I'm Not Mature! (大人じゃねーよ!, Otona Janē yo) is the twenty-third episode of the Kuroko no Basuke anime.
Synopsis[]
The match between Tōō Academy and Kaijō High begins with Kaijō getting the ball. Ryouta Kise manages to pass Daiki Aomine, but Aomine steals the ball. Ryo Sakurai scores the first 3 points. Kise copies Sakurai's 3 point shot, but is easily blocked by Aomine. Yukio Kasamatsu regains the ball for Kaijō and scores a 3 pointer, and Kaijō tighten their defence. Kise then manages to stop Aomine's quick dribble and drive, and his Formless Shot. The 1st quarter ends with Kaijō leading 18-13. From the sidelines, Tetsuya Kuroko mentions that Aomine tends to improve as the game goes on. Tōō immediately catch up in the 2nd quarter. Kaijō calls a time out, and Kise asks his coach permission to use an unknown trump card.
