Yumi Shirayanagi was the most popular girl at Yuu's old high school—basically the madonna of the place. She got interested in him after he saved her from a car accident, though he was actually the one who caused it in the first place. The relationship didn't last long though. Once Yuu switched over to Hoshiumi Academy, she broke up with him.
