Jodie Starling serves as an FBI agent, adopting the alias Jodie Saintemillion for her assignment in Japan. Her past is marked by a traumatic event roughly twenty years ago when her parents, fellow FBI agents investigating the Black Organization, were murdered by Vermouth. Discovering the scene as a child, Jodie was instructed by Vermouth to wait by her father's body with the phrase "a secret makes a woman" before Vermouth ignited the house to destroy evidence. Jodie survived only because she had briefly left to buy orange juice for her father. Subsequently placed under FBI protection, she declined the Witness Protection Program and eventually became an FBI agent mentored by James Black. Her father's glasses remain her sole memento from that night. During her FBI career, she entered a romantic relationship with Shuichi Akai, which concluded when he went undercover and became involved with Akemi Miyano. Her personality balances serious professionalism during missions with a playful, carefree demeanor, observed during her tenure as an English teacher at Teitan High School. She maintains composure in crises, exemplified during a bus hijacking where she meticulously preserved her cover identity. She demonstrates open-mindedness by trusting Conan Edogawa's capabilities despite his apparent youth. However, she harbors a profound grudge against Vermouth, reacting negatively to any hint of Vermouth's potential kindness. Highly observant and skilled at deduction, though not matching Shinichi Kudo or Akai, her emotional vulnerability surfaces concerning Akai, causing her to weep upon initially receiving false news of his death; she retains deep care for him despite their current professional dynamic. Her abilities include proficient marksmanship, demonstrated when she outdrew Vermouth in a confrontation and intervened in operations involving Kir and Rikumichi Kusuda. Her deductive skills allowed her to nearly reconstruct Akai's fake death ruse independently and uncover Vermouth's dual identity as Sharon and Chris Vineyard. Fluent in English and functional in Japanese, she initially learned the language from a friend, resulting in occasional grammatical errors. She utilized these language skills in her teaching role at Teitan High School. Her case involvement begins with the Arcade Murder Case, where she assisted Conan in solving the crime while monitoring him as a "rotten apple." During the Bus Hijacking Case, she helped Conan thwart the hijackers, using Vermouth's phrase "a secret makes a woman" and shifting her address for Conan from "Cool Guy" to "Cool Kid." In the English Teacher vs. Great Western Detective case, Heiji Hattori suspected her of Black Organization ties, though she was cleared. Her FBI identity was later revealed to Conan during the Clash of Red and Black arc, where she participated in protecting Rena Mizunashi and deduced a Black Organization member's presence at Haido Central Hospital. She also encouraged Ai Haibara to join the Witness Protection Program, respecting Haibara's refusal by acknowledging a courage she lacked as a child. In *The Scarlet Bullet*, she participates in the investigation of kidnappings linked to the World Sports Games (WSG) in Tokyo, noting parallels to a similar incident in Boston 15 years prior under FBI jurisdiction. She operates under Shuichi Akai's directives with the FBI team. During the climax aboard the Hyper Linear train, she executes Conan's strategy by calling all passengers' phones to expose the culprit, Maiko Shirahato, whose damaged phone failed to ring. This action directly contributes to Shirahato's identification and subsequent neutralization by Akai.
