Nina

Nina is a professional intelligence and law-enforcement operative who remains focused while facing an immediate threat. Her brief appearance gives little opportunity for extensive characterization, but she understands that the information surrounding the Europol breach is dangerous.

Her friendship with Jodie Starling establishes a personal connection between the European incident and the FBI personnel later discussing the Black Organization's actions.

Nina is a Europol operative familiar with the agency's security environment and the threat posed by unauthorized access to its systems.

She attempts to escape pursuit once the Black Organization moves against her, demonstrating awareness of the danger and the urgency of preventing compromised information from spreading.

The film does not establish specialized combat techniques or unusual physical abilities for Nina. Her professional significance lies in her work with Europol and her knowledge of the security breach.

Nina appears in Frankfurt during the opening of Black Iron Submarine. The Black Organization has penetrated Europol's network, and she is caught in the resulting operation.

Kir and Gin pursue her as she attempts to escape. The incident is later reported to Conan Edogawa through information connected to the FBI.

Kir attempts to spare Nina rather than execute her herself. Gin recognizes the hesitation and fires through Kir's shoulder, killing Nina with the same shot.

Nina's death helps establish that the Black Organization has breached Europol's systems and that a new operative, Pinga, is connected to the cyberattack. The incident becomes one of the warnings leading into the larger assault on Pacific Buoy.
