
