Fairy Tail OVA (2016)

After the Grand Magic Games end without a clear winner between Fairy Tail's two teams, Makarov settles the matter with rock-paper-scissors. The losing side must obey the winners, launching Natsu and his friends into a ridiculous punishment mission. Later, a story from Mavis's past sends the guild searching for an old treasure tied to Fairy Tail's earliest days.

When Christmas arrives in Magnolia, the guild helps prepare the city before gathering for a party of its own. Drinks, games, rivalry, and the members' complete inability to celebrate quietly soon transform the holiday into exactly the kind of chaos Fairy Tail knows best.
