Seirin's basketball team advanced to the semifinals of the Winter Cup after their victory over Yousen High. The competition includes formidable opponents Kaijou, Rakuzan, and Shuutoku, each boasting a member of the Generation of Miracles. Seirin recognizes the challenge they face in their quest to win the Winter Cup. In the last season of Kuroko no Basket, Kuroko squares off against his former teammates, aiming to demonstrate that basketball is not solely based on individual abilities. He firmly believes that teamwork is essential to playing the game correctly, but will clash with opponents who possess a perfect replica and absolute authority. Despite Kuroko's efforts to prove the correctness of his style of basketball, Seirin High's ultimate goal is to win the Winter Cup and to surpass the Generation of Miracles' dominance in middle and high school basketball.
