The Kikuta Master was Kikuta Kotaro, followed by his nephew Kikuta Akio. They are very traditional in their thinking and do not want to let peace succeed throughout the three countries. Takeo's father Kikuta Isamu was the greatest assassin in the Kikuta before he met Takeo's mother and defected to The Hidden. He was killed later by Kikuta Kotaro when he had refused to fight him because of the Hidden's religion and the vow he made to never kill again after he married Takeo's mother.
