Natsu, Lucy Heartfilia, Gray, Erza, and Wendy are chosen to represent their guild in the Grand Magic Games, which are to be held in Fiore's capital, Crocus. As they tour the city, Natsu and Happy encounter the twin dragon slayers, Sting and Rogue, who mock Natsu for not being able to kill Acnologia, and boast of becoming true dragon slayers by killing the dragons who raised them. At midnight, Fairy Tail and the other participating guilds are put through a preliminary event—a race through a massive floating labyrinth—designed to narrow the number of participating guilds down to eight teams.
