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...

The town of Ermina turns out to be a city for fish, where the whole town is submerged in water during high tide. The moment the party mentions Water God Dragon, the fish turn hostile.

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...

Natsu fights Wraith, the Spirit Dragon, but Natsu's attacks are useless against him. On the verge of death, Natsu sees Zeref, Mavis, and Igneel. As a thoughtform, Natsu is finally able to attack Wraith. That's when Wraith finds a body to possess...

The outcomes of the battles are being decided... While Lucy and the others continue trying to enclose their comrades within the cards, Wendy faces off against the sticky dragon Nebaru, who wants to devour her!

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.

White Mage uses Aqua Aera, Touka's spell, to take Fairy Tail wizards to Elentear, her homeland, but they end up in Edolas. After they get reunited with the Fairy Tail in Edolas, Natsu and the others go to see Mystogan for help.

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...
