After causing chaos in the Witch Forest, Yadamon's mother, the queen, banishes her to the human world. This is both to teach Yadamon a lesson and because the queen secretly loves human magazines and books. While Yadamon is in the human world, the queen keeps a close watch on her—but this becomes a problem because the queen falls asleep almost anywhere she goes.
The human world has become extremely high-tech, and many animals have gone extinct. Yadamon ends up on an island called Creature Island, where genetically re-created species are being produced. There she meets Jean, along with his parents Edward and Maria.
Yadamon stumbles into many misadventures in the human world due to her curiosity, causing plenty of trouble for the humans and for her guardian fairy, Timon, who has the ability to stop time.
As Yadamon learns to adapt to the human world and use her powers, a new threat arises. Kira, the evil witch who was sealed inside a volcano by the queen and the great witch Beril, has escaped. She seeks revenge and has set her sights on both the humans and Yadamon.
