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.

The band tries to raise some money and Chiba finds out that Dying Breed is coming to Japan. Later on Koyuki talks to a teacher about his decreasing grades. Momoko asks the band to enter the school festival.
