Shoryu is the king of En. Like Youko, Shoryu is a taika from feudal Japan, approximately 500 years ago. He was originally the leader of a clan, and after it was wiped out, he was taken by Enki to rule the kingdom of En. Though En was originally in terrible condition, his 500-year rule has led to an extremely calm and prosperous nation. Shoryu helped Youko by providing her with an army to retake the kingdom of Kei and rescue Keiki. As a fellow taika, Shoryu feels that he should help guide Youko in her new life.
