The Grand Magic Games reaches its climax following Natsu Dragneel and Gajeel Redfox's stunning victory over Sting Eucliffe and Rogue Cheney of the Sabertooth guild. This success pushes the Fairy Tail guild closer to being crowned the overall champions, but obtaining victory is not the only challenge they face. A mystery still surrounds a hooded stranger and the ominous Eclipse Gate, leaving more questions than answers. More crazy adventures are on the horizon for Fairy Tail as their destructive antics and joyful rowdiness continue unabated. Their greatest trial is quickly approaching, but united as a family, the guild will always be ready to face any threat that comes their way.

In the mountains of north Fiore lies the Fire Village, where a lush-blue relic known as the Phoenix Stone is preserved. Entrusted to a mystifying woman named Éclair, it is said to contain the power of an ancient phoenix. She wanders the land alone and protects the stone from harm, despite having no memory of why it was left in her care and only the faintest recollection of where she must take it. After encountering the wizard guild Fairy Tail, Éclair receives an offer from Natsu Dragneel and his friends to help her uncover the mysteries surrounding the stone. However, in the midst of the group's journey, Éclair is suddenly attacked and the stone is taken from her. With this, nefarious intentions to revive the blazing phoenix for its unparalleled power come to light, and the wizards of Fairy Tail find themselves in a situation that could spell calamity. They must now work together to prevent the revival of the phoenix and save the world from ruin.

New York Police Department partners Dee Laytner and Randy Ryo Maclean are on a vacation in the English countryside—which Dee has sneakily set up as an opportunity to seduce Ryo. As romantic tensions steadily build, Ryo spots a dead body floating in an otherwise tranquil lake. With their intimate holiday suddenly interrupted, the pair must decide what they think is more important: solving a case or each other.

Although Fairy Tail has disbanded and its members are now spread far across Fiore, Natsu Dragneel has not given up on reuniting the guild he and others once called home. Along with his companions Happy and Lucy Heartfilia, he will stop at nothing to keep Fairy Tail and its fiery spirit alive even as they face their most difficult trial yet—the invasion of Fiore by the Alvarez Empire's immense army and their all-too-familiar ruler.
