Sora Kurumatani is short and as scrawny as a stick figure, but he loves basketball with a burning passion. Unfortunately, on his first day at Kuzuryu High, he learns that the school's supposed basketball team is nothing of the sort. Instead of a haven for aspiring athletes, the gym has become the home turf for a gang of thugs, delinquents and perverts whose only skill at dribbling involves drooling on the floor while peeking into the girls' locker room. But since Kurumatani has to play to fulfill a promise made to his ailing mother, he'll have to take these sour lemons and squeeze-play out a winning basketball team somehow. Impossible? Perhaps. But with the help of a counselor and members of the girls' club, he'll do his best to get them all on the rebound in AHIRU NO SORA!
