Following the inconclusive results of the Grand Magic Games, Fairy Tail's master, Makarov Dreyar, proposes a unique solution to determine the champion by having Team A and Team B engage in a game of rock-paper-scissors. The victorious team gains the authority to assign tasks to the losers. Laxus Dreyar seizes this opportunity to send Natsu Dragneel and his team on an arduous quest to recover a missing stone. Meanwhile, a somber atmosphere envelops the Fairy Tail girls as they relax in a hot spring with their original master, Mavis Vermillion. The arrival of Warrod Sequen unveils a tale from a century ago involving Mavis and a hidden treasure, prompting Natsu's team to embark on a journey to unearth the treasure and reminisce about happier times. Amidst this search, tensions arise among the founding members of Fairy Tail. In a separate festive event, the Fairy Tail guild members unite to infuse their city, Magnolia, with Christmas cheer through hard work and dedication. After a day filled with labor, Natsu and his companions come together to revel in a Christmas celebration, complete with drinks and games that quickly evolve into the lively chaos characteristic of Fairy Tail.
