Kyuuka is a somewhat on the slender side, both weight wise, and curve wise, she does however have a few hints of female curves in her and they show thanks to her bodysuit. Out of all of the sprites on the YSS Asamoya she also has the smallest bust, reaching only an A cup. She has long, straight, golden blonde hair, and sea green eyes.

Kyuuka, like the season she is named after has a hot temper. She does on occasion show a softer side of herself, but to only a select few. Kyuuka becomes easily irritated when around her sister fuyu who she sees as the preverbial 'ice queen' and that is what that annoys her. She is smart, although tomboyish.

Kyuuka was created aboard the YSS Asamoya along with her sisters, fuyu, haru, and aki to help fill in some of the roles of the ship. Only being alive one day, Kyuuka has already met most, if not all of the crew, along with their commander, Shoi Yuriko Towa who helped settle a little dispute between haru, and aki.
