Matoku's Origin

Matoku was only 4 when his mother died in a car crash, no-one knows how it happened because no other cars were seen and her car just suddenly dissapeared, so anyway, Matoku went to new york to live with his Father, named Eloe. Matoku's Father told Matoku a story about a great war that happened 3813 years ago, The story ended like this "The Great War had ended as a young, immortal sage had risen as if from nowhere. No parents, No past life, he was just "born" to end the great war. The sage was a knight of the sky and after he used all his powers to stop the war, the powers were sealed for 3809 years and was released into a child..."
