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.

Dying Breed performs in concert live in Japan, with Koyuki unexpectedly guest singing. Later on, Koyuki and Izumi meet again and she invites him for night-swimming, much to Maho's chagrin when she finds out. Meanwhile, Ryusuke finds out that somebody close to him has died.
