Actually, the Brave Tribe wasn't always this cruel. They were very united and harmonious, and they treated the weak with great care and affection.
That is, until the appearance of the current chieftain, who ultimately shattered the peace of the Brave Tribe.
He viciously murdered the previous chieftain, who was Yangjima's father. Anyone who disobeyed him was suppressed with bloody measures.
At that time, Yangjima was only six years old. She witnessed her own father being killed by this man right before her eyes. How could she possibly not harbor hatred?
Now, the Giant had ruled over the Brave Tribe for a full ten years. In those ten years, the Giant had changed the lifestyle habits of the Brave Tribe, making it a place where strength was admired. The strong could live better and do as they pleased, whereas the weak were subjected to bullying and even used as food in seasons of scarcity, especially those women who lacked the ability to work.
