I admittedly neglected Aya for a while, so I'm gonna make up a lil bit for it starting with a new refsheet of hers which also includes her common outfits.
Unlike Ota, Aya pilots some kind of support aircraft for Aperion (which is also a living vessel for a supernatural being), and that's why her pilot outfit is different from Ota's and more resembling of a classic air pilot instead.
