A high school band is popular in their small hometown in Okinawa. The band belts out original pop songs with such energy and precision that they have fired up the passions of all who see them including the attention of a Tokyo record label scout bent on producing them. As the band members enjoy the happiest days in their young lives with full of hopes, a tragedy takes place, destroying their hopes and spirit. Then, a girl who lives on the U.S. army base suddenly appears with a demo tape of a song.

As a band plays for a crowd in a certain town square in Osaka, a young man rushes to the stage, grabs the microphone and begins to sing. The crowd is blown away by his vocal, but soon the band manager Kasumi discovers that he has no memory of his own life. Kasumi becomes interested in working with him anyway, and gives him the nickname "Pochi-O". Before long, Pochi-O is accepted as the lead vocalist of a band, but a major problem from his past will soon come back to haunt him.
