After competing in Inter-High, Karasuno High School's volleyball squad seeks to redirect its focus toward winning the Spring championship for the team.
Upon receiving an invite from their long-time foe Nekoma High, Karasuno accepts participation in a sizable training camp featuring numerous prominent Tokyo volleyball teams and even top-tier national-level players, alongside many other elite squads.
Competing against some of Japan's toughest squads, they aim to refine their abilities and devise innovative dynamic, new offensive strategies that will bolster the team for further new development.
Additionally, Hinata and Kageyama strive to create a new stronger attack tool in that could shatter even the toughest blocks.
Confronting what could be their final chance to claim victory before the senior players graduate, Karasuno's volleyball squad must reconcile internal conflicts and train harder than ever to surpass formidable foes—both old rivals and new challengers—including Aoba Jousai and its world-class setter Tooru Oikawa in the fiercely competitive spring tournament arena.
