Prince Mackaroo, a noble from Fairy Land, accidentally slips through time from the Heian Era to modern Moonlight Town after finding a demon power scepter. While chasing demons with Cozmo, they notice the 'Fullmoon Road' shrinking and the Moonnight Pond drying up. A girl named Tsukimi warns that the 'Tear Rock' and the pond are drying, threatening to vanish the road unless they collect 10 divine spheres from the Heian Era before the full moon tomorrow. With only two days, Prince Mackaroo and his friends race against time to find the spheres and save the Fullmoon Road.
