Sanpuu Minami is a popular shojo manga artist who is believed by many to be a woman. In actuality, though, his real identity is Eichizen Gotaro, a single father with two children. One day, he receives a notification from the court that he has been appointed as a prosecutor’s office examiner. With the deadline for his manga approaching, he requests a withdrawal but this is declined due to a lack of special circumstances. He joins 11 other people randomly selected from ordinary Japanese citizens, who each have unique personalities and give off the impression that they would like to get this over and done with. At first, Gotaro has a negative attitude towards the Prosecution Review Board, but as he gets closer to the thoughts of those behind the case, he starts to appreciate how important this job is.
