Haikyu!! (3-in-1 Edition), Vol. 2

Karasuno's training camp kicks off with a bang, and the moment they've all been waiting for finally arrives—the revival of the long-standing rivalry between the Cats and the Crows! Karasuno's practice games against Nekoma reveal all the cracks in their teamwork, and they'd better patch things up if they're to stand a chance in the Inter-High qualifiers. Team Karasuno realizes that their chances are even slimmer when they see who they're up against in their block: Aoba Johsai and the Iron Wall of Date Tech!
