>WARNING! SPOILERS!<
Airy's entire purpose in life was to connect every world so that her master, Ouroboros, could devour them and become a god. However, she was defeated by the four heroes and betrayed by her master, taking away her power and absolutely obliterating her. But what if Ouroboros had even the smallest bit of mercy? What if, during her power drain and eventual consumption, he sent her away to another world in exile?
Airy wakes up in a house with all of her memories intact, but she feels powerless. It certainly doesn't help there's a unconditionally kind horse, a smart aleck rabbit, an odd amalgamation of different animals, and a group of adventurous young girls. Just where did she end up?
(Bravely Default crossover, and probably the very first one ever in existence. Anyway, there are going to be spoilers everywhere [such as references to the final battle and the sort], so if you don't like that, turn away now. Well, first you can leave a Like for this being the first Bravely Default story ever, then you can leave. Thank you!)
