Kuriyu Kohei (Takuya Kimura), a bad boy who dropped out of junior high school, passed the examination of the Ministry of Justice by mistake and became a qualified prosecutor. He often wears jeans and leather clothes, and does not follow the rules and regulations to work alone. He was transferred to the Criminal Department of the Tokyo District Prosecutors Office's Josai Branch and began his work as a prosecutor. Here, he met Officer Amamiya Maiko (Takako Matsu). Amamiya Maiko has always hoped that she can become a deputy prosecutor one day, so she usually obeys her boss. Originally, she was happy to hear that an excellent prosecutor would be transferred to her department, but when she saw Kuriyu, who was unkempt, especially his unprecedented way of handling cases, Maiko was shocked and had many conflicts with him in addition to disappointment. In fact, Kuriyu Kohei just handled the case seriously according to his own ideas, and he solved many cases in his own way. This also won the recognition of colleagues and the love of Amamiya Maiko.
