Natsu and friends visit the very first Wizard Guild to take a quest that no one has ever completed: the "100 Years Quest." Meanwhile, new recruits join Fairy Tail, but one of them is a little odder than usual...

Natsu, Wendy, and Erza are captured by the Diabolos, and Lucy sets out to go rescue them. On her way, she meets someone unexpected… Meanwhile, Jellal finds out the secret of Touka.

Touka the White Mage brainwashed the Fairy Tail members. She plans to destroy the orbs of the five towns on Aldoron to defeat him; Natsu and the other must fight their friends to save them from the White Mage and stop her plan.

Natsu, Lucy, Gray, and Erza fight their own Guild friends to free them from the hypnosis. Then, Wendy encounters a new Dragon Eater. And another Dragon Eater Natsu meets turns out to be...

When all five orbs are broken, something unexpected happens: The Wood Dragon God, Aldoron, is revived. It also activates God Seeds, who start attacking Natsu and the others by becoming the person who they consider to be the strongest.

Natsu turns Wolfen into a fake Zeref and uses Ankhseram's curse on Wolfen. Other Fairy Tail wizards face three other God Seeds: Metro, Gears, and Doom. Then, the leader of God Seeds, Aldoron, shows up in front of Natsu

Gray and Juvia take on Metro's main body, while the others fight his golems. In the meantime, Jellal takes on Gears. When it's down to Aldoron himself, an unexpected yet familiar face shows up: Brandish.

Gajeel turns into a giant by Brandish's magic and fights the Wood Dragon God. Now all that's left to defeat is the God Seed Aldoron. Natsu's fire burns Aldoron, who has no respect for human lives as he regards them only as his food.

Natsu and the others defeat Alta Face and save Elentear. They're reunited with the guild members in Drasil, but their 100 Years Quest continues. Meanwhile, Selene is taken to Diabolos after being defeated by Suzaku. But things are not what it seems...
