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…

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. Miya teaches Reki a difficult skate trick that might help him win this reckless challenge. After intense training with his friends, Reki’s beef against Adam finally begins!

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 and Langa seek out Cherry blossom and Joe to hear more stories about Adam. There, a tactical meeting in order to win against Adam is held. Will Langa be able to defeat Adam’s impregnable Love Hug?

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…

Injuries healed, Reki enjoys skating as he did before, but realizes anew just how much difference there is in skill between himself and Langa. Gradually, Reki becomes tormented by an inferiority complex. They stop seeing eye-to-eye… And just then, Adam makes a certain announcement.

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…

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. And the race between Adam and Cherry blossom takes place. Cherry blossom had a certain conviction against Adam. Adam’s expression changes. The past between the two of them is revealed.

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.

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!
