The Earth has been ravaged by war in the distant future, resulting in a desolate expanse controlled by a covetous monarch who monopolizes the supply of water. In pursuit of a vanished lake, Sheriff Rao enlists the aid of the ruler of the demons, and is presented with assistance from Beelzebub, the king's offspring, and the larcenous Thief. In a collaboration that appears improbable, the trio embarks on a treacherous journey across the arid terrain, contending with dragons, marauders, and the most dangerous adversary of all... the King's troops themselves! This latest tale, authored by Akira Toriyama, the originator of Dragon Ball Z, combines elements of travel and tank warfare.
