Haikyu!! Volume 13 features story and art by Haruichi Furudate.

Karasuno fights their way through the preliminaries and wins, earning them a spot in the October Qualifier Rounds of the Spring Tournmanet. Their first opponent is a team of partiers from Johzenji whose motto is “play hard”! They're a highly unorthodox team that improvises crazy attacks on the fly, leaving Karasuno baffled on how to counter them!
