Ran Mouri, a supporting character in the spin-off "Detective Conan: The Culprit Hanzawa," retains her established background from the main series. She is the daughter of private detective Kogoro Mouri and lawyer Eri Kisaki. After her parents separated when she was seven, she actively seeks to reunite them. Ran shares a close childhood friendship with Shinichi Kudo, dating back to kindergarten. Significant early events include sneaking into Teitan Elementary at night to investigate a monster rumor, encountering an unidentified individual who gave them a coded message. Approximately one year before the main series, a trip to New York saw Ran and Shinichi encounter the disguised Vermouth of the Black Organization. When Vermouth nearly fell to her death, Ran saved her despite the danger, earning Ran the nickname "Angel" from Vermouth; this trip also solidified Ran's romantic feelings for Shinichi. Following Shinichi's apparent disappearance after an incident at Tropical Land, Ran took in Conan Edogawa, introduced as Shinichi's distant relative by Professor Agasa. She cares for Conan like a younger brother while occasionally suspecting his true identity. As captain of Teitan High School's karate club and Kanto regional champion, she possesses formidable martial arts skills. She also manages household affairs for her father, handling cooking, cleaning, and finances due to his irresponsible behavior. Ran's personality blends kindness, patience, and protectiveness toward loved ones with a formidable temper when provoked. She intensely values justice and human life, demonstrated when preventing police snipers from shooting a hostage-taker at the agency. Despite bravery in dangerous situations like facing guns or fires, she harbors an intense fear of the supernatural and horror subjects. Largely oblivious to others' romantic attention due to her enduring feelings for Shinichi, his prolonged absence causes her significant emotional pain. She channels frustration through physical outbursts, often using martial arts to intimidate others, including her father, into compliance. Physically, Ran has fair skin, an athletic build, bluish-purple eyes, and long dark brown hair styled with distinctive triangular bangs. Her appearance attracts frequent modeling offers; one such offer involved painter Riko Rokui, who targeted models out of jealousy. When Rokui attempted a knife attack, Ran deflected it using her karate. Ran resolved the confrontation by revealing the painter's intention to resume working exclusively with Rokui, prompting the assailant's remorse. Her martial arts expertise in karate and judo grants her significant strength, damaging a 400-point punching machine and prying open elevator doors. She exhibits exceptional agility, coordination, and stamina, reacting swiftly enough to dodge a bullet at close range. Additional skills include household management, sewing, cooking, piano playing, singing, and fluent English. She possesses extraordinary luck in games of chance and sharp observational skills that occasionally assist in investigations. Within "The Culprit Hanzawa," Ran interacts briefly with the titular character during Hanzawa's misadventures in Beika City. Hanzawa develops a fear of her after witnessing her intimidating demeanor, particularly when dealing with her intoxicated father. Ran appears sporadically as part of the environment in this spin-off, her role ancillary and consistent with her established traits without additional development.
