Relatives: Kogoro Mouri (husband), Ran Mouri (daughter), Mr. Kisaki (father)
Occupation: Lawyer

Her real name is Eri Mouri. She began to use her maiden name again after she began living separately from her husband Kogoro Mouri. She also runs her law practice under her maiden name. In a recent hospitalization, her name was displayed as "Eri Mouri" on the door. She has one daughter, Ran Mouri. Eri has advanced skills in Judo, taught to her by Kogoro.

The separately-living wife of Kogoro Mouri, Eri is a lawyer who often gets tangled in Kogoro's cases, usually serving as an extra pair of eyes when it becomes time to investigate a crime. Although she does not like Kogoro's attitude and personality _(especially his drinking and skirt-chasing habits),_ she still deeply loves and cares for him, often testing him to see if he still cares about her as well.

Her personality suits her occupation as a lawyer. She is often very questioning, and gets herself involved in the investigation of cases along with Kogoro, much to his chagrin. She has a cat, a Russian Blue named "Goro," whom she cares for very deeply; in fact, Goro's name comes from "KoGORO" of Kogoro Mouri, since to her the cat and Kogoro both act very similar in some ways. Eri is also very close friends with her secretary, Midori Kuriyama.
