After competing in the Inter-High, the Karasuno High School volleyball team tries to redirect their focus, with the goal of winning the Spring tournament. Upon receiving an invitation from their long-time rival Nekoma High, Karasuno accepts to join a major training camp featuring several prominent volleyball teams from Tokyo, as well as some national-level players. By competing against some of Japan's toughest squads, they aim not only to refine their abilities but also to develop new offensive strategies to bolster their strength. Additionally, Hinata and Kageyama work on creating a more potent attack, one that might be capable of breaking through even the strongest blocks. Confronting what could be their final opportunity for victory before the senior members graduate, the Karasuno volleyball team must resolve their conflicts and train more intensely than ever if they wish to defeat formidable foes, both familiar and new—including their archrival Aoba Jousai and its world-class setter, Tooru Oikawa.
