Haikyu!! Temporada 4 Episódio 21

Because Karasunos plays become messy and the matchs rhythm gets thrown off, they change setters. Sugawara goes onto the court in place of Kageyama and because hes always seen things from outside the court, he says he knows whats going on, and Karasuno starts their counterattack. Meanwhile, after seeing the match from the outside, theres a change in Kageyama as well.
