Jang-Il Jeong was a Sun-Woo Clan elder who became Shi-Woon Yi's teacher after Chun-Woo Han. Although his goal was originally to stop the fight between Shi-Woon and Ji-Gun Yoo by exhausting him through an extreme training regime, he later warmed up to Shi-Woon after he reminded him of the previous clan head with his determination.


He was a tall, middle-aged man with moustache and beard. He had black hair, which was stylised to fall in front of his forehead.


He was an energetic and emotional person. He seemed to lack patience, which resulted in him getting agitated quickly. He is a very proud individual and quite hot-blooded.
