Karasuno High School Volleyball Club has challenged Aoba Johsai High School to a practice match. But even before the match begins, Hinata's anxiety level reaches maximum. And Kageyama has a "reunion" with his ex-teammate Kindaichi, who now attends Aoba Johsai.

The Hinata-Kageyama combo is back in form again, they won the next set, Karasuno has cornered Seijoh, and they're one step closer to victory. But at that time, Seijoh's captain Oikawa who was out on hiatus visits the court. How does Karasuno respond to super-offensive setter Oikawa's powerful serves?
