Koyuki Tanaka is in a dead end. At age 14, he has lost his passion for life. But a casual meeting of Koyuki with a young musician named Ryusuke is about to open a new path in front of him.

Koyuki hangs out with Ryusuke and finds out more about music, and meets his sister, Maho, who later takes Koyuki to see Beck, her brother's dog.

While Koyuki takes his first tentative steps toward learning guitar, Maho suggests that he'd be the perfect lead vocalist for Ryusuke's new band. But an accident threatens to shatter Ryusuke and Koyuki's friendship forever, as well as putting an end to Koyuki's musical aspirations-until help comes from a very unexpected source.

Koyuki and Saku become friends. Koyuki gets nominated for the most difficult swimming races in the school's competition. Koyuki takes Saku to see Beck's show.

The band tries to raise some money and Chiba finds out that Dying Breed is coming to Japan. Later on Koyuki talks to a teacher about his decreasing grades. Momoko asks the band to enter the school festival.

Dying Breed performs in concert live in Japan, with Koyuki unexpectedly guest singing. Later on, Koyuki and Izumi meet again and she invites him for night-swimming, much to Maho's chagrin when she finds out. Meanwhile, Ryusuke finds out that somebody close to him has died.

Mitty brings the cover design for the Beck band logo. Izumi meets up with Maho to clear the misunderstanding between them. During practice there's some tension between band members, who are pressured by the recording of the new album. But to make things worse, Koyuki has a fever and thinks he's holding back the band. Koyuki loses consciousness sometime during the night and dreams a star-studded vision of his first concert.

Gordie comes to see Eddie about the stolen stuff including Prudence. Then Eddie and Ryusuke talk about it on the phone. Koyuki still works hard to earn cash for the Telecaster and we can see a girl who works next door for the second time. At school, Tanaka finds out that one of Maho's friends is quite famous. Beck performs and is heard by Chicagoan records agent, named Frank Albin, allowing for a possible big break.

Koyuki talks with his boss about his band. Saku then joins Koyuki at Saito's swimming practice. Beck is allowed to perform at the Marquee's evening show as Hitode's support, because the manager really liked Koyuki's singing. Maho meets with record company executives. Ryusuke gets the American version of the band's record, and is utterly dissatisfied with the cover art because it depicts him playing Prudence, knowing the consequences that single picture would bring. Leon Sykes comes to Tokyo, and his first act there is cornering Ryusuke at his own house by the fishing pond.

After the band seems to break up before their time on the third stage, the band is slowly reforming just in time to play their hearts out for the growing crowd. Ryuusuke has returned after being given Prudence to play on and Chiba races back to the third stage after thwarting his kidnappers. Meanwhile, the worsening weather forces interruptions at the other two stages, frustrating Eiji and angering Sykes.
