Fan Casting Ryu the Primitive Boy

Set in primitive times, a baby with white skin named Ryu is born into the world. But since his skin colour is different from the rest of his tribe, the baby was considered a devil by the tribe as he was left by them to be sacrificed to Tyranno the dreaded one-eyed Tyrannosaurus Rex. However, the baby is saved by an ape called Kitty who raises him as her own son. Meanwhile, Ryu's mother leaves the tribe to find Ryu. 16 years later, Ryu grows up to be a good man, but when the tribe learns Ryu is still alive they try to burn him at stake. Before the deed was done the tribe was attacked and massacred, along with Kitty, by Tyranno. Longing to reunite with his mother, Ryu sets out on a quest to find her. Along the way, he meets Ran, a girl who was sold to Ryu's tribe, Don, Ran's long-lost little brother, and Kiba, a man who wants to kill Tyranno for wiping out his family and tribe. With his newfound companions, Ryu will journey through and struggle to survive the savage world they live in as they encounter various hardships, life-threatening obstacles, and dangerous creatures to find Ryu's mother.
