Teikou Middle School is well known for its celebrated basketball team, which gave rise to the legendary "Generation of Miracles": a group of five prodigies, each possessing distinct talents, who were regarded as unbeatable by the time they reached their third year. Yet, clouded by arrogance, they parted ways, attending separate high schools after graduation. Taiga Kagami, who has just come back from America, joins the basketball squad at Seirin High School looking for formidable teammates. There, he encounters Tetsuya Kuroko, a player who appears unremarkable, only to discover that Kuroko was the "Phantom Sixth Man" of the Generation of Miracles: an unseen player who relied on his flawless passing to assist the team from the sidelines. Together, they vow to overcome the Generation of Miracles and establish the Seirin basketball team as the top one in Japan.
