Snowfall on a Hot Night.
Reki Kyan partakes in S, an underground skateboard race, against Shadow, but loses, injures his left arm, and gets his skateboard set on fire as a result. The next day, Langa Hasegawa, is introduced in his class as a new transfer student from Canada. After encountering each other after school, Langa applies for a job at Dope Sketch, where he and Reki are given orders to deliver a skateboard to a client for his next race at S. Reki later discovers he had taken the wrong skateboard, and, as punishment, is ordered to race in place of his client against Shadow. Langa volunteers, and to everyone's surprise, he wins using his experience in snowboarding.
