You are the Avatar! As the only physical being with the ability to bend all four elements, it is considered the Avatar's duty to master the four bending arts and use that power to keep balance among the four nations of the world, as well as between mankind and spirits. Wow, go you!
I have not finished Bravely Default yet but it's really awesome! and Fantasy Life is gonna be kinda like Monster Hunter/Harvest Moon if that explains anything haha. I'd go back to Animal Crossing if I could play with you!
