Gu Wen Jing (古文靜) is a Chinese teacher at Ba Le High School. She is often seen hanging out with Jia Yong, whom she has a major crush on, and the drillmaster. Together, they work to split up the Ultimate Class whenever there's an opportunity. Because Miss Tian is described as a beautiful woman, she is often jealous of her getting all the attention. This character disappeared before the end of KO One.
