Shadow Warrior of Nobunaga Oda.

In Tensho 9, as Oda Nobunaga nears the unification of Japan, he assigns trusted generals to conquer remaining regions. Meanwhile, a peasant farmer named Sahei, resembling Nobunaga, is chosen by Hideyoshi and Sen no Rikyu to act as Nobunaga’s shadow. Furious at the idea of a double, Nobunaga confronts Sahei, who courageously performs the "Atsumori" dance, impressing Nobunaga enough to accept him as his Kagemusha. Sahei’s first test as the shadow warrior comes at a memorial service for the Oda family.
