Airy

Airy is a non-playable character in Bravely Default.

Appearance and Personality
Airy appears as a pale-skinned fairy in a white dress with butterfly wing. As Ringabel noticed, having memory of seeing a "6" and then a "4" and later a "3" when they ended up in other worlds, the pattern on Airy's wings tend to change with each world the group travels through.

Right from the start, Airy's sole purpose is to awaken all the crystals and seeks to help Agnès do so in any way possible. She has a cheerful and childish demeanor and is easily hurt when felt left out especially by Agnès or when Ringabel gets on her nerves. Airy serves as a reserve of information regarding the crystals and their importance to the world, including their locations role in helping to save the world, she also serves as a method of giving small hints of where to go next on the bottom screen when bringing up the main menu.

However, Airy is revealed to see awakening all the crystals being more important that helping others, though she expresses some concern for Agnes. It was only after her true nature is revealed that Airy displays a fanatic loyalty to Ouroboros.

Story
From the start, Airy accompanied Agnès Oblige and her group on their quest to awaken the crystals. However, deceiving the others into thinking she wants to save Luxendarc, Airy only helps in awakening the crystals to ensure the coming of her master, Ouroboros. Prior to the events of the story, Airy used an Agnes of each universe to awaken the crystals before killing her and her companions. From there, the number on her wings serving as a countdown, Airy uses brooch to invoke the Harrowing to link the world to the previous ones Ouroboros possesses. This causes the formation of the Great Chasm in the Norende Village of the next world Airy infiltrates. However, for reasons unknown, Airy spared the current group as she uses them to enact the journey five more times.

Once the current group she used outlived their usefulness, as begin to learn the truth of their quests yet continued to find out her true intentions, Airy assumes her monstrous caterpillar-like form while revealing the existence of Ouroboros. Though driven off to the Aurora of Darkness, Airy basks in Ouroboros's power to assume her butterfly-like perfect form to battle Agnès's group one final time. But once defeated, Airy finds that Ouroboros has no more need of her and promptly devours her.

In an alternate ending, when Agnès attempts to destroy a crystal during her prayer, Airy is forced to reveal her true form and battles Agnès's allies. They later destroy her at the Aurora of Darkness, unaware of Ouroboros's coming even though she taunts them by telling them of his eventual appearance thousands of years in the future in her dying breath.

Trivia

 * An interesting feature of the game that naturally occurs during Chapter 6 is that most of the letters of 'Where the Fairy Flies' turn red and disappear, leaving the phrase 'Airy Lies'. The same can be seen from the Japanese version of the game where removing the "F"s of 'Flying Fairy' turns the phrase into 'Lying Airy'.
