After enduring years of natural disaster and war, the world is left without its main supply of water; the river that provided water to the country dried up long ago. With the greedy king of the land's personal water supply becoming increasingly more expensive for the citizens of Sand Land to buy, the people begin robbing one another for water and money. Sheriff Rao, tired of the king's greed, approaches the demons of Sand Land for help in searching for a new water supply. Demon prince Beelzebub and his friend Thief agree to join Rao.
