Ba Tei's father was a friend of Ki Shou. He died when Ba Tei was still a child and after that he was adopted by Ki Shou. During the conflict between Rigan and Anka, he would fight side by side with Ki Sui and Ryuu Tou and turn the tides of war.
Alongside Ki Sui, Ryuu Tou, and Kei Sha, defends Koku You from Kan Ki Army. Defeated when Kan Ki's psychological warfare took a toll and the deaths of Kei Sha and Ryuu Tou took their wills out.
While Ba Tei's use of tactics is not bad by any measure, his true forte lies in his overwhelming strength, making him of key attackers in Ki Sui Army. He was able to ambush and overwhelm Shin during their first meeting. Later, he fought powerful commander Shi Ryou to a standstill.
