Salt wind off the northern ocean whips through the rigging of a ship that has no business crossing into uncharted waters. Natsu Dragneel hangs over the rail, fire sputtering green in his gut, while Lucy Heartfilia clings to the mast and Gray Fullbuster and Erza Scarlet trade barbs to mask the same queasy thrill vibrating through them all. One year ago they buried Acnologia and Zeref. One year ago the war ended. Now they are sailing toward the continent of Guiltina to accept a mission that has sat on the request board for over a century, untouched because every wizard who tried it either crawled home in pieces or never crawled home at all. The 100 Years Quest. Even Gildarts turned back.

The client waiting on the far shore is no ordinary employer. Elefseria is an immortal Dragon Slayer, the founder of the first magic guild, and the law written in his scales is knowledge itself. He does not ask them to kill. He asks them to seal — five renegade dragons called the Five Dragon Gods, each wielding power that rivals the nightmare Fairy Tail barely survived. Mercphobia, the Water Dragon God, has already drowned a city. Aldoron, the Wood Dragon God, sleeps beneath an entire metropolis and dreams destruction. Ignia, the Fire Dragon God and son of Igneel, issues Natsu a challenge that burns hotter than any bond of blood. Meanwhile, back in Magnolia, a spirited new recruit named Touka weaves herself into the guild with a smile that hides a blade — the White Wizard Faris waits coiled inside her, ready to brainwash Fairy Tail in a crusade against all powerful magic. Natsu's team will find that the 100 Years Quest is not a single mission. It is a continent of enemies, and the dragons are only the first to bare their teeth.
