Chiyoko is the daughter of the director of the skating association and the ace of the Japanese skating world. She is paired with Tsubasa, the number one young skater. Then came along a delinquent girl named Kunimoto Yuri. She was considered a candidate to win the previous year's competition, but had an accident on the day of the competition, lost her mother, and left the skating world with an ugly scar on her leg. Yuri, however, gave a brilliant performance that showed no signs of her injury nor her two-year break. Chiyoko suddenly declared that she will form a skating pair between Yuri and Tsubasa without their approval, and that she will devote herself to coaching them.
