7

Oikawa returns for Aoba Johsai. He is revealed to be their captain and their true setter. He also is Kageyama's original senpai. When Oikawa comes up to serve, he starts hitting perfect serves to Tsukishima, resulting in an ace every time. It isn't until Sawamura changes their formation that Karasuno is finally able to win the match against Aoba Johsai. However Oikawa reveals when they next meet, Aoba Johsai will be using all its aces from the start, and a very different result will be expected. On the bus ride home, Sawamura reveals that Karasuno also has a few surprises. Their libero, Yu Nishinoya, is about to return and completely change Karasuno's dynamics as a team. (Source: Wikipedia)
