Midori Kuriyama serves as paralegal and secretary to attorney Eri Kisaki at the Kisaki law firm, joining shortly after its establishment following Eri’s separation from Kogoro Mouri. She oversees administrative duties—managing calls, scheduling appointments, and streamlining office operations—often arriving early to ensure preparedness. Her background includes law studies at a Tokyo university, which informs her meticulous approach to legal support.

Known for her cheerful and approachable demeanor, Midori engages in playful teasing of Eri, particularly regarding Eri’s interactions with Kogoro. She actively bridges their communication, such as advising Kogoro on gifts for Eri during the Swapped Bags Case despite her own illness. This event underscores her recurring role in facilitating their relationship.

Midori appears in both canon and non-canon narratives. In manga chapters Files 413 and 984-986, she assists Eri in resolving Kogoro’s debt and faces temporary incapacitation during Eri’s kidnapping. Non-canon films feature her discovering poisoned chocolates in *The Fourteenth Target* and aiding Conan in locating Eri in *Captured in Her Eyes*. The spin-off *Zero’s Tea Time* positions her as a Café Poirot regular, interacting warmly with staff like Azusa Enomoto and integrating into the series’ broader social fabric.

Physically, Midori is tall and fair-skinned, with long dark brown hair and professional attire. Early non-canon portrayals inconsistently depicted her with reddish or brown hair and grey or green eyes.

Her professional rapport with Eri balances mutual respect and informal camaraderie, blending personal conversations with work. Interactions with characters like Conan Edogawa and Rei Furuya (Tooru Amuro) remain courteous and task-oriented, reflecting her role as a steadfast narrative anchor.
