Seirin High"s quarter‑final in the Winter Cup faces Yousen High, a team renowned for its tight defense. The core of Yousen"s "Shield of Aegis" is built around Atsushi Murasakibara, a former teammate of Tetsuya Kuroko from the Generation of Miracles, and Tatsuya Himuro, a talented player who has clashed with Taiga Kagami before.
Having been unable to settle their earlier rivalry, Kagami and Himuro decide that this high‑stakes contest will finally reveal who is superior. Meanwhile, Kuroko"s lingering resentment toward his old teammate adds extra heat to the court.
Should Seirin break through Yousen, their next challenge will be Kaijou High in the semifinals—another former teammate of Kuroko, Ryouta Kise, leads that squad. Disrupting Kise"s "Perfect Copy" will be crucial for Seirin"s success, yet this proves difficult once they see how Kaijou"s star has mastered the playstyles of all the Miracles.
