An all-new original story storyboarded by Hiro Mashima, the author of Fairy Tail, released on February 17, 2012. "Natsu's Secret" is going to be revealed in the "Past World"?! Guided by a "magic book" that's lying in the Guild's storage room, Natsu, Lucy, Happy, Gray, and Erza have traveled back into the past!!

Mavis is bored staying alone in Tenrou Island, so she decides to pay the guild a visit, unaware that the Fairy Tail members are going to the beach for a training camp which she decides to tag along as well. The group faces a lot of trouble that are caused by Natsu and Gray. What would happen if the girls got drunk?

During the Grand Magic Games, the Mages of Fairy Tail head to the popular resort known as Ryuzetsu Land, seeking to relax. While interacting with their friends and even members of other guilds, the crazy antics of Fairy Tail soon lead to trouble for everyone.

In a town far away, Lucy, Natsu and Happy, from Mashima's Fairy Tail manga, are on a mission to find a troublemaker and deal with her. Due to unknown circumstances they get separated. The same happens to Elie and Haru, from Mashima's Rave Master manga. Lucy and Elie manage to meet each other and together they try to find their respective partners..

Due to the bet they made during the Grand Magic Games, the time has finally come for Team Fairy Tail A and B to decide who will have the privilege to make the other team do whatever they desire, leading to a day's worth of antics from the two parties.

After Erza recruits Natsu to assist Mavis by allowing her to enjoy the qualities of a hot bath, Team Natsu and Juvia take up Warrod's request to look for a hidden treasure buried by the First Master herself 100 years ago, although the task becomes much harder than it was initially let on.

Lucy's apartment becomes the venue for a Christmas party for some of her friends. But the celebration soon devolves into chaos as Erza forces the rest of the guild into playing the Guild Master's Game with her. Erza proves merciless as she orders her friends to perform embarrassing acts. Gray finally manages to avenge everybody and orders Erza to walk home naked at the end of the game. As she leaves the party, she runs into Jellal, who kindly covers her up and accompanies her home.
