The First Samurai (Unabridged‪)‬

The Time Warden Returns! 

In the distant future, the Ministry of Chronological Investigations directors realized someone had tampered with the natural order: the Samurai never emerged. Bushido, the soul of the Japanese people, no longer guided their actions. 

To repair the damage, the Ministry trained a Geisha, blacksmith, tanner, tinkerer, and vagabond mercenary and sent them to return to ancient Japan and save Sōma no Kojirō, the first Samurai. 

A mission intended to last one week has failed, leaving the travelers stuck in time. Somehow, Noboru must reassemble his team and restore the Way of the Warrior, or mankind will never escape the dark ages.
