Yuzuki is Tetsuya Kuroko's little sister, and like him, she shares the same passion for basketball. But for some reason she keeps saying it's impossible for her to play. Why does she say that, and what hides behind that smile of hers? The story follows Yuzuki through her days as a freshman and new manager in Seirin, and her past with the generation of miracles. There is romance in it, but who it is with, I'm not going to tell.......for now.
