SK8 the Infinity

Langa, a transfer student from Canada, meets Reki, a high school student who loves skateboarding; Reki seems to be hooked on S, a dangerous and secret race that is held in an abandoned mine.

Langa, winning against Shadow, turns out to be experienced in snowboarding; as he gains attention in the S community as the mysterious rookie, Langa wants to feel the tingling sensations felt during the beef again.

As Langa quickly improves, MIYA the 7th grader and candidate for the Japanese national team challenges him to a beef; Reki's worries aside, Langa accepts the beef.

ADAM, a legendary skater and the creator of S appears in front of Langa after his victory over MIYA; Reki challenges ADAM to a beef when he insults MIYA, and ADAM accepts on the condition that he gets to race against Langa, as well.

Reki suffers heavy injuries in his beef against ADAM; now, Langa must go on a beef against ADAM; Reki doesn't want to feel what he has in the past and tells Langa to stop, but Langa's strong determination is unwavering.

Reki's injuries are yet to heal, and the group head to Miyakojima for some hot spring therapy. They bump into Cherry Blossom and Joe there.
