Kazuki is a member
of the Kazama ninja clan and the brother of Sogetsu and Hazuki. He wields
the power of flames for his skills. He tends to act before thinking. When
his younger sister Hazuki was kidnapped by Amakusa,
he left his clan in order to save his sister. But in doing so, his clan
ordered his brother Sogetsu to
find and kill the escaped ninja. Both him and Sogetsu eventually met at
Amakusa's castle. There, Kazuki defeated Amakusa and was able to save his
sister. Sogetsu, on the other hand, stayed behind to fight Zankuro.
Since then, he and Hazuki live a life of running from his clan. His father
was killed by Yuga.
