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...

Dragon Eaters are after Mercphobia to gain the power of Water God Dragon. Natsu and the others join in the battle to aid him, but the foes are strong. Meanwhile, Gajeel, Juvia, and Lily investigate Touka despite the protest from Levy.

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.

It turns out that Wraith used to be a Fairy Tail wizard, and Makarov and Wraith were a guild family. Meanwhile, Wendy struggles against Nebaru, and Lucy starts collecting the other Fairy Tail members with the help of Cana and her Magic Cards.

Natsu and Happy find out that Touka is actually a cat, and she has mistaken Happy as Natsu. Meanwhile, Laxus unleashes his new skill, Red Lightning, against Erza. Now it's down to two orbs, but when Happy throws an orb at the White Mage...

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.
