For many centuries, people were forced to work in harsh conditions and work nonstop for the leader of the clan. Yamamuro Kiemon, a man who killed thousands and burned down cities with his clan, if people did not listen to him, they would be brutally punished. A group of rebels was made to fight back his forces and to save the city from his rule. Hiroto Keizo was the leader of the clan and led many battles that caused casualties to the group and clan. Hiroto meets a woman called Sada Miyako and he falls in love with her. They have a child and name him Seto Keizo. Hiroto continues to fight battles and wins each one which soon pisses off the leader. He sends troops to their base to ercadite whole group. Hiroto hears gunfire from upstairs and sees the leader with his group. Telling his wife to take the secret passage and to head as far away as you can, she takes her baby and leaves. Hiroto does the best he can to deal with them but soon she is overwhelmed and falls to the ground being shot in the head and dies..
