Aoi plays the role of a mysterious and beautiful psychic Kawai Setsuko who will appear in the middle of the season to solve cases with Goro using her supernatural powers. Aoi commented that as she has many lines in the script, she is nervous about playing this character and hopes that she won't cause any trouble to her co-stars and the staff. In addition, as she is only joining the drama from the halfway mark, there are many things she still doesn't know about her character so she's relying on instructions from the director when it comes to her acting. On the other hand, Lily plays Minami, the owner of a publishing company who is actually an information vendor well-versed in matters of the underworld and helps Goro with his cases. He is also a journalist with a dark side and helps resolve problems quietly for big companies and the rich and famous.
