Everybody knows that Itsuki is the most fearsome skater around. But, because he?s the best, someone will always want to take him down. Ikki and Team Kogarasumaru are in a bad situation - facing uber-team Sleipnir in an aerial battle on the back of fighter jets, while the clock ticks down for a loved one held hostage elsewhere. As the battle rages on, Sleipnir?s members reveal their true nature as lab-created experiments programmed with the need to fly. Can Ikki show them the way, or are they destined to be another disappointment?
