Kiryu

Kiryu (機龍, Kiryuu lit. Metal Dragon) is a Dragon who had used Compact Regression to become a Human years after the war ended, and is, as his name implies, an Iron Dragon. He is the one who raised Lamia since she was a child as his own granddaughter, but never taught her any Dragon Slayer Magic due to keeping his true identity as a Dragon a secret.

Trivia

 * Kiryu's appearance is based off of Maira from MÄR.
 * Kiryu is named after a Godzilla character of the same name, whose name can mean both "Machine Dragon" and "Metal Dragon".
