Tsukiko Saionji

Beautiful and wealthy, her social status equates to that of Kouki. Though she appears rather innocent, Tsukiko originally is not very sweet at all, but her friendship with Tanpopo gradually softens her personality and she becomes more caring and loyal. She has her heart set on marrying into the Kugyou family, specifically Kouki, although she eventually gets over this longing after realizing Kouki and Tanpopo's feelings for each other.
