Arianne, a little fairy princess, gets ready for the spring festival in Lilliweather with the fairy children of the land. But their elf friend, Fife, tells her about an evil ogre, Ogun, who kidnapped a fairy child, Jin, at his hut in the dark woods. The way to destroy the ogre, Fife says, is through the help of a magical Thunder Elk, who promised to protect the fairies since the distant past.
