Her credo is “science never lies” and she delves into the truth of the case with her colleagues with their specialized skills and knowledge in forensic medicine, physics, chemistry etc. Mariko’s steadfast belief in science makes her stand against conventional institutional ethics of the police department, diehard detectives averse to scientific investigation and sometimes even with her own colleagues, but she stays faithful to her belief in science and continues to pursue the truth.

Takamura Naho is the deputy curator of Ariyoshi Art Museum which has a large collection of art. She took over from her grandfather Ariyoshi Kisaburo who is an avid art collector and founded this private museum. She also inherited his eye for beauty. Naho’s husband Kazuki is similarly involved in the world of art as the third-generation owner of an art gallery in Ginza. Even though Kazuki loves his wife, he is also jealous of her talent at times.

One day, Naho comes across a painting of new green leaves by an obscure artist called Shirane Tatsuru when she stops by Minoyama Shungo’s art gallery and finds herself strongly attracted to it.
