An X Fairy is any mystical creature who, commits a terrible crime, most often, murder. The punishment for such a terrible creature is exile. That is what it's strange when a good, polite Elf named Dekon becomes one. Even though the reason he killed was to save his mother from a Goblin. Never the less, he is banned from his peaceful home of Elfia. He is sent out into a new world. With no where else to go, he follows a mysterious map to the dangerous empire capital of the Goblins. Even he is not sure what awaits him there.
