Fuyumi Ootori is Kyoya's older sister. In the anime, she appears during Kyoya's flashbacks about his first meeting with Tamaki. She clearly cares for her younger brother and tries to help him in life; apparently she is somewhat lacking in the areas of housework and organization, but she appears to be a kind-hearted person. It is revealed in the manga that she was married, but returned home later (for a short visit, which her father chided her for). Her husband's surname is Shido (矢道?). She and Tamaki are pursuing a tour of commoners' food together.
