Fairy Tail (2009)

Season 4: Episode 5

Natsu, Lucy, 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 his friends meet Sting and Rogue, who mock Natsu for not being able to kill Acnologia and boast killing the dragons who raised them. At midnight that night, Fairy Tail and the other participating guilds are put through a preliminary event—a race through a massive floating labyrinth—designed to narrow the guilds down to eight teams.
