Mouri Ran is a childhood friend of Kudou Shinichi. She is the daughter of Mouri Kogorou, a private detective, and Kisaki Eri, a lawyer. Her parents got separated when she was seven, and one of her biggest goals is to get them back together. Her best friend next to Shinichi is her classmate Suzuki Sonoko, who constantly teases her about her relationship with Shinichi. After Shinichi's disappearance, Ran met Edogawa Conan, who was introduced by Professor Agasa as a "distant relative" and asked Ran if she wouldn't mind taking care of him at her house. She and her father practically adopted him; Ran immediately came to think of him as a surrogate little brother. Little did (and still does) Ran know that "Conan" is actually Shinichi. Ran's greatest personality trait is that she genuinely cares for those she loves. She is also patient, kind, and nurturing. Like Shinichi, she highly values justice to the point of idealism. To avoid making Shinichi choose between her and his important case (really an excuse because Shinichi has turned into Conan and can't return), she has decided to wait for him to finish it, trusting his promise that he will come back despite their separation causing Ran a lot of emotional pain. Ran is also very hot-blooded and tends to act on impulses when the people she cares about are involved; the combination of jumping to conclusions and not hesitating to use karate on those who she perceives to have wronged someone have led to several "near-miss" misunderstandings. Early on, she would become violently suspicious if she thought Shinichi was philandering although more recently his confessions have lead her to trust his intentions. Even though Ran is in love with Shinichi, she often fails to convey her feelings because she suddenly becomes self conscious. She can be very brave and resourceful when she wants to be, and rescues Conan from trouble on occasion. However, she has an irrational fear of the supernatural and is thus - unlike her friend Sonoko - absolutely no fan of anything related to the horror genre. She also constantly tries to reunite her father and mother again - though with little success, thanks to the mutual stubbornness of both parents. Men also tend to pay her a lot of undue romantic attention, a fact that makes Sonoko somewhat jealous (and of which Ran herself is completely unaware). Ran is very self sufficient for her age. This is because her father is drunk, slovenly, and fiscally irresponsible. She handles many of the Mouri household's financial affairs and all the cooking and housework. She also ensures Kogorou doesn't slack off on his job, is on his best behavior for client meetings, and she often greets and provides refreshments for potential clients.

Birthday: June 18 Blood type: AB Ana is an eleven-year-old girl who originally came from Cornwall, England, five years before the series, but seems to have forgotten how to speak English. She first pretends that she speaks only English, but it is not long before she is discovered by Matsuri while speaking very polite Japanese. Matsuri tries to help her re-learn English. Ana is often teased by Miu because of her name, Ana Coppola, which can be written in kanji to mean "hole", "bone", and "cave" (穴骨洞, "hole", "bone", and "cave"?). Miu nicknamed her "Coppola-chan", much to her grief. Ana's "proper Japanese" personality is reflected by her very traditionally feminine and polite speaking style.
Birthday: October 17 Blood type: A Nobue is the eldest main character. She is Chika's older sister and usually has final authority on all matters. She often tries to "borrow" money from Chika to buy cigarettes. Nobue is perpetually searching for a part-time job to earn money for more cigarettes to calm her nicotine addiction. The story suggests that Nobue derives some kind of sensual pleasure from watching the girls do cute things. In this respect, Nobue appears to appreciate the moe aesthetic. It is seen during the anime that Nobue prefers Matsuri and Ana over Chika and Miu. The Nobue character changed from the manga to the anime. In the manga, she is a sixteen-year-old high school freshman, while in the anime she is a twenty-year-old junior-college student. Her age is presumably changed because of her smoking and drinking habit, both becoming legal in Japan at age twenty. Although in the first episode of the anime she introduces herself as a sixteen-year-old, this was intended to be a joke as she quickly stated that she was twenty. She tends to act somewhat less mature in her manga incarnation, doing things such as tricking Matsuri into thinking that Miu is dead. Her appearance changes radically in the early stages of the manga, especially her hair, which goes from blond to dark brown (and is black in the anime).
Birthday: September 8 Blood type: B Miu is another twelve-year-old girl who is depicted in the story as having a problem-child personality. A childhood friend of Chika, she lives next door to the Ito house and attends the same class as Chika. Miu likes to say random things out of the blue and often plays pranks on Matsuri and Ana, but is most of the time interrupted by Nobue (and sometimes by Chika), ending up lying face-down on the floor. She has the least common sense or manners of the girls, and is rarely taken seriously because of her weird ideas and comments. She seems to harbor some sort of jealousy of Ana and Matsuri, because Nobue finds them cuter. Miu is nicknamed "Micchan".
Saturn appears in Seto no Hanayome OVA as an old friend of Seto San who pays a visit to the school.
Hideyoshi Sarutobi, often referred to as Saru, is a friend of Nagasumi who is often portrayed as a perverted monkey (a pun on his name; "saru" meaning monkey). He later became Kai's "servant" and always protects and helps him when he is in need (although reasons are more likely because of his fortune). Saru occasionally appears dressed as an old hermit, "ero-sennin" (erotic/perverted thousand-year-old), who periodically appears to offer insights of perverted sagacity. (Source: Wikipedia)
