Emily O'Hara is a character from the 1990 anime film City Hunter: Million Dollar Conspiracy. A beautiful blonde woman from Los Angeles, she travels to Japan to seek out the services of the private detective and City Hunter, Ryo Saeba. Emily offers a substantial payment of one million dollars to secure his protection, claiming she is being targeted by a dangerous man named Douglas. This initial presentation as a wealthy and vulnerable client in need of a bodyguard is a calculated facade.

Beneath the surface, Emily's true identity is that of an investigator working for the Central Intelligence Agency. Her personal motivation for pursuing Douglas is not merely professional but deeply rooted in a quest for revenge, as he is responsible for the murder of her older brother. This dual nature as both a covert operative and a grieving sibling drives the core of her character's actions throughout the story.

Her role in the narrative is complex, as she serves as the catalyst for the plot while concealing her real agenda. By hiring Ryo, she unknowingly draws him into a larger conspiracy involving a double agent within the CIA and sets the stage for a confrontation with Douglas. Her presence immediately creates tension with Ryo's partner, Kaori Makimura, who grows suspicious that Emily is not what she appears to be and that her true target may be Ryo himself. While the film focuses on the action and intrigue surrounding the conspiracy, there is no detailed information available about Emily's personality traits, her emotional or psychological development over the course of the story, or any notable combat or espionage abilities she may possess.
