Yuichi Sawajima traveling through time and space is a journalist from the future company Time Scoop Corporation. His mission is to document the lives of people from the past – people who never appear in history books. In this episode, Sawajima warps back to 1608, the time of the early Tokugawa Shoguns at the beginning of the Edo period. His assignment: to document the Red-Hot Iron Oath. During Japan’s feudal era, a painful brand of justice was sometimes meted out to settle disputes. In theory, the champions of each side of a dispute would be required to hold a red-hot iron bar: the one who suffered the lighter injuries was judged the winner. The result was considered to be the will of the gods.
