Yukio "Koyuki" Tanaka's life was altered forever when he came to the rescue of a peculiar-looking dog, named Beck, from a group of bullies. This act led him to meet Ryuusuke "Ray" Minami, an ex-member of an eminent rock group and a skillful guitarist. Koyuki was astonished by Ray's guitar proficiency when he was brought to their former band's headquarters. Captivated by the allure of western rock culture, Koyuki set out to learn guitar and aided Ray in fulfilling his dream of forming the ultimate rock band. With the assistance of Ray's sister, Maho, and a few other musicians, they established their band, Beck, and commenced an exhilarating journey towards glory in the Japanese rock music realm. The account of Beck illustrates the band's experiences and triumphs as they strive towards achieving triumph.
