Kyle is a young man with aqua colored hair and green eyes. He wears his hair in a ponytail and wears a uniform of the Capua Sky Bandits.
Kyle is shown in The Trails in The Sky trilogy as a relaxed, yet intelligent figure. Though he can get easily flustered at remarks from his siblings, Don and Josette, no matter what they throw at him.
Kyle Capua was of Erebonian nobility when he was younger. However, due to the debt his family had after being conned by a fraud merchant, he and his siblings had been wiped from noble status and had everything taken away. After being thrown out from their normal lives, Kyle and his siblings resorted to becoming sky bandits in Liberl. The Capua family then meet Estelle Bright, Joshua Bright, and Scherazard Harvey in one of their first big missions. He is very devoted to his family.
Kyle specializes in bombs and tactics for the Capua family. Just like his siblings, he is very fond of the family airship, the Yamaneko.
After being pardoned from their crimes for assisting in the society, Kyle and his siblings created a merchant business with their airship. The Capua Express can be seen in The Legend of Heroes: The Trails of Cold Steel III with his sister Josette appearing.
