Yigao Wu is a member of the Yellow Heads gang that mostly operates in Kowloon, however, Yigao can be first seen in Wan Chai. Accompanying Liandeng Jing, Yigao goes with a few other members to the South Carmain Quarter where they are attempting to force people to leave the Yan Tin Apartments as part of a landshark operation. However, they are stopped by Ryo and Guixiang Lee.
Yigao returns to the Yan Tin Apartments a second time with Mengjia Zhang whilst Guixiang is practising Tai Chi outside the building and showing Ryo a new move. Yigao sends Mengjia in to attack Ryo but after seeing Mengjia defeated by Ryo the pair are quick to retreat. He refers to Mengjia as "brother", although they are likely not related.
Yigao appears again, attacking Ryo in the White Dynasty Quarter as part of a large group of Yellow Heads, including Yuan, who are attempting to kidnap Shuqin Zhang. He attacks alongside Jingmu Jiang and Wen Zhai, but is beaten again by Ryo.
