A member of Creed's "Apostles of the Stars", Kyoko is a hyperactive high-school student. Often partnered up with Charden, she tends to be more of a messenger than a fighter. In battle however, she can use Tao to raise her body temperature to ridiculous degrees, which she can then expel as fire. Like other Apostles, she believes what Creed is doing is right, though it's mostly in a "yeah, whatever" childish way. She falls in love with Train shortly after their meeting, and continues to idolize him throughout the series.
