The basketball team of Teikō Middle School rose to distinction by demolishing all competition. The regulars of the team became known as the "Generation of Miracles". After graduating from middle school, these five stars went to different high schools with top basketball teams. However, a fact few known is that there was another player in the "Generation of Miracles": a phantom sixth man. This mysterious player is now a freshman at Seirin High, a new school with a powerful, if little-known, team. Now, Kuroko Tetsuya, the sixth member of the "Generation of Miracles", and Kagami Taiga, a naturally talented player who spent most of middle school in the US, are aiming to bring Seirin to the top of Japan, taking on Kuroko's former teammates one by one.
