Path of the Assassin (vol.1-15)

Path of the Assassin, called "Hanzo no Mon" in Japan, is the story of Hattori Hanzo, the fabled master ninja whose duty was to protect Tokugawa Ieyasu. Ieyasu was the shogun who would unite Japan into one great nation. But before he could do that, he had to learn about the facts of life. As the secret caretaker of such an influential future leader, not only does Hanzo use vast and varied ninja talents, but in living closely with Ieyasu, he forms a close friendship with the young shogun.
Brought to you by the masters of manga, Lone Wolf & Cub creators Kazuo Koike and Goseki Kojima, Path of the Assassin bridges the many talents of the two creators: fluid and skillfully drafted fight scenes, social and historical intrigue, and charming characters who expose their personal lives to the reader.
