A shy, pretty, young lady who considers dogs her brothers and sisters. She promptly fell in love with Mitaka when they met in "omiai," although Mitaka had an allergic reaction. She was initially worried about the relation between Mitaka and Kyoko. Asuna's family name, Kujou, means "Ninth Avenue" in Kyoto, and implies that she is a member of the ancient aristocratic Fujiwara clan. Kujou is a homophone for Cujo, Stephen King's infamous demon dog, but it is unclear whether Rumiko Takahashi intended this as a pun.
