Kuroko Tetsuya and Kagami Taiga joined the Seirin High School basketball team. Compared to Kagami, who has an excellent sense of the ball, Kuroko is a player who "has almost no presence" on the court. But in fact, Kuroko was a member of the basketball team of Teiko Junior High School, a strong basketball school. He fought side by side with the five geniuses known as the "Miracle Era" and was active on the basketball court as the "Dream Sixth Man". The duo of "Shadow" and "Light" became the main force of the school team and led Seirin High School to successfully enter the winter trials. In the trials, they defeated other strong teams with members of the "Miracle Era" and won the national championship. At the end of the summer vacation after the two were promoted to the second year of high school, a streetball team "Jabberwock" composed of a group of American basketball geniuses around 18 years old visited Japan and played a friendly match with the Japanese men's basketball national team. They defeated the Japanese team with overwhelming strength and laughed at them. This action angered Kagetora, the father of Reiko, the coach of the Seirin High School basketball team. The former Japanese basketball player decided to gather Kuroko and Kagami, as well as other members of the "Age of Miracles", to temporarily form a dream team "VORPALSWORDS", vowing to take revenge on "Jabberwock"! The most intense decisive battle has begun!
