With the defeat of Saito and Takeo, peace was restored in Tosa, but the bond between Hiro and Saito was forever broken. Saito was furious that Hiro had exposed his treachery and had brought him to justice, and he felt that Hiro had betrayed him a second time. He couldn't forgive Hiro for his actions and decided that the only way to regain his honor was to defeat Hiro in a duel.

Saito challenged Hiro to a duel, a one-on-one battle to the death. Hiro knew that he couldn't refuse the challenge, as it was his duty as a samurai to accept. He accepted the challenge, knowing that it would be a difficult and dangerous fight.

The day of the duel arrived, and the two former friends met on the battlefield. They bowed to each other, and the duel began.

The fight was intense and brutal, both warriors fought with all their strength and skill, but neither could gain the upper hand. They fought with their swords, their fists, and even with their bare hands. They fought for hours, until they were both exhausted and wounded.

In the end, Hiro emerged victorious, he had defeated Saito, but he had not killed him. He knew that Saito was still a skilled warrior, and he had no desire to take his life.

Saito, however, saw things differently, He was ashamed of his defeat and saw it as a dishonor, and he couldn't accept living with such shame. He took his own life, as a way to restore his honor.

Hiro was saddened by Saito's death, but he knew that it was a necessary sacrifice, to protect Lord Nakamura and Tosa. He knew that Saito was a victim of his own ambition and pride, and that he couldn't have changed his fate.

He fulfilled his duty as a samurai, and he had protected his lord and the people of Tosa. But the victory came at a great cost, he had lost his friend and brother-in-arms. He rode off into the horizon, with a heavy heart, ready for his next adventure, but also, with the memory of Saito, forever in his mind.
