Karasuno manages to win the fourth set. The fifth set begins, but has a different set of rules: whoever gets 15 points first wins. Keishin sees that Kageyama is exhausted, and switches him out with Sugawara. Determined to hold up his end, Sugawara shows how he has improved.

The battle goes well beyond 15, as the fifth set for both teams enters the 20's. Shiratorizawa shows off individual strengths, and Karasuno continues to show the strength as a team. In a battle of volleyball philosophy, Karasuno and Shiratorizawa fight for who moves on to Nationals.
