Fuyumi Ootori-Shido is Kyoya's older sister. She is shown to be a bright and sweet-natured young woman who is married, though she seems to spend considerable time with her younger brother and is friendly with Tamaki, who shares an interest in commoner cuisine with her. Fuyumi appears in Ep 24 - And so Kyoya Met Him! which is primarily a flashback of Kyoya's meeting Tamaki and their initial interactions while both are in middle school.
