SK8 the Infinity (Simuldub)

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 from the beef against Adam have yet to heal, and with MIYA's advice, the group heads to Miyakojima for some hot spring therapy.

Injuries healed, Reki enjoys skating as he did before, but realizes anew just how much difference there is in skill between himself and Langa.

Langa enters the tournament that will determine the apex of "S." However, Reki isn't going to enter. Due to his inferiority complex against Langa, Reki separates himself from Langa.

Langa makes it past the qualifiers and will now face JOE. Langa has a hard fight against JOE's extraordinary power skating, and Langa feels the pressure. He feels bewildered by his emotional changes he feels there.

The battle between Cherry blossom and ADAM was decided by a painful blow by ADAM. Kikuchi challenges himself to the main tournament with his own set of emotions in order to stop ADAM.

I skate because it's fun. Reki remembers his origins of skating and deepens his bond with Langa. However, by doing so, ADAM targets Reki, and Reki must now go up against ADAM.

The battle between Reki and ADAM was won by ADAM. However, Reki was the one who was enjoying the beef. Seeing him, Kikuchi realizes that Langa is the only one who can give ADAM salvation, and drops out from his race against Langa.
