Once upon a time, a team of basketball prodigies rose to the top by demolishing all competition. This team became known as the Generation of Miracles, as they are all in the same year group and they were considered children of miracle. After junior high school ended, these five stars went to different high schools with top basketball teams. However, a fact few people know is that there was another player accompanying the Generation of Miracles, a Phantom Sixth Man. This mysterious player is now a freshman at Seirin High, a new school with a powerful, yet little-known, team. Now, Tetsuya Kuroko, the sixth man formerly with the Generation of Miracles, and Taiga Kagami, a naturally talented player who spent most of junior high school in America, are aiming to bring Seirin to the top of Japan, taking on Kuroko's old teammates one by one. The Teiko Middle School Basketball Team. The school that produced three perfect seasons in a row, with five once-in-a generation players, called "The Generation of Miracles." There was another player who all of them respected... A legendary 6th player. An up-and- coming power player, Taiga Kagami, is just back from America. When he comes to Seirin High School, he meets the super-ordinary boy, Tetsuya Kuroko. Kagami is shocked to find that Kuroko isn't good at basketball, in fact, he's bad! And he's so plain that he's impossible to see. But Kuroko's plainness lets him pass the ball around without the other team noticing him, and he's none other than the sixth member of the Miracle Generation. Kuroko makes a pact with Kagami to defeat the other members of the Miracle Generation, who have all played basketball at other schools. A battle of light (Kagami) and shadow (Kuroko) begins!
