Miles was born to poor parents who abandoned him in the woods after realizing he was Gyee. A she-wolf found and raised him among a wolf pack, before he was forcibly taken to Azria by Markus. There, he received education and joined the Young Azrians. At the beginning, he was reclusive and antisocial, often fighting with peers, until the kind Eddie and gullible Izumi entered his life. With their influence, Miles gradually integrated into the group.
