The nationals arc finally arrives, but the real game is watching Hinata claw his way back into relevance when the team moves on without him. Haikyu!! has always known that volleyball is secondary to the quiet violence of self-doubt, and this season makes that explicit. The animation doesn't just capture spikes and receives anymore, it captures the moment a player decides they're not done yet.

Karasuno's volleyball team has finally qualified for nationals, but before they step onto that stage, the squad splinters. Kageyama gets selected for an elite all-Japan training camp, while Tsukishima earns a spot at a rookie camp for Miyagi first-years. Hinata, left without an invitation and afraid of falling behind, turns up at that same Miyagi camp anyway. The only role he gets there is ball boy, yet he treats it as a real chance, studying his own game and everything happening on the court to see what he can use. As the national tournament draws closer, the whole team works to shore up its weaknesses and sharpen its skills. This sports series mixes comedy and drama with its volleyball.
