Ran Mouri is known for her kind and caring nature, but she can also be fiercely protective and intimidating when angered. Her passionate personality often overwhelms those around her, though she remains patient, nurturing, and devoted to those she loves.

She deeply values life, even the lives of those who pose a threat to her own. This is demonstrated when, despite being threatened by the disguised serial killer Vermouth in New York, Ran doesn’t hesitate to save her when Vermouth is about to fall to her death. Similarly, when a hostage situation arises at the detective agency, Ran takes swift action to protect others by closing the curtains to prevent the police snipers from firing.

Though compassionate, Ran is also brave and resourceful. She has demonstrated calm, confidence, and quick thinking in dangerous situations, such as when threatened by a gun or surrounded by flames. However, she has an irrational fear of the supernatural and is not fond of horror, sometimes freezing in fear, as seen when attacked by a bandaged man.

Ran’s impulsive nature often leads her to act on emotion, especially when those she cares about are involved. She can quickly jump to conclusions, such as suspecting Shinichi of infidelity or believing her mother was having an affair after seeing a photograph with another man. When angered, she isn’t afraid to use her karate skills to defend her loved ones.

Independent and self-sufficient, Ran takes on much of the responsibility at the Mouri household, from managing finances to cooking and housework, especially given her father Kogoro’s irresponsible behavior. She also tries her best to reconcile her stubborn parents, though with little success.

Despite her beauty, Ran is humble and rarely uses her attractiveness to her advantage, often oblivious to the attention she receives from men. This causes some frustration for her best friend Sonoko, who believes Ran’s devotion to Shinichi is hopeless. Ran, however, remains steadfast, never entertaining other suitors and trusting in Shinichi’s promise to return to her.

Though strong-willed, Ran can be emotionally vulnerable. Shinichi’s absence causes her great emotional distress, and she continues to wait for him, refusing to make him choose between her and his important cases. Despite the pain of his absence, she holds onto the hope that Shinichi will keep his promise and return.

Ran Mouri is the childhood friend of Shinichi Kudo and the daughter of Kogoro Mouri and Eri Kisaki. She first met Shinichi in kindergarten when he asked her to give him a Sakura badge she had made.

As a first-grader, Ran accompanied Shinichi on a nighttime adventure to investigate a mysterious “hat-wearing monster” rumor at Teitan Elementary School. During their escapade, they encountered a mysterious figure in the school library who played a prank on them before giving them a code hidden inside a leather wallet. With help from Professor Agasa, Shinichi and Ran managed to partially solve the mystery, marking the beginning of their informal partnership in detective work. It was also around this time that Shinichi began calling her by her first name.

In the same year, Ran met Fusae Campbell, who was waiting for a meeting with Agasa. Fusae gave Ran her umbrella and playfully asked her to buy one of her designer purses when she was older.

A year before Shinichi became Conan Edogawa, Ran traveled with him to New York to visit his parents while her own father, Kogoro, was away on a community trip. It was during this visit that Shinichi solved his first major case, earning recognition as a budding detective. The trip also introduced her to Shinichi’s mother, Yukiko Kudo, and her actress friend Sharon Vineyard.

That evening, Ran encountered Shuichi Akai, who warned her about a serial killer in the area. Later, she crossed paths with Vermouth, disguised as the killer. Despite the danger, Ran bravely caught Vermouth’s arm when she nearly fell to her death, with Shinichi assisting in pulling her to safety. This act of heroism earned Ran and Shinichi the nicknames “Angel” and “Cool Guy” from Vermouth. It was during this trip that Ran finally acknowledged her true feelings for Shinichi, realizing that she was deeply in love with him.

Intellectual Abilities
Ran is a sharp and perceptive individual. While she doesn’t always actively seek out cases like Shinichi, she has demonstrated considerable intelligence and problem-solving skills, successfully solving a few cases on her own.

Physical Abilities
Ran’s most impressive physical ability lies in her martial arts expertise. As a black belt in karate and the captain and ace of her high school team, she possesses exceptional skill and strength, often outclassing her peers in competitions. Her martial prowess has earned her victories in regional tournaments within her age group, showcasing both her discipline and dedication.

Conan Arc
Ran first walks home from school with Shinichi, where she becomes frustrated with his constant talk about his latest achievements and his idol, Sherlock Holmes. She accuses him of overshadowing her father’s work as a private detective, blaming Shinichi for the lack of cases. Shinichi defends himself, pointing out that her father’s ineptitude is the real reason for his lack of clients, which causes Ran to retaliate by intimidating Shinichi with her karate skills.

Ran later reminds Shinichi of a promise he made to her: if she won the Regional Karate Championship, he would accompany her to Tropical Land Amusement Park. During their visit, she becomes an unexpected witness to a murder that takes place on a rollercoaster ride while she and Shinichi are on it.

Bourbon Arc
Conan, Ran, and Kogoro are invited to England by Diana Kingstone, a wealthy and elite British woman, after Kogoro finds her cat hiding under a table at Café Poirot. This marks the beginning of their involvement in a complex mystery in a foreign land.

Black Organization

Vermouth
Vermouth, a high-ranking member of the Black Organization, initially appears to Ran under the alias of Sharon Vineyard, a supposed friend of Shinichi’s mother. Ran later encounters Vermouth disguised as a fugitive on the run from the FBI. When Vermouth finds herself in danger of falling to her death, Ran and Shinichi work together to save her. This act of kindness earns Ran and Shinichi a special place in Vermouth’s heart, with the notorious member of the Black Organization considering them both very precious.

Family Relatives

Kogoro Mouri
Kogoro, Ran’s father, is a private investigator known for his incompetence and tendency to drink. With her mother, Eri, absent, Ran has taken on a maternal role in the household, managing both the finances and day-to-day tasks. Despite the strained relationship between her parents, Ran hopes for their reconciliation and continues to try to bring them back together.

Eri Kisaki
Eri, Ran’s mother, is a successful lawyer. Although she and Kogoro are separated, Ran stays in regular contact with her mother, often discussing the state of their family and the ongoing difficulties in their relationship.

Friends & Acquaintances

Conan Edogawa
Conan, the young boy whom Ran met at Dr. Agasa’s residence, has a sibling-like relationship with her. She looks out for his well-being and safety, often caring for him as if he were her younger brother. Unbeknownst to her, Conan is actually Shinichi in disguise. At times, Ran suspects that Conan might be connected to Shinichi, though she doesn’t fully realize the truth. Conan, in turn, deeply cares for Ran and does everything in his power to protect her from the dangers of the Black Organization, despite the emotional toll of being apart from her. Their interactions, like holding hands and sharing meals, create tender moments that highlight the emotional connection between them.

Shinichi Kudo
Ran and Shinichi share a deep and enduring bond, having been childhood friends since kindergarten. Their relationship is close, and they address each other by first names, with no honorifics. Though Ran is occasionally frustrated by Shinichi’s obsession with Sherlock Holmes and Shinichi is unnerved by Ran’s fearsome karate skills, they have a strong, mutual understanding and get along well.

Ran has romantic feelings for Shinichi but remains unaware that he shares the same feelings for her. When she first meets Conan (not knowing he is Shinichi in disguise), she confesses that, despite his flaws, she is deeply fond of him. This confession causes Conan (Shinichi) to blush, almost revealing his true identity, though he remains resolute in keeping it hidden.

In an effort to explain his absence, Ran believes that Shinichi is away solving difficult cases and won’t return until they are resolved. Since Shinichi’s disappearance, Ran has grown increasingly worried about him, feeling lonely and anxious for his safety. She hopes that he isn’t in danger and yearns for his return, missing him greatly in her everyday life.
