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.
