Jiryu Shiraki

Jiryu is a stoic and serious man, having spent his entire life training to take position as a knight. Being the final blood descendant of the hero Sir Hayward, Jiryu was taken from Japan and inducted into the Order of the Round to fulfill his controversial birthright. Now, he serves as a loyal guard to the world's elite, willing to lay down his life to protect nobility. In the rare case he's allowed to speak, Jiryu is rather excitable and passionate about his Order's oral history.
