Long ago, a monster called the Evil Dragon appeared on the continent. It could destroy an entire city with a single beam of light. A great mage later used a sealing technique passed down through their ancestors to seal it inside a person and eliminate its evil thoughts. The person who sealed the Evil Dragon was known as the Dragon Sealer.
Years later, the new Dragon Sealer was a child. By then, however, the Dragon Sealer had become despised by everyone. To put an end to their resentment, she decided to grow stronger. And so she began adventuring with her companions, while also eradicating the Evil Dragon's wicked thoughts once and for all.
