Relationship analysis

Kogoro and Eri in school

Kogoro Mouri and Eri Kisaki (officially Eri Mouri) have been a married couple for about 18 years, with the last ten spent separately because of huge personality clashes. Before the marriage, they were very good friends and a couple since elementary school. Despite being separated, they still love and care about each other, although they often put on a show of disdain for each other. It is a running gag that over the course of a case, one of the pair will come close to asking the other if they could move back in together, but then somehow Kogoro ruins the situation by doing something inappropriate or drunkenly flirting with another woman. Their daughter, Ran, is constantly trying to get them to hook up with each other; usually, it is by directly asking them or by planning out ways for them to see each other out of the blue.

Kogoro and Eri moments

Manga/Anime

Volume 11: Files 105-107 / Episode 32: Coffee Shop Murder Case

• Eri is revealed to be Ran's mother right before the end of the case (Conan does not recognize her because he have not seen her in ten years).
• When Ran asks whether she is considering going back home, Eri firmly rejects, and proceeds to list the many vices of Kogoro, and also claims that the only invaluable things that have come out of the marriage are Ran and the one-arm shoulder throw manoeuvre that Kogoro taught her.
• Ran does not give up, and asks why Eri married Kogoro if she knew that he had so may flaws in his personality; Eri replies that maybe it is just the destiny of childhood best friends.
• Ran also asks why Eri would not take off her wedding ring if in fact she thinks so poorly of Kogoro. This question turns out to be too easy for Eri; she casually replies that the ring serves to tell other "boring men" that they should not try to flirt with her.
• Although Eri cannot find anything positive to say about Kogoro, she still have feelings towards her, as evidenced by her proud expression when she sees Kogoro on TV (Kogoro, via Conan, is revealing the truth behind a previous murder case).
• The clip played on TV also includes a phone call where Kogoro tells some woman that since he and his wife no longer live together, he is available for an all-night celebration. This visibly annoys Eri, and she waves goodbye to Ran as she says that she will not go back home just yet.

Volume 14: Files 131-138 / Episode 96: The Cornered Famous Detective! Two Big Murder Cases

• Ran encourages Eri to call Kogoro; she does exactly that, and tries to introduce a new client to Kogoro, only to be yelled at by an indignant Kogoro, who says that he does not need her help. Kogoro then orders her to stop bothering him before hanging up angrily.

• This is the first occasion where Ran tries to fix her parents' relationship by telling them to go somewhere separately and making them meet, pretending that it is a coincidence and that they meet because there is a telepathic connection or something like that between them.
• Eri accidentally loses her wedding ring on the beach, but pretends that she has deliberately left it at home in order to see if Kogoro has noticed.
• As Kogoro appears to not have noticed anything, Eri sighs and remarks that her marriage is a failure, and that maybe she should end it altogether and start a new stage in her life.
• The fact that Kogoro brings over a few young ladies to Eri later (and invites them to have lunch with them) makes Eri's thoughts firmer. As Kogoro introduces Eri to those ladies, she interjects and claims that she is his ex-wife.
• After the case is solved, Kogoro tosses Eri's missing ring to her, and tells her that he knows since the beginning that the ring was missing, and thus set out to find it. This implies that Kogoro actually met those young ladies accidentally, and did not meet them on the beach, flirted with them and invited them to have lunch with them.

• Later, Kogoro is found in a locked room, with the corpse of the female lawyer that he flirted with a moment before; Kogoro is sleeping at the time Eri and others break into the room and sees the corpse.
• Much to everyone's surprise, Eri refuses to defend her husband in court, while openly declaring that in her opinion, the evidence strongly suggests that Kogoro has murdered that lawyer.

• When she arrives at the Detective Agency, she finds Kogoro muttering Yoko Okino's name instead. Ran swears that Kogoro was saying her name before, and Eri accepts this explanation, albeit reluctantly. She then says that she agrees to help only because she does not want Ran to have a father deep in debt.
• Eri meets Yukiko Kudo after not seeing her for ten years; both are excited to see each other. They bring up the "Miss Teitan" competition, which was held 20 years ago to decide who was the prettier and more talented between Eri and Yukiko.
• After Eri gets 10 million yen of commission fee, she pays off Kogoro's debt and head back to the Detective Agency, planning to leave the rest of the money to Kogoro and to ask him about whom he voted for in the competition.
• Kogoro reveals that if he had not thought that the competition was too boring, he would have voted for Eri, because he thought that the word "miss" in "Miss Teitan" was the verb referring to "fail to do something".
• Ran asks how he would have voted if he had understood the true purpose of the competition, and Kogoro says without hesitation or reservation that he would have voted for Yukiko instead of Eri.

• Ran is still not entirely convinced, and remarks that Eri is showing way too much of her body.
