Race Human Age Unknown Tao Attribute Metal Occupation Asaemon Affiliation Yamada Clan Kiyomaru is an unranked Asaemon in the Yamada Clan. After the shogun became impatient of the first team acquiring the Elixir of Life, Kiyomaru and Isuzu were chosen to join Shugen and Jikka to be a part of the second team sent to acquire the elixir. Due to his young age, Kiyomaru is very immature. While departing to Kotaku, Kiyomaru spoke rudely to one of his superiors and childishly did as he pleased, such as cutting one of the ninjas mask to prove his strength and ordered one ninja to kill themselves to prove their loyalty. Kiyomaru is also very arrogant, as he declared that he was far superior to everyone that came along on the mission and hates it when people look down on him for not having a ranking.
