In the midst of a war, a child is born during a bloody battle at the cost of his mother's life. From this baby comes forth a huge and powerful dragon born of Shadow. Within minutes the dragon lays waste to the landscape, but a quick-thinking knight locks the baby in a cage of darkness, where he grows to be a young man, knowing only the kindness of his young female tutor. Until the day the Shadows attack and he is set free... Hot on the heels of Ganette, a fellow Fusion Type on the same warpath to Opsquria's castle, Ral's ego leads him to make reckless mistakes. Alienated from his companions and racing ahead on his own, he heads straight into the enemy's sticky trap. Without the guidance of his tutor Mio, can he overcome his pride before it costs him everything—even his own life?!
