Kai Qu is a witch and a professional Quidditch player of Chinese nationality. She served as a Chaser for the Chinese National Quidditch Team during the 2014 Quidditch World Cup. Her existence and role are detailed in supplementary materials written by J.K. Rowling (Pottermore).
Kai Qu's only documented appearance in wizarding history is as a key player for the Chinese National Quidditch Team that competed in the 2014 Quidditch World Cup, which took place in the Patagonian Desert (Pottermore). Playing in the position of Chaser, she was part of a celebrated offensive line alongside fellow Chaser Deng Quon. During the first round of the tournament, the Chinese team faced the Nigerian National Quidditch Team. Despite the Chinese Chasers being described as a “marvel” in their performance, the team was ultimately defeated by Nigeria, with a final score of 300 to 100. This loss eliminated China from the tournament (Pottermore).
There is no known description of Kai Qu's physical appearance or personality.
While no specific possessions are mentioned, as a qualified witch and professional Quidditch player, Kai Qu would have owned a wand and a professional-grade broomstick.
Kai Qu's only known professional relationship was with her teammate on the Chinese National Quidditch Team, fellow Chaser Deng Quon. No information is available regarding her family, friends, or other associations.
The name “Kai Qu” has Chinese origins.
When combined, her name could be interpreted as “Song of Victory” or “Triumphant Song,” a fitting name for a competitive international athlete.
Kai Qu is a character created by J.K. Rowling specifically for the Pottermore website (now Wizarding World) as part of the expanded universe content. Her story appears in the “History of the Quidditch World Cup” articles and the fictional live-report coverage of the 2014 tournament, written from the perspective of Ginny Weasley (Potter). She does not appear, nor is she mentioned, in the original seven Harry Potter novels or any of the film adaptations.
