Ken Shidou is the brother of Mika, younger than her by three years, and the last member of the Flame Tribe to be awakened. His powers appeared when the Wind Tribe attacked the activated Garuda with Dolcross. He is the calm and collected one, a shy but caring and compassionate person who deeply loves his sister. After meeting Ran, he developed a crush on her, but he would never admit it. With his Knuckle Riser, Ken transforms into Sazer, the flame warrior under the sign of Leo. His black and red armor is shaped after a Swallow. The finishing attack of his Double Crescent swords is called "Hien Zan" (Flying Swallow Cut).
