Beck: Mongolian Chop Squad

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.

When Koyuki accepts Ryusuke's invitation to see his band perform live, he unwittingly sets down a path of self-discovery. But what Koyuki finds both disturbs and intrigues him, as the youngster uncovers the best and worst aspects of human nature.

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's guitar training is coming along slowly but surely, until Saitou decides to speed things up by entering him to play in the annual summer festival! Meanwhile, Ryusuke and Chiba put their heads together to come up with a name for their new band.

Taira, the newest member of Beck and the others have their first session together to start the band off on a good note. Koyuki's teacher is on maternity leave and a new cute teacher is introduced. As coordinator of the choir contest, she wants Koyuki to be the leader for the class to get them ready for the contest.
