Lute, a cheerful and enthusiastic young boy, dreams of becoming the world's top monster Rider. But no one ever said that getting there would be easy. Every step Lute takes brings a new challenge to overcome. Fortunately, he has his friends to help him along--Cheval, a fellow apprentice Rider, Lilia, a young girl who dreams of leaving the village and seeing the world, and Navirou, a loyal catlike companion. Together they spend their days training in the isolated Hakum Village, working hard and making it through one trial after another.
