Japan, Hokkaido.
It was drizzling under the gloomy sky. At this time, in a prison in a small town on the northeast part of the island, a man slowly walked out of the darkness. With the congratulations of the prison guards, the iron bars of the prison were opened, and he was sent out of the prison.
The moment he walked out of the prison, the man hesitated for a moment, but in the end, he still walked out.
There was no one outside to welcome him, nor did anyone come to congratulate him. There was only the cold rain patting on his body.
He was released from prison?
He could not help but look at his empty right arm and laughed at himself.
He slowly raised his head to look at the sky. The fine raindrops fell on his face, and he could not help but close his eyes.
At this moment, his memory returned to ten years ago.
……
His name was Hokushin Itto, and he was the direct descendant of the ancient Japan sword style, the one blade school.
