This little boy is called Chacha, and his tribe is called the Crocodile Tribe, because there are many enormous crocodiles in the river area around their tribe. These crocodiles are extremely formidable, and the people of the Crocodile Tribe greatly admire the crocodiles' might, which is why they named their tribe the Crocodile Tribe.
The Crocodile Tribe is a great tribe with a population of over seven thousand people, and life is very prosperous. Chacha originally shouldn't face any danger in such a tribe, but although the Crocodile Tribe's life is prosperous, it is not peaceful, and even somewhat dangerous.
It's because the Crocodile Tribe has a neighbor, a cave-dwelling tribe that lives underground, which is very annoying.
They secretly dig tunnels from underground and not only like to steal things but also always steal the Crocodile Tribe's food during harvest time. The most hateful thing is that this cave-dwelling tribe happens to be a cannibal tribe!
