Ran Mōri, daughter of private detective Kogoro Mōri and lawyer Eri Kisaki, experienced her parents' separation at age seven, fueling a persistent longing to reunite them. She shares a profound childhood friendship with Shinichi Kudo that blossoms into mutual romantic affection, deeply shaping her personal choices and emotional fortitude. Her personality blends genuine care for loved ones, remarkable patience, kindness, and a strong idealistic sense of justice. Ran demonstrates exceptional bravery, confronting armed assailants or rescuing others from danger without hesitation. Yet, she harbors an intense, irrational fear of the supernatural and horror. Protectiveness often triggers impulsiveness, sometimes leading to misunderstandings due to her readiness to employ physical force. A black belt and captain of her high school karate team, her martial prowess rivals professionals, granting considerable strength, agility, and lightning-fast reflexes. These skills enable feats like prying open elevator doors or evading falling objects. Domestically, Ran shoulders household responsibilities for her frequently irresponsible, alcoholic father and Conan Edogawa, managing finances, cooking, cleaning, and client接待. She also exhibits proficiency in sewing, singing, piano, and English. Notably, her extraordinary luck in games of chance and gambling remains unbroken. Following Shinichi Kudo's disappearance, Ran takes in Conan Edogawa—Shinichi's transformed identity—believing him a distant relative. She develops a surrogate sibling bond, overseeing his welfare while occasionally suspecting his true identity due to uncanny behavioral echoes of Shinichi. These suspicions surface multiple times, such as witnessing Conan's deductive skills or noticing physical similarities, though plausible alibis repeatedly resolve her doubts. One instance involved discovering Conan's phone vibrating moments after emailing Shinichi, yet failing to locate the email on his device. In the "Stranger From 10 Years Later" narrative, a decade into the future, Ran faces a marriage proposal from Dr. Araide amid societal pressure and Shinichi's prolonged absence. She retreats to the Kudo family library, a place rich with memories of Shinichi, to contemplate her feelings. Confronted by a temporarily aged 17-year-old Conan claiming to be Shinichi and begging her not to marry, she rejects his identity assertion but staunchly reaffirms her commitment to wait indefinitely: "I’ve already waited ten years... so another ten will be just fine," visibly emotional. This underscores her unwavering loyalty and willingness to endure prolonged emotional hardship. Key experiences shape her past: a New York trip with Shinichi led to an encounter with Vermouth (disguised as a serial killer). Ran saved Vermouth from a fatal fall, earning the moniker "Angel" and inadvertently securing Vermouth's later reluctance to harm her or Conan. This incident also crystallized Ran's realization of her love for Shinichi. Other formative events include meeting Fusae Campbell in childhood and developing an interest in karate after witnessing champion Satoru Maeda compete. Physically, Ran possesses fair skin, long dark brown hair with distinctive wavy bangs, and bluish-purple eyes. Standing approximately 160–165 cm tall, she maintains an athletic, curvaceous build. Her acknowledged beauty attracts modeling scouting attempts and frequent romantic attention from men, which she typically overlooks due to her focus on Shinichi. Ran resolves three cases independently, demonstrating deductive abilities when personally motivated, such as defending a wrongly accused idol or classmate. Her name carries a self-referential pun, associating "Ran" with the English word "run," reflecting her energetic nature.
