Movie
Description
Rishi Ramanathan is a reserve police officer specializing in criminal psychology, holding a respected position within the Singapore police force due to his expertise. He operates as a student under the guidance of mentor Leon Lowe, focusing on criminal behavior analysis. Physically an adult male with brown hair and dark skin, he is frequently depicted with closed eyes.

His role centers directly on the central case involving the Fist of Blue Sapphire jewel. He approaches private investigator Kogoro Mouri for assistance on the case, leveraging the potential benefits of befriending a reserve police officer to secure Kogoro's cooperation. This approach follows his presentation of Kaitou Kid's notice related to the sapphire heist.

During the film's climax, he actively participates in police operations, armed with a CZ P-07 pistol, the standard sidearm used by the Singapore Police Force and Leon Lowe's security personnel in these events. A figure identified as his father appears within the narrative.
