Ryu the Primitive Boy - S01

When Ryuu is born, his tribe attempts to sacrifice him to a Tyrannosaurus called Shirano due to the color of his skin. A monkey rescues him and raises him as her own. Meanwhile, Ryuu's mother leaves the tribe to search for him. Sixteen years later, Ryuu meets a girl named Ran, who was sold to his original tribe. The tribe is furious to see him alive and tries to sacrifice him again, this time by burning him. Before they can succeed, Shirano massacres the tribe, killing Ryuu's adoptive mother in the process. Now, Ryuu and Ran set out together to find his mother and her brother, Don.
