The Hamato Clan were responsible for the temporary extinction of the Foot Clan, the oldest of all ninja clans. In their final attack to the Foot, Hamato Yūta killed Oroku Kaiji, the leader of the Foot Clan, and took his son, Oroku Saki, as a baby and raised him as his own. Yūta also had a son of his own blood, Hamato Yoshi, Saki and Yoshi grew together, competing in all matters as brothers do, even in love. 15 years later Saki found out Yoshi was still alive and followed him to end what they started.
