- "I wonder if my station is too much for one of such humble origins."
- ―Yamauchi Kazutoyo.[src]
At only fourteen years of age, Yamauchi Kazutoyo's father died, leaving the young man to wander as a ronin for several years. He eventually came into the service of Oda Nobunaga, and worked his way up to becoming a trusted general. After Nobunaga's death at the hands of fellow Assassin Yamauchi Taka, Kazutoyo served Toyotomi Hideyoshi, who had taken up Nobunaga's goal of unifying all of Japan. When Hideyoshi died in 1598, Kazutoyo served Tokugawa Ieyasu, and played a small but critical role in the latter's rise to power in 1600.
