Tetsu no Michi

Overview

About 1,500 years ago, Achilles, the greatest swordsman of the Roman Empire, heard rumors about the strength of Takeru, a Japanese warrior who had accompanied the Japanese envoys to the Tang Dynasty in China. Achilles decided to take the Silk Road to the east to test his skills. Takeru, on the other hand, is entrusted with the task of escorting the merchants along the Silk Road, and he sets off westward on the arduous journey. The Iron Road is a story of great scale, in which two heroes, one from the east and the other from the west, meet and compete with each other over across thousands of miles.
