From Entropy:

Ryouhei Hayabusa, named after the nearly extinct Peregrine Falcon, no longer sings in public after his chorus teacher removed him from the choir, saying he has a "beast-like" voice. But one day when Saino, a first year, overhears Hayabusa singing, he asks Hayabusa to be the lead singer of his band. Saino then tells Hayabusa that there is a special quality about his voice…After meeting the disillusioned girl Azusa at the beach, Hayabusa immediately falls in love with her. Hayabusa decides to sing again, if not for himself, then at least for she who’s also searching for something.
