Ba Jio is a commander in the Yo Tan Wa Army and one of the most notable warriors of the Chouga Tribe.
Ba Jio was the only survivor from his tribe after a battle at a very young age. After a few years of living in the wild, he became a beast in human form. This would lead to confrontation with Yo Tan Wa when she was on her way to conquer neighboring tribes. After losing a fight against Yo Tan Wa, she gave him an option of dying as a beast or becoming her companion. This led to him being accepted into her tribe and over time he was able to speak multiple languages and become a powerful warrior.
