Ravendia is a 5000 year old dragon who is constantly attacked due to his frightening appearance, even though he is actually a weak coward and a vegetarian. One day, an orphan named Reiko offers to sacrifice herself to him if he would defeat the Demon Lord in exchange. Not wanting to harm her, he pretends to eat her soul. However, this makes her believe she has become his disciple, and her sheer belief causes her to awaken magical powers and monstrous super strength. Reiko drags an unwilling Ravendia on a quest to defeat the Demon Lord, but he starts to care for her.
