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, who was looking for a part-time job, heads to the “S” venue together with Reki as an assistant. There, the nemesis Shadow who caused Reki’s injury taunts Reki, and Langa, who has no experience skating, gets roped in, as well!

Langa, winning the beef 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 and decides to learn skating from Reki. Langa is bewildered with the differences from snowboarding, but thanks to Reki, he learns of the fun of skating and its infinite possibilities.

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. Miya’s high-level skating skills overwhelm the pair. Reki, who keeps Langa company during practice for his sake, notices something. And the time for the beef against Miya arrives. What Reki entrusts Langa with is…

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. They bump into Cherry blossom and Joe there, and end up having a beef to see who will be the first to make it along the path to the secret spring. A suspicious shadow descends upon them. It seems there’s a rumor that this island “has” something…

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. The absence of Reki drops a shadow onto Langa’s heart as the tournament qualifiers begin. As the skaters who will enter the main tournament are decided, the scene is in an uproar over a mysterious skater. The identity of that skater is…

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. Meanwhile, Reki realizes his true feelings but still hasn’t found an answer to what he should do.

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. An unexpected rematch against Adam. It's an opponent that planted terror in him with a crushing defeat, but Reki feels no fear. "Let's go head-to-head in the finals." An exchange of emotions with Langa. Reki challenges himself to beef against Adam.

The stormy 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. As Reki and Langa head into the beef against Adam, they make a certain promise. The finals between Adam and Langa will now begin!
