Karasuno High enters the Inter-High Volleyball Tournament and immediately proves they're "flightless crows" no more. After their first match, Karasuno dukes it out against Date Tech High and their famous Iron Wall, which shut down every spike of Karasuno's ace, Asahi, during a previous match. Karasuno, however, breaks through the Iron Wall this time and proceeds to the Round of 16. The newly rejuvenated Karasuno fights Aoba Johsai High and seeks to have the same outcome as their first practice match.
Shouyou Hinata, after losing to Kitagawa Daiichi Junior High's setter Tobio Kageyama in his first official volleyball match, transfers to Karasuno High, intent on finally having a proper volleyball team and getting his revenge on Kageyama. Upon arrival at Karasuno, however, Hinata finds out Kageyama has also gone to Karasuno. Initially at odds with each other, the two form an oddball combination and fight together with the other members of the volleyball club. Karasuno reunites with a former rival school, Nekoma High, in a practice match and reignites their school rivalry.
Ever since having witnessed the "Little Giant" and his astonishing skills on the volleyball court, Shouyou Hinata has been bewitched by the dynamic nature of the sport. Even though his attempt to make his debut as a volleyball regular during a middle school tournament went up in flames, he longs to prove that his less-than-impressive height ceases to be a hindrance in the face of his sheer will and perseverance.
