Chapters: 24-46, Episodes: 11-20
Short SummaryNatsu steals a S-Class job request from the guild's top floor (a act forbidden in their rules) in the hopes of becoming an S-Class wizard, and drags Happy, Lucy, and Gray into the fiasco. The mission sends the group to an island where a mysterious plague transforms its residents humans into monsters under the light of the moon. As they investigate, Gray finds that this situation has ties to his past.
Galuna Island Arc has the following tropes:
- Anti-Magic: Yuka's specialty.
- Attack of the 50-Foot Whatever: Angelica, Sherry's pet rat.
- More importantly, Deliora.
- Dark Is Not Evil: Despite being demons, the islanders are revealed to be quite friendly when they get their memories back.
- Big Bad: Lyon Vastia.
- Five-Man Band:
- Foreshadowing: Natsu notices Zalty smells like a woman. As it turns out, he is Ultear in disguise.
- Harmless Freezing: Natsu gets a sphere of ice frozen around him. Other than some impaired movement, he's fine. Subverted with Deliora, who is dead after having been frozen for years.
- Heroic Sacrifice: Ur, who turned herself into ice to stop Deliora in Gray's flashback.
- Honor Before Reason: Erza when she arrives on the island to bring the bunch home in violating of Fairy Tail's rules. She has to be talked into helping the others.
- Laser-Guided Amnesia: The effects of the Moon Drip on the villagers.
- Love Freak: Sherry.
- Nice Job Breaking It, Hero!: Gray's plot to exact revenge on Deliora in his youth not only leads to Ur freezing herself to stop the demon, but it also inflames Lyon's anger with Gray.
- Reality Ensues: Because Natsu stole an S-Class job request against Makarov's direct orders, Erza has no choice but to try getting him, along with Lucy, Happy and Gray, to return to the guild.
- The Reveal: Threefold:
- The ice over Deliora is Gray's and Lyon's teacher, Ur.
- The islanders aren't humans cursed to be demons. They're demons who can turn to human form and just lost their memory due to the effects of the Moon Drip.
- Ur's daughter, Ultear, is still alive.
- Revenge Before Reason: Gray's mindset when he was little, which lead to tragic consequences.
- Samus Is a Girl: Zalty, who turns to out to be Ultear, one of the Magic Council members.
- Screw the Rules, I'm Doing What's Right!: Gray to Erza when she tries to cowtow him into coming back to Fairy Tail.
- Sealed Evil in a Can: Deliora, who was sealed inside within a huge block of ice made from Ur's body.
- "Shaggy Dog" Story: After all's said and done, Deliora is a unfrozen... but crumbles upon release since he had died after being frozen for so long.
- Trap Door: Lucy has the idea to build one of the covered pit variety. Nobody thinks it'll work, and then it does on the wrong people. Repeatedly.
- Weird Moon: A purple colored one. Subverted in that it was magic crystallizing like a dome over the island and the tint of it made the moon look as such.
