Underneath Himeji Castle, Miyamoto Bensuke was determined to inherit the will of his late father, Shinmen Munenori, and aimed to become a great swordsman. For this purpose, he challenged anyone he could to matches and eventually forced a duel upon a martial artist named Arima Kihei, whom he killed. Munenori's old friend, the monk Guan Ando, reprimanded Bensuke's brutality and told him to go to the capital to refine his skills.
