Chosuke Takagi is a police detective and Megure's senior by two years. He was moved from Tokyo to Tottori in order to help with the investigation of a large crime syndicate there.
Chosuke was shown to be very aggressive at times in an investigation. Once he grabbed Chiba by the collar and slammed him against the wall just to ask him for confirmation to a question. He is also very efficient at investigating, taking notice of minor details and connecting the dots rather quickly. He suspected Chiba of lying to protect his friend in the first case he appeared in, because he believed that as a police detective he had to suspect everyone no matter how good they are.
Chosuke first appeared in one of the Police Detective love cases, in which the other Tokyo police thought Wataru Takagi was being sent to Tottori. Chosuke investigated a crime with Sato and Takagi that involved a friend of Chiba's. After the case was solved, Takagi found out that it was Chosuke being sent to Tottori and not him.
- Altough he and Takagi share the same surname, they are not from the same family but it caused some misunderstanding.
