In Teikō Junior High, there was a basketball team so strong, the five were called the Generation of Miracles. But a strange rumor existed, that there was another player amongst them, a phantom sixth man.


In Seirin High School, Taiga Kagami joins the basketball team, leaving an intimidating impression. Unnoticed, Kurokojoins too and the coach, Riko Aida is shocked to see that he was actually part of the Generation of Miracles. At the first training, Riko inspects the new players and is amazed by Kagami's body physique, but doesn't see Kuroko at all. She, Kagami and the whole team are confused whether or not he is really part of that strong team.


After training, Kagami and Kuroko meet at a street basketball court and Kagami gauges his strength by playing him one-on-one. Kagami is disappointed when he sees that Kuroko is very weak in basketball. He tells Kuroko that he should quit basketball, but Kuroko says that his strength is different from Kagami's.


The freshmen are tested in a practice match

At the next training, the freshmen have to play a match against the second-years. Kagami is proven to be a raw talent in basketball and dunks his way to take the lead. But the second-years stop him by triple-teaming him in defense and they make a comeback. During the match, Kuroko is again seen as weak and gets the ball stolen multiple times. When the other first-years are demotivated, Kagami gets heated up, but is calmed down by Kuroko. Kuroko later asks for the ball, gets it, but immediately redirects it toFurihata under the basket, who scores. Kuroko's strength is finally shown and his invisible passes get through. The first-years close the gap to one point and Kagami eventually finishes it with a ferocious dunk.


Later, Kagami and Kuroko meet again and Kagami launches his ambition to become Japan's best basketball player. To do so, he must beat the Generation of Miracles. Kuroko says that he's far from their strength, but that he will help as a shadow to Kagami's light to make him the best.
