Touka Ryuumonbuchi

As a prominent member of the Ryuumonbuchi clan's four heavenly kings, this wealthy socialite thrives on being the center of attention. Her intense desire for the spotlight fuels a deep-seated rivalry with Nodoka, whom she resents for achieving fame as a middle school champion. Driven by both prestige and competition, she maintains a commanding presence within the series, though her character's gender and name are notably altered in the King's Tile Draw adaptation.
