The Fandom Post is reporting that the Netflix app is showing that the third season of the Kuroko’s Basketball anime is scheduled to begin streaming on the service on September 1, 2021.
The story of the third season of Kuroko’s Basketball is described as:
In the final season of Kuroko no Basket, Kuroko goes head-to-head with his old teammates once more as he attempts to show them that individual skill is not the only way to play basketball. His firm belief that his form of basketball, team play, is the right way to play the sport will clash with the talents of a perfect copy and an absolute authority. Kuroko and the rest of Seirin High ultimately have one goal: to win the Winter Cup and overcome the strength of the Generation of Miracles, who have long dominated the middle and high school basketball scene.
