I think this would work better as a novel. A girl named Miju is an exchange student to Germany from Japan. She makes almost instant friends with Bibi. Just days later they have convinced their parents to let Bibi travel back to Japan with Miju and be an exchange student. The two girls are connected by magic. Bibi is a witch, and Miju is not well explained. Overall the story was nice and easy to follow, but underdeveloped and at times confusing.
