Hanzo is one of Ieyasu's trusted warlords. He is the most famous ninja in the history. When Nobunaga was assasssinated by Mitsuhide in 1582, Ieyasu was at Kyoto with only a few guardsmen. That was the greatest danger in his life, because the death of Nobunaga would surely cause major civil disorders elsewhere. Hanzo collected precise information and made a plan to escape from Kyoto through Iga to Ieyasu's home castle in Mikawa . He also persuaded ninja in Iga county, and succeeded to made them follow Ieyasu . After that, Hanzo commanded the Iga ninja army for espionage operations. Unfortunately, his operations were so stealthy that very few are known today. But Ieyasu highly trusted him. He died from illness in 1598, five years before his master became shogun.
