Kuroko no Basket follows the journey of Tetsuya Kuroko, the "Phantom Sixth Man" of the legendary Generation of Miracles middle school basketball team, as he enters Seirin High School.
Alongside his new teammate, Taiga Kagami, a naturally gifted player returning from America, Kuroko aims to prove that he can still be a strong player in his own way, despite his perceived lack of individual talent.
They form a dynamic partnership, with Kuroko acting as Kagami's "shadow" to support him in becoming the best player he can be.
Together with the rest of the Seirin team, they strive to win the Interhigh championship, but face a significant challenge in the form of Kuroko's former teammates, the Generation of Miracles, who now attend rival schools.
