- In the fifth month of Keio 4 (1868), on the brink of the new Meiji era, Usui Watari, the administrator of the small domain of Akizuki in Kyushu, and his wife, were assassinated. Blazing anger grew in their son, Rokuro (Fujiwara Tatsuya), who had witnessed their tragic deaths. However, the period dealt a cruel date to Rokuro. Vengeance, once a samurai's virtue since the Kamakura era 700 years ago, has now transformed into murder - a crime that should be hated - with the passage into the Meiji era. Then in 1870, Rokuro created a great debate when he finally carried out his revenge. Should he be praised as the "model of a filial samurai"? Or should he be judged a mere "murderer"? Furthermore, the enemy he had attacked was a person who had a job as a judge.
