In order to prevent the star thief leader Rhettus from snatching the super star pet in the hand of the big card, the superstar agents returned to the sky star domain ten years ago to start a duel, and Rhedith got rid of the superstar agent and disappeared. Since you can't catch Radius, you can only start with a big card, and if you want to get in touch with a big card, you have to retake your driver's license to participate in the competition. Thus, the Superstar Agent begins the final chapter of his mission while racing. The superstar agents unite and rise to the challenge, defeat strange racing opponents, dismantle various intrigues and tricks laid by Retus, and finally successfully destroy the Star Thieves and complete the mission to save Superstar's pets.
