In the year 2030, Beast Pods fall like asteroids from the sky and scatter all over Earth. These are actually magical creatures called Rune Beasts from another realm who have escaped their homeland destroyed by the evil Dark Angel and his followers, the Heavenly Lords. Children all over Earth pick up these Beast Pods, and discover that they can fuse with the Rune Beast inside in an extra dimension to carry out battles with one another. Our hero, Ling Qili, becomes a leading fighter after he establishes a strong partnership with his Rune Beast, Flamewind Dragon.
