Richard, son of Sariphi and Leonhart, belongs to both the human nation of Yoana and the beast kingdom of Ozmargo. With an important coming-of-age ceremony approaching, the young prince leaves home on a journey meant to prepare him physically and spiritually for the responsibilities ahead. Traveling beyond the palace exposes Richard to people who judge the royal family very differently, forcing him to understand the two worlds he is expected to inherit for himself.
