Yahiro Saiga

A carefree young man with a sinister side, Yahiro has known both Kei and Akira since they were children. He holds the distinction of having beaten Kei once during their childhood in a game of tag which Kei lost because Yahiro had locked the door to the roof to prevent Kei from winning. Yahiro attends Kokusengakuen, another high school, and is the heir to the Saiga Financial Group, a group that is even higher in status than the Takishima group. When he was young, Yahiro had no friends, for the most part because his attitude prevented him from making anyone smile or laugh and made them cry instead. He chose not to become friends with anyone until he met Sakura.
