Dion was the healer of an adventuring party but was betrayed and thrown off a cliff by his party members because they had recruited Criola, a cute girl who could heal and use damaging spells, and they thought Dion was useless. After being thrown off the cliff, Dion survived and healed a dragon that was near-death. The dragon assumed the form of a cute girl and saved Dion's life, granting him amazing power in the process. Dion now starts an amazing adventure with his dragon lover.
