1x40 - Saiyuki

500 years ago. In the Celestial Heavens. Born from a stone, Goku was brought to Goddess of Mercy – Kanzeon Bosatsu. He was introduced to his guardian – Konzen Doji who is a handsome young man with beautiful blond hair. (Konzen is the previous existence of Sanzo.) He takes care of Goku just like his younger brother. Then, Goku meets a boy called Nataku. Even a small boy at Goku's age, Nataku is the Lord of War and is the only person in the Celestial Heavens, who is allowed to kill. He receives an order to subjugate the great monster, Bull Satan – Gyumao.
