Generation of Miracles and The Phantom Sixth Man are known as the strongest basketball players of all. That's what all people thinks. Until one day a girl came to Teiko Junior High. She's a childhood friend of one of The Generation of Miracles, the shooting guard, Midorima Shintaro. And also, his basketball teacher. And her skills was beyond all of the miracles.
But what happen if fate brought her and Midorima together again after a very long time?
What happen if the bond between them started to fall apart? And she couldn't do anything to prevent the worst possibilites.
What happen if a "promise" is the only thing that's left to a happy ending?
Can everything comes back to normal?
Or even become worse?
