Kenji Dihara, a former member of the explosive ordnance disposal class of the mobile group of the Metropolitan Police Department, died while defusing a bomb, so he was transferred to the search class. Because my friend was bombed, I vowed to catch the prisoner and take revenge, and I also transferred a class. Three years ago (based on the time when the TV304 shook the police station,120,000 hostage incident occurred), I was bombed and saw the tips given by the same bomber. Before I left, I texted Sato and told him that he liked her. Although there is less than one episode, it is very popular.
