Legion pays Fairy Tail a special visit! Fairy Tail learns of Sabertooth, the number one guild in Fiore! And what lies beneath the original Fairy Tail base of operations?!

Natsu meets up with Max and they decide to have a showdown. Being pushed back, Natsu has to enter his Lightning Flame Dragon Mode to defeat Max. Surprised at the difference between the power 7 years ago and now, Natsu and others visit Porlyusica to ask her for a medicine. At the guild, Makarov attempts to announce a new guild master but the things are quickly turned around when everyone finds out that Gildarts decided to leave for another journey. Later, with teary eyes Wendy tells everyone that Porlyusica's smell and voice reminds her of Grandeeney. Back at the guild, Makarov decides that Fairy Tail will join an exciting event in order for them to regain the top spot - the Grand Magic Games.

Fairy Tail's best is back, but to rock the Grand Magic Games, they've got to make up seven years worth of time in only 3 months! It's time for some seriously hard training! But before that, a little party in the Spirit World can't hurt, right?

There are only five days left 'til the Grand Magic Games begin, but Natsu and company still aren't ready for it. But then they meet up with Crime Sorciere, a small, independent guild led by an old frenemy. The members of this newish guild promise to help Fairy Tail "power up" in exchange for a favor...

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.

In the elimination round, Natsu and the others have to make their way through the Sky Labyrinth, a giant mind-bending maze full of rotating walls and vicious rivals!

Having barely qualified to continue in the Grand Magic Games, one of Fairy Tail's representatives has to be replaced. As the competing guilds are introduced, Natsu and the others size up their competition--which includes an unexpected set of foes.
