“Book Descriptions: With only three ninja remaining on each side, the battle between the Iga and the Kouga clans is nearing its bloody end. Believing he has slain Yakushiji Tenzen, shape-shifter Saemon Kisaragi morphs into Tenzen’s body and infiltrates Iga territory. But what Saemon doesn’t know is that Tnezen is an immortal ninja, and that he has his own plan to dispose of Saemon and the Kouga clan.” DRIVE
