The Yellow Dragon Officer, Ruwalk acts as the Dragon Lord whenever Lykouleon cannot. He is childish and mischievous, but fights hard to protect the Dragon Tribe. Ruwalk has a tendency to give extra money to Kaistern for his frequent trips and help Lord Lykouleon slip out of the castle unnoticed. Always one to stand up for those trying to slide around the various castle formalities, he tends to get in trouble with Alfeegi quite often. He is Lykouleon's childhood friend and most of the time calls him by his given name without the title of "Lord": Ruwalk is Lykouleon's closest confidant and one of the few who are close enough to him to give him blunt advice or help. Ruwalk was also the one who chose to keep "Illuser" ["Eryusa" in Japanese] as Rath's last name.
