Takayuki Yagami is a former lawyer struck off the bar following a case that resulted in the release of a man responsible for the murder of his girlfriend and a fire. Yagami became a private investigator in his hometown of Kamurocho. With the help of Kaito, a former yakuza who now works for him as as an investigator, Yagami will have to investigate a case of murders and enucleations of yakuza by a serial killer.
This mysterious case seems to have a link with his past as a lawyer and more particularly with the case which led to his deregistration three years earlier. As a private investigator, Yagami will have to pick up suspects in pursuit and in case of flight, pursue them and avoid obstacles. He will also have to fight.
