Beck: Mongolian Chop Squad Episode Rating Graph

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.

At the fishing pond the band talks with Kazuo about Greatful Sound. She wants Ryusuke to ask Eddie to come. Ryusuke agrees, but he also wants Beck to play although Ran is strongly against it. Ryusuke says that he'll get Sykes' support in order to get Beck to play. After the movie, Yoshito announces that he's going to play in Greatful Sound along with Belle Ame. Later, Ryusuke explains a dream he had, which is the same Koyuki had some days ago, in which dead rock stars appeared picking up trash (meaning they are cleaning up after Beck). Incidentally, Saku and Taira had had such a dream as well. Later, Maho sneaks into Koyuki's house and decides to sleep over, making him ponder about their relationship. The next day, Koyuki becomes the talk of the school due to his appearance at the Dying Breed movie, while Ryusuke gets in touch with Sykes.

Ryusuke talks with Chiba and Taira about his talk with Sykes. Back at school, Hiromi talks with Koyuki and Saku about playing guitar. Ryusuke wants to make a new CD, and proposes they write new songs for it. Later on, Ryusuke, Taira and Saku go to a live show in which Chiba is performing with another band, knowing that he is doing so just out of worry that Beck may not take off as quickly as he would like. That night, when Maho comes over to Koyuki's house again, Page (which Koyuki is taking care of for Saito, who is on a business trip) flies off and they go looking for him, while they start commenting on how common Koyuki thinks himself to be, though Maho has quite an opposite opinion. Later at home, Koyuki starts strumming an improvised melody on his guitar, so beautiful that it brings Page back and makes him sing to it. The next night, while Sykes takes Ryusuke for their business meeting (where he will impose his conditions for Beck to perform at Greatful Sound), Koyuki goes further into his self-thought song (which will become "Slip Out"), eventually showing his progress to Ryusuke. Despite the amateurism of the production, this song gives Ryusuke the push he needs to take Beck into Greatful Sound.

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.

The Greatful Sound festival is on, with Belle Ame on the primary stage, Malcolm (a Sykes-managed rapper) on the second stage, and Beck on the smallest third stage. Veteran Beck members think that if they fail to get more people than the other stages they should retire. Ryusuke mentions that he agreed to the bet because of the dream and then says some harsh words to Chiba, who runs away. The band starts to drift apart, with Taira standing for Chiba, as he goes around the festival site looking for his friend with Koyuki and Saku's help. Eventually, the three remaining band members think of quitting, due to the rain and being unable to find Chiba. Against the odds, Koyuki decides to go up on stage with only an acoustic guitar and starts playing a cover of "I've Got a Feeling" Shortly into the song he is accompanied by Saku; they start to make the crowd sway and flow with the song.

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.

Koyuki plans to revive Beck and sets out to get the band together. After talking to Chiba and Taira and getting them to join, Saku finally makes his way back to town to join up with the others and the band is finally back together (except for Ryusuke, who is making a living as a street musician in New York City when John Lee Davis approaches him offering help in anything he might need). Great news comes in the form of an invitation to tour with a band in the United States of America, and along the way they end up meeting Ryusuke again at Seattle. Leon Sykes also gets arrested. Beck plays a gig, all of them including Ryuusuke, their future is told in the manga (which also chronicles the lead-up to the US Tour in more detail).
