A place called Paradise. It is the origin of civilization and faith. It is a peaceful garden where humans and monstrous creatures have coexisted in peaceful harmony throughout all time. Suddenly, the monsters become violent and begin to attack the humans.
This vicious change is the result of an experiment to revive the great monster, Gyumao (Bull Satan). Bull Satan has been confined for five hundred years. By mixing science and sorcery, someone started the forbidden experiment that brings this monster back to this world. Bull Satan´s revival is imminent. His negative power begins to spread throughout Paradise. The monsters and beasts become wild and the entire world suffers pending disaster.
The resurrection of Gyumao/Bull Satan must be stopped. An apostle of the Celestial Heavens, Sanzo, is summoned to take on the mission of restoring peace and order in Paradise. Sanzo recruits his old comrades, Son Goku, Sha Gojyo Jo and Cho Hackai. The foursome has shared much joy and sorrow and together they have faced many challenging missions. Thus, the outrageous young warriors set out for a journey toward "Indara", a country in the distant west where Bull Satan is close to re-awakening..
