SK8 the Infinity - S01

High school student Reki Kyan is passionate about one thing: skateboarding. When night falls, he heads to "S," an illegal underground race inside a mine where skaters compete in highly dangerous situations. After a loss that leaves his skateboard destroyed and his arm broken, Reki can't practice at all. While working, Reki runs into his new classmate, Langa Hasegawa, a half-Canadian, half-Japanese boy with no skateboarding experience. Langa is in desperate need of money. After they both visit "S" when tasked by Reki's boss, they get into trouble and are forced into a bet that requires Langa to skate in a race. But the mysterious transfer student holds a trump card Reki doesn't know about, one that might help him win the race in the most unexpected way.
