Peace has returned to Castalot High School after the events of the Fall Formal. And none are more happy with the peace than Burst Stream. Especially since he got his life back to normal after Sunset Shimmer and Goldenrise tried to wreck it. However, this peace is short-lived as Burst Stream notices a strange card deck near his bed. But this time, it's blank instead of having the crest of a dragon that he remembered talking to. And all the memories of the Fall Formal have given Burst several questions: Where did the dragon that gave him the deck come from? Who made the mysterious armor he'd donned to fight Sunset and Goldenrise? But most important of all, what's a Kamen Rider? There's only one way to find out. HENSHIN!
