Obsession.Thanks to Hinata's surprising left-hand attack, Karasuno wins another set from Shiratorizawa, and moves on to the final and fifth set, the set that will decide the winner! The final set is going to be quick, ending at fifteen points, so Karasuno switches setters from Kageyama to Sugawara to let him rest. However, Satori is predicting Sugawara's every move, and scores a point successfully. Sugawara follows up with a mix of synchronized attacks, in which he spikes and scores. The match continues as such, but Tsukishima is injured while trying to block Ushijima's spike, and is sent to the infirmary, causing Karasuno to fall behind badly. Episodes of Satori and Ushijima's lives when they were young are also shown.
