Hattori Hanzō
As a child, Ishikawa Goemon's entire family was assassinated for political reasons. His mother sent Goemon away for safety minutes before he witnessed her death. Running away with his caretaker, they were attacked by bandits but he was saved by the great Nobunaga Oda. Goemon followed Nobunaga and Hattori Hanzō was assigned to train him in the ways of the shinobi (ninja) along with his martial brother, Saizō.
