Beck: Mongolian Chop Squad - S01

Fourteen-year-old Yukio "Koyuki" Tanaka is a downcast boy with no direction in life. That changes when he saves an odd-looking dog named Beck from being picked on by local kids. The dog's owner, 16-year-old Ryuusuke "Ray" Minami, is a rising guitarist and a former member of a popular rock band. After Koyuki runs into Ray again at a diner, the older boy takes him to his old band's practice space and stuns him with his guitar playing. Gradually drawn to the allure of western rock culture, Koyuki decides to pick up the guitar while helping Ray chase his dream of leading the ultimate rock band. Along with Ray's younger sister Maho and a few others, the two start their career in rock by forming a band called BECK. Beck follows the group's struggles and successes as they build their fame across Japan.
