The ramshackle basketball team that Sora Kurumatani's love for basketball forged from a collection of juvenile delinquents and random high school archetypes has made it past their initial training and practice games, but are they ready to compete in a real tournament? They'll find out as they face off against the far more seasoned and experienced team from Shinjo Towa Academy. But even if they dig down and find a way to play better than they've ever played before, there are more teams ready and waiting in the wings, including the relentless squad from Yokohama Taiei. The drama is intense both on and off the boards, as tensions fly, members of the fledgling team start to crack, and Sora's own situation hits a point that may tear the team apart in the second spectacular collection of AHIRU NO SORA!
