Yin Xiao Feng is the Bronze counterpart to the Gold dimension's Qiu Qiu. She is of unknown origin, and became like sisters with Xiao Yang. They were adopted together, and later has the same Yi Neng ability as Xiao Yang. Even though her adoptive parents were killed and her and Xiao Yang were separated, they stayed close and regularly met up. This is how Xiao Feng realizes something must have happened to Xiao Yang after she fails to meet up with her at their regularly scheduled time. Xiao Feng has a huge sense of loyalty to Xiao Yang, even going so far as to join the KO Bad Girls just to continue Xiao Yang's wish of protecting Wang Charlie, even though she didn't know him that well.
