Ran Mōri anchors all official media as the sole child of private detective Kogoro Mōri and lawyer Eri Kisaki. Her parents' separation when she was seven fuels her enduring quest to reunite them. Kindergarten introduced her to Shinichi Kudo when he requested her handmade sakura name badge. At six, she and Shinichi infiltrated Teitan Elementary to investigate supernatural rumors, encountering an unidentified figure who delivered a coded message.
Karate captivated her at ten after witnessing champion Satoru Maeda. By sixteen, she captained Teitan High's karate club, clinching regional titles. Approximately a year before Shinichi’s transformation, a New York trip proved pivotal: FBI agent Shuichi Akai (later revealed as Vermouth disguised as a serial killer) warned her and Shinichi. When Vermouth nearly fell to her death, Ran instinctively rescued her despite the peril, earning the moniker "Angel" from Vermouth and cementing Ran’s romantic feelings for Shinichi.
After Shinichi vanished from Tropical Land, Ran welcomed Conan Edogawa—Shinichi’s shrunken form—at Professor Agasa’s urging, treating him like a younger brother. She has repeatedly suspected Conan’s identity but faced consistent diversions through alibis from Conan and allies. Her relationship with Shinichi endures emotional strain from his absence, yet she waits faithfully, honoring his promise to return and respecting his undisclosed "important case."
Physically, she possesses a fair complexion, bluish-purple eyes, and long dark brown hair with distinctive wavy bangs forming a triangular point. Standing 160-165 cm tall with an athletic build, her martial prowess includes black-belt karate and judo proficiency learned from her father. She exhibits extraordinary strength—prying open elevator doors or scoring 400 (and breaking) a punching machine—coupled with high agility through parkour and precise kicks. Her reflexes enable bullet dodging and deflecting falling objects.
Kindness, patience, and fierce protectiveness define her, though provocations unleash a formidable temper. She values all life, evidenced by saving Vermouth and halting police snipers from shooting a hostage-taker. While brave against physical threats, supernatural elements trigger paralyzing fear. She manages household finances, cooking, and cleaning due to her father’s irresponsibility, often mediating his professional interactions.
Ran remains oblivious to male attention, rejecting advances out of loyalty to Shinichi, though she struggles to voice her feelings directly. Beyond combat, her skills span sewing, cooking, singing, piano, and functional English. She displays uncanny luck in games of chance and has independently solved three cases using observation and memory. Nicknames include "Angel" (Vermouth) and "Ranmaru" (Hina Wada).
