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...

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

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.
