The third quarter starts with Kuroko remaining on the sidelines.

Seirin begins the counter attack using their run-and-gun method, suprising the Kaijo players and the audience. 

Kaijo fiercely fights back with the return of their ace player Kise. The crowd goes wild from their all-out efforts to make a comeback and all start to cheer only for Kaijo. 

Kagami shows extraordinary growth and treats the Kaijo double-team as if it is nothing, overwhelming them as their ace player Kise remains on the bench. Kaijo stays determined to stay within reach of Seirin, but they cannot stop the momentum that favors Seirin and start to gradually fall behind.
