After participating in the Inter-High, the Karasuno High School volleyball team shifts their focus towards dominating the Spring tournament instead. Nekoma High, their longtime rival, invites them to join a sizable training camp in Tokyo where they engage with numerous notable teams and even national-level players. By competing against some of the most resilient opponents in Japan, they aim to polish their abilities and develop new tactics to enhance their game. Hinata and Kageyama's goal is to create a powerful new weapon capable of smashing through even the toughest blockers. With graduation looming for the senior members, Karasuno's volleyball team faces what could be their final chance at success. They must mend their differences and train harder than ever to triumph over both old and new formidable rivals, including their archenemy, Aoba Jousai, and their exceptional setter, Tooru Oikawa.
