In the utopian nation of Ryujinkyo, Kamuna. A boy born with the form of a human and the left hand of a dragon grapples with his identity in a society that both questions and fears his existence. As he begins his training in the ancient art of ryuken, his determination to prove himself fuels a growing rivalry with the fierce demi-dragon Gindu. Meanwhile, tensions simmer beneath the surface as factions outside Ryujinkyo grow restless, seeking to control the divine pulse that sustains the land.
