Iruma Michio is a devil-may-care, unorthodox criminal judge at the Tokyo District Court's first criminal court. He used to be a lawyer and was deeply involved in a past case that was behind his transformation into a judge. Iruma personally inspects crime scenes to prevent a miscarriage of justice and bring the truth to light. Although his demeanour is far from the image of a stuff judge, he is feared by lawyers as well as prosecutors because he is not bound by obligations, prejudices and preconceptions and has an inquiring mind that probes cases thoroughly. On the other hand, the judge Sakama Chizuru is the complete opposite of Iruma. A graduate of Tokyo University's Faculty of Law, she is an elite among elites. She has been transferred to the first criminal court to reform it due to the unbelievably small number of cases that are closed. This is the equivalent of a company in the red to the extent of going bankrupt. As someone who takes great pride in maintaining public order by handling cases accurately and promptly, Chizuru cannot understand Iruma's style which frustrates her to no end. However, when she realises that Iruma believes in treating a case as an individual's life, she is faced with the question, What can a judge do aside from issuing a ruling?
