Kou Hayami is Club Grand Blue’s top dancer with a scarred past, which puts him at a distance from his co-workers. His only drive to continue dancing was his promise to surpass his dead father. Everything in Kou’s world seemed black, and only in dancing can he see color. When newcomer Nagisa joins Grand Blue, Kou’s first words to him were “”You’re awful,”” making Nagisa dislike him. The two were complete opposites, which made it worse. That is until Nagisa sees Kou’s passionate dance and makes it his goal to surpass him.
