Koyuki visits an instrument shop and practices some more. The school year ends. Next Momoko meets Koyuki accidentally going in Saitou's place and decides to go with him to check whether he works there. Koyuki tries to sell off Saitou's pornographic magazines.

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.

Ryusuke (along with Beck and Prudence) get kidnapped by Sykes, who takes him to meet his uncle, the bluesman John Lee Davis, who wanted to know who had stolen Prudence. Upon meeting Davis, one of his musical inspirations, Ryusuke has a jam session which overwhelms his idol, so much so he convinces Sykes not to kill him. So, four days after his kidnapping, Ryusuke is returned, badly beaten, but alive (but Sykes keeps Beck and Prudence with him). As he asserts the situation to Taira and Chiba, Koyuki and Saku, who were looking after the fishing pond for Ryusuke, are visited by one of the managers of the Greatful Sound Festival, Kazuo Sato, who is ecstatic to meet Koyuki after seeing him sing in the Dying Breed's tour movie. Koyuki later gets the chance to see himself on the silver screen, along with Maho.

The band tries to improve the new song and Koyuki tries to write the lyrics, at Ryusuke's request. Saito tries to help Koyuki come up with some lyrics. Surprisingly for him, the lyrics written by Saito are much more well received than those he wrote himself, so much so Ryusuke rewords the song in English. The band later departs for the Greatful Sound grounds, where they will perform on the smallest of the three stages. Ryusuke reveals Sykes' conditions to Chiba and Taira: he will have the rights over the band's next releases, as well as the promotion over the band. Ryusuke also reveals that he, in turn, established one condition on his own: Sykes will have to leave the theft of Beck and Prudence, if the band gets the highest attendance of the festival. Koyuki and Yoshito make a bet: if Maho comes to see Yoshito, then Koyuki must give up on her. Koyuki later is approached by a foreign band to perform for them, but the performance goes awry because of his inability with English and he is booed off the stage.

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.

As Beck's set finishes up, the reality that it's Beck's last performance finally sets in. Koyuki and Maho realize their love for each other and time goes on and the members of BECK move on with their lives. One month and a half later, Koyuki gets an unexpected phone call from Kazuo Sato, who takes her to a meeting with none other than Sykes, who had seen him perform at Greatful Sound and expresses his desire to produce a solo album for Koyuki, but he politely refuses. With Ryusuke missing, Chiba wanting to assemble his own ramen shop, Taira in another band and the news that Saku will transfer to another school, Koyuki's uneasiness returns day by day, even more so after he and Saku part ways.
