Eiji's life was relatively peaceful when he was younger. He looked up to his father, but had to spend most of his time with his mother because he was always off on missions. He prefered him over her, and so, was usually disobidient when his father was not around. At five, his father taught him of their lineage, how Eiji came from a line of supposedly 'great' ninja and came about with delicate breeding. He instilled in him the thought that he had to become nearly all-powerful, even if it meant defying the laws of the world.
