10-year-old Erin is a young girl who lives with her mother in the Tai Koh Region in the small Village of Ake. She has a big love for animals, especially the Touda, dragon-like creatures used in the war. Her mother Soyon was originally of the Mist People, an ancient clan who have members with green hair and eyes, and is rumored to follow in the ancient ways, practice magic, and hide in the mist. But despite her genealogy, they stay in the village because Erin's late father was the son of the village chief and Soyon is the head Touda doctor. But one night, the Kiba, the Duke's strongest Touda, mysteriously die. According to law, since Soyon was the person who was charged with caring for them, she is responsible for their condition and was sentenced to death. Erin learns of this and tries to save her mother, but is swayed along the river and leaves her mother to be eaten by the wild Touda. Erin is taken in the Shin Oh region and is found and adopted by a beekeeper. There, she learns of the "king of beasts" the Ohju. Erin's spark for learning takes her to the Kazalm Ohju Breeding School, and leads her to the baby Ohju Lilan. As Erin stays at Kazalm and spends more time with Lilan, she creates a miraculous bond with her that is said to be impossible and ends up getting involved in a secret war between the Tai Koh and the Shin Oh regions.
