Gao Hai arrives at Area 11 with Li Xingke as his bodyguard. Greeting him on their arrival is the new Viceroy of Area 11, Calares, who has a large security force with him in order to allow the Chinese Federation a better understanding of the Britannians. However, Xingke is asked to release his weapon who instead cuts the belts of two Britannians causing Gao Hai to tell him that his actions were rude. Xingke apologizes and responds by stating that he wanted the Britannians to have a better understanding of the Chinese Federation. Their meeting is interrupted as an explosion was seen from Babel Tower.
Following that meeting, Gao Hai fell under Lelouch's Geass. And while under the influence of Lelouch's Geass, he grants asylum to the Black Knights within the grounds of the Chinese Consulate. Afterwards, Xingke questions Gao Hai's motives in following Zero. When Gao Hai claims Zero is more important than Empress Tianzi, Xingke sees this as disloyalty and executes him by slashing his throat.
