While training in Sydney, Australia, Rin Matsuoka meets Natsuya Kirishima, Ikuya Kirishima's older brother, who is currently racing in international relays for cash prizes.

Rin doesn't hesitate to point out Natsuya's unhealthy habits, while Natsuya teases Rin about his divided thoughts regarding certain friends. Their camaraderie leads to a race aborted by rain with Natsuya returning to Japan for Ikuya, as well as to seek out Nao Serizawa, his own close friend since middle school.
