The Legend of Dragnox
I am Natsu Dragneel of Fairy Tail. I am not dense as my family think I am. Actually, I am a... I can't call myself polite now can I? I am the Lost Kingdom's ruler, Natsu Dragneel. The name of my kingdom was originally, the Dragox Kingdom. Soon, because of a tragedy, we disappeared and was renamed as the Lost Kingdom. I only joined Fairy Tail for this reason: Find Fairy Tail's biggest secret, and restore my kingdom to it's original glory.
Natsu Dragneel and his guild gets a mission from the Lost Kingdom on another side of the land. They wondered about, to find out the truth and Natsu's purpose of being in Earthland. After they had reached the Lost Kingdom, Natsu suddenly declares that he has to go back to Fiore to attend to some business himself. Confused, the Fairies reluctantly agreed. What is Natsu doing in Fiore?
